Fire, rain had nominal impact on South Central Texas agriculture

UVALDE – “I’ve seen fire and I’ve seen rain.” That lyric from a ‘70s James Taylor song would certainly apply to the residents of South Central Texas over the past few months.

But while Mother Nature has been less than kind to this region, the agricultural losses caused by these natural woes have been less than expected, according to Texas A&M AgriLife Extension Service experts.

While the recent fire in Bastrop County destroyed thousands of acres, most agricultural losses were among small-acreage landowners and few livestock were lost. Many livestock were protected and fed at the Livestock Supply Point, shown here, set up by the city of Bastrop, the Texas Animal Health Commission and the Texas A&M AgriLife Extension Service.

“Most of the losses from the fire were small-landholder losses and didn’t have too much of an agricultural impact,” said Rachel Bauer, AgriLife Extension agriculture and natural resources agent for Bastrop County. “Some fences around ranches were burned, but there was little loss of livestock. Some smaller livestock, like sheep and goats were lost to the fire, but no large animals that I know of  were lost.”

Pastures hit by the fire were already greening up and did not appear to have suffered any long-term damage, she said.

In the agriculturally prolific Winter Garden area, which consists primarily of Dimmit, Frio, La Salle and Zavala counties and includes parts of Atascosa, Maverick, McMullen, Bexar, Medina, Wilson and Uvalde counties, recent flooding did not damage many crops, said area producers  and AgriLife Extension personnel.

“We’re still too wet for planting or harvesting crops,” said Jay Karnes, president of Winter Garden Produce in Uvalde. “The recent flooding destroyed one of our producer’s cabbage crops, but overall the quality and yield of other crops hasn’t been affected.”

While some of the area’s producers have taken a pretty hard beating this year, overall the rains have benefited corn, cotton and grain sorghum crops, said Rob Hogan, AgriLife Extension agricultural economist in Uvalde.

“Producers will also continue to benefit from recharged water sources and from the improved moisture in the soil profile,” Hogan said.

He said additional moisture in the region’s soil will help reduce the amount of water typically used to irrigate crops, which will help lower producer costs and improve their bottom line.

“The spinach harvest has begun and spinach producers are seeing really good yields and quality in what they’ve harvested so far,” said Dr. Larry Stein, AgriLife Extension horticulturist in Uvalde.

The region’s pecan trees also got a boost from recent rains, Stein said.

“The pecan crop this year was good,” Stein said. “Besides that, the pecan trees will now have additional moisture in the soil profile going into winter, which will help protect them from freezes and provide protection for them while they ‘sleep’ through the winter.”

Livestock will also be beneficiaries of recent rains, though not without some potential trouble, said Dr. Rick Machen, AgriLife Extension livestock specialist, Uvalde.

“While the rains are providing lots of forage in area pastures, which is good for all area livestock, some livestock, especially sheep and goats, likely will experience greater parasitism due to the wet conditions,” Machen said.

He said young calves are more likely to have parasites this year than in the past several years due to continued wet conditions.

“Producers need to remember to stay on top of this problem, particularly by taking whatever proactive and preventive measures they can to protect their animals,” Machen said.

 

AgriLife Extension district reporters compiled the following summaries:

PANHANDLE:  Daytime temperatures were slightly above average, with cooler nights. Soil moisture was rated mostly adequate and some areas received their first freeze. Collingsworth County harvest activities were in full swing before moisture and a cool system moved in. Yields were average to above average for cotton. The peanut harvest was near completion though yields were below average for the most part.  Winter wheat was emerging and producers said it looked to be a potentially solid year for the wheat crop. Dallam and Hartley counties had seasonable weather, allowing for good harvest progress. The corn and grain sorghum harvest was winding down. The sunflower harvest made good progress with only about 25 percent remaining in the field. The cotton harvest began. Corn yields were mostly average and grain sorghum yields were mostly better than expected. Sunflower yields were varied in yield and oil content, but generally yields ranged from 1,800- 2,200 pounds per acre. Several hard, killing freezes turned pastures brown and supplemental feeding continued for cattle on grass. Some stocker cattle were put on early planted wheat pasture.

Deaf Smith County yields were average to somewhat above average, depending on the hail events this summer. Grain sorghum harvest continued with many of the acres lodging from wind and poorly developed root systems from this summer. Yields on dryland sorghum were above average with several producers reporting 4,000-6,500 pounds per acre on dryland acres. Winter wheat was progressing well, and producers were turning out cattle to start early grazing. In Hutchinson County, rain delayed some harvesting, but it was still almost complete. Corn has been harvested and the rest of dryland sorghum was harvested as moisture levels allowed. Some Lipscomb County fields were too wet for a combine while the Ochiltree County grain sorghum and corn harvest resumed due to drier conditions. High winds caused lodging in some sorghum fields. The cotton harvest began and wheat planting was in its final stages.

Randall County weather conditions were good so harvesting continued. The corn harvest was completed with average yields reported to be averaging around 160 bushels per acre. The grain  sorghum harvest was underway with yields averaging about 4,000 pounds per acre. The cotton harvest also was underway with yields reported as averaging around 1.5 bales per acre. Wheat planting was about 90 percent completed and looked exceptional, according to reports.

SOUTH PLAINS:  Bailey County producers continued the cotton harvest, but grades were poor. In Cochran County, soil moisture levels declined due to high winds. The corn, pea and peanut harvests were completed. Cotton, sorghum and sunflower harvesting was ongoing. High winds slowed the cotton harvest. Pasture and rangelands were in fair to good condition. Winter wheat was being planted. The first official freeze of the season was recorded. Unsettled weather hampered harvest due to sustained high winds and high humidity. For the most part, the area remained dry, with only a trace of rainfall recorded. Cotton and grain producers made good harvest progress. The cotton harvest continued in Garza County with better than expected yields in some fields. Drip-irrigated cotton fields were averaging 2.5-3 bales per acre, center pivot irrigated fields were averaging from 1.5-2 bales per acre and dryland yields ranged from 0.75 to 1.5 bales per acre. Rangelands and pastures were in mostly good to excellent condition and cattle were in mostly good to excellent condition. In Scurry County, producers were harvesting cotton fields that were treated with harvest aids. Wheat was growing well, but still needed rain.

ROLLING PLAINS: Weather was pleasant with daytime temperatures staying in the 70s. Parts of the region received their first frost/freeze, but it didn’t last long enough to defoliate trees and cotton plants. The frost did, however, help farmers eliminate the need for some defoliates. A few cotton producers were harvesting, but the main harvest period is expected in the next week or two. Moisture helped pastures and wheat get a head start. Winter rye turned pastures green again and the wheat harvest was expected to be adequate to feed cattle through part of the winter. Recent rains allowed producers to put up an abundance of hay.

NORTH: Topsoil moisture varied from adequate to surplus with rainfall from 5 to 8 inches across the region. Nightly temperatures were in the 40’s with daytime temperatures in the 60’s and 70’s. Bermuda grass pastures greened up well, as did winter pastures. Both warm- and cool- season forages were thriving. Winter wheat was emerging, but generally there was a little too much precipitation for wheat crops. Some wheat fields stood in water for a little while so the consistency of emergence was affected. Hay supplies were looking adequate, but the quality was not as good as usual due to rains received last spring and early summer. Temperature changes caused stress in livestock and feral hogs caused more damage to fields.

EAST: Wet conditions remained across the region. Most counties reported pasture and range conditions as poor to fair. Subsoil and topsoil were reported adequate. Warm-season forages greened up but made slow growth. Winter forages were making good progress. Cool-season vegetable crops were growing rapidly. Rains damaged some crops. Ponds and lakes were filling with some counties reporting full to overflowing. Fields were saturated. Cattle were in good body condition with some producers feeding hay and providing supplemental feed. Anderson County producers reported cattle were eating acorns. Fall calving was in progress. Some producers were palpating cows to avoid the high costs of wintering open cows. Producers continued to sell market-ready calves along with cull cows. Cattle prices were weak. Houston County reported calf prices $10-$20 or lower. Upshur County reported soil samples were being taken to prepare for spring pastures. Feral hogs continued to cause damage across most areas of East Texas. Gopher and mole control continued.

FAR WEST:  El Paso County experienced warm days with cool nights, plus had its first freeze,  which will speed up the opening of pecans and their harvest. All counties reported rain showers and windy conditions due to cold fronts passing through. High winds helped dry topsoil but also caused fire danger in some counties. Cotton harvest was in full swing and should finish soon. The sowing of winter wheat continued and emerged crops looked good, with the exception of a few areas with nitrogen deficiency due to standing water. Producers were wrapping up fall cattle works with some cull cows being shipped and others being fattened up for sale early next year. Pastures were in fair to good condition with topsoil and subsoil moisture being adequate.

WEST CENTRAL: Mild days were followed by cool nights, with the weather generally warmer than normal for the time of year. Planted oats and wheat were doing well, but continued rains delayed some field work. Small-grain producers were waiting for fields to dry up to resume planting. Growers were hard at work stripping and picking cotton in hopes of finishing before more rains came. Wheat was being planted behind cotton as the cotton was harvested. Range and pasture conditions continued to improve due to recent moisture. Winter forages and grasses were coming in strong. Winter weeds were lush. There were many green pastures providing grazing for livestock. Livestock were in fair to good condition. Cattle prices were still good though the market had been soft. Supplemental feeding was in full swing. The pecan harvest was underway, but as this was an off-year for pecans, producers were expecting a below-average pecan crop.

CENTRAL: Soil moisture was good in the entire the region, with range and pasture conditions good in 95 percent of the region. Overall crop conditions were fair, but small-grain planting was delayed due to wet conditions, which also halted field work. About 20 percent of wheat was planted. Stock tanks were full and pastures were in good condition. Cattle were in good condition and recent rains continued to provide much-needed moisture for rangelands. There were only a few dry days for harvesting cotton and pecans, and pecans harvested were of average quality. Oats and wheat were late coming up. Stocker operators were expected to be later than normal turning out on winter grazing.

SOUTHEAST:  Additional rains helped replenish soil moisture in Walker County. Cool-season forages were growing well. In Montgomery County, the winter annual planting progressed well due to moderate temperatures and adequate moisture. Rainfall amounts were less than one inch for most areas of Montgomery County. In Waller County, the growing season was coming to a close. In Brazoria County, the weather was fair and the small amount of rain was welcomed. In Chambers County, the pastures were wet and the ratoon crop of rice was being harvested.  In Fort Bend County, the weather was fair and dry. Livestock were in good condition. Galveston County received heavy rains and had standing water in numerous areas.

Soil-moisture levels throughout the region varied widely, mostly in the adequate to surplus range with adequate being the most common. Fort Bend, Grimes, Walker and Lee counties reported 100 percent adequate moisture and Galveston County reported 100 percent surplus. Rangeland and pasture ratings varied widely, mostly from fair to good, with good being the most common.

SOUTHWEST: Winter wheat plantings were wrapping up. Wet conditions remained and vegetation continued to grow, including new growth on many of the brush species but at a slower rate relative to cooler temperatures. Wildlife and livestock conditions were improving, little supplemental feeding was taking place.

COASTAL BEND:  Warmer than normal temperatures and moisture led to the appearance of fall armyworms, though not on a large scale. Some producers experienced armyworm damage, and other producers were treating their fields. Additional showers throughout the week left the ground with better than average soil moisture. Pastures were in excellent condition and hay making continued. Cattle were in excellent shape and prices were high with demand even higher. Winter pasture planting was completed in some areas and the pastures continued to progress well.

SOUTH: Scattered showers with warm daytime and cool nighttime temperatures continued throughout the region. In the northern part of the region, conditions were good throughout Atascosa County. Rainfall slowed peanut harvesting but benefitted planted oats and wheat crops. There were reports of armyworms across the county and in surrounding counties. Peanut harvesting continued and wheat and oats planting continued. Some Bermuda grass cutting and baling took place in the Frio County area. No rainfall was reported in the McMullen County area, but soil moisture levels remained good as range and pasture conditions continued to improve. Forage quality also improved, so supplemental feeding of livestock  declined. Cattle body condition scores continued to improve with most herds in fair condition throughout the area.  Soil moisture conditions were 80-90 percent adequate in McMullen and surrounding counties.

In the eastern part of the region, milder temperatures and some rainfall were reported in the Jim Wells County area. Range and pasture conditions showed improvement from previous weeks as late green up occurred, resulting from good soil moisture conditions. Most farmers throughout the area reported limited wheat acreage being planted due to the probability of rainfall during the harvest season next spring. Kleberg/Kenedy counties received an average of half an inch of rainfall and experienced cooler weather. Soil moisture conditions remained at 100 percent adequate in both Jim Wells and Kleberg/Kenedy counties.

In the western part of the region, range and pasture lands continued to green up in the Dimmit County area.  Maverick County received some rain. Topsoil and subsoil moisture conditions remained adequate with a lot of moisture throughout the area. Coastal Bermuda grass remained green and ready for another cut. In the Zavala County area, field conditions improved some during the week, allowing some baby spinach to be harvested. Native range and pastures continued to improve and were producing good quality forage. Also in Zavala County, wheat and oats responded well to soil moisture availability. Cooler temperatures were forecast, which should help cool-season crops. Livestock conditions remained mostly good and no supplemental feeding by livestock producers was reported. Pecan harvesting throughout the Zavala County area was completed. Soil moisture in Zavala and surrounding counties was from 40-100 percent adequate.

In the southern parts of the region, conditions were mild and some field preparations for spring planting took place. Vegetables, especially tomatoes and onions, were progressing well in the Cameron County area. Also in Cameron County, livestock body conditions were good and forage availability was good, but weeds on range and pastures increased on improved pastures and saturated fields. Fall vegetable crops progressed in the Starr County area. Overall soil moisture conditions in this part the region were 90-100 percent adequate.

Grazing North Texas: Who’s Your Neighbor?

Published

on

By

By Tony Dean, tonydean.tx1@gmail.com

Who qualifies as your neighbor? Webster says it is someone who lives nearby, but it isn’t always that simple. Is my neighbor the person next door, or someone in the next county? It could be both.

Our neighbors are an important part of life on the ranch and the grazing lands we share. Many of us find comfort in knowing another human being is somewhere in our neck of the woods, and that someone nearby cares what happens to us.

Being a good neighbor is part of being a productive and responsible rancher, so let’s look at some of the qualities that make a good one.

Protect your neighbor

Watch out for him.

The cattle business is dangerous. Almost everything we work with is bigger and faster than we are. A mad cow can turn an otherwise wonderful day into a disaster. Sooner or later, all of us will need some help.

The average age of today’s rancher keeps climbing. Be aware of your neighbors’ ages, limitations or disabilities, and keep an eye out for anything outside their normal routine.

More women own and operate ranches today, too. Some may suddenly find themselves responsible for parts of the operation that a spouse or family member used to handle. As neighbors, we can be a valuable backup system, helping one another learn, adjust and keep the operation moving.

And then there is wildfire. It can be on us in minutes. You may need to help move a family down the road to safety or move livestock out of harm’s way. Have a plan in mind before the emergency happens.

Be a friend

Some of us who live in the country drive to town for work or make regular trips for other reasons. Others are stay-at-home ranchers, and life can get a little lonely. A friendly smile, a phone call or an invitation to lunch can mean more than we realize.

Things aren’t always wine and roses at the ranch. Few occupations ask people to juggle such a mix of complex markets, weather, natural resource management, livestock management and countless other issues.

Spirits can get low. If we are listening, we can hear and feel the stress in someone’s life. On those days, you have a chance to be a special kind of friend.

Help your neighbor

Have you ever tried to load a trailer by yourself and needed someone to stand in the gate for a couple of minutes? All of us will need help at some point, and our neighbors should be among the people we can call.

Do your best to be there when needed, and your neighbors will likely be there when it is your turn to ask. Sometimes it will be a small job. Other times, it will be a big one. It doesn’t matter. We help our neighbors.

It’s also smart to make sure someone nearby knows your ranching program and understands the land you use. At some point, one of you may need to take care of business for the other for several days.

Be cooperative

There is no end to the situations that can involve more than one family. Fencing, road maintenance and livestock getting where they don’t belong are common ones.

If you don’t handle these things with a friendly, cooperative attitude, they can create problems between neighbors that last for years.

Good fences are something to be proud of. Nothing is gained by years of bickering. Reaching an agreement may be hard at times, but neighbors should be able to work things out. Clear your head, use common sense and come up with an answer everyone can live with.

If your cattle get mixed up with your neighbor’s, make it a priority to separate them as soon as possible. It is rude to let your cattle stay in your neighbor’s pasture eating his grass while you do nothing about it.

One good way to handle strays is for the rancher whose pasture they are in to pen his own cattle along with the strays. The other rancher can then load his cattle and take them home. Afterward, both ranchers can work together on any fence repairs.

By the way, a gate between neighbors is almost always a good policy.

Take ownership

The only way to avoid mistakes is to do nothing. But it isn’t in us as ranchers to sit around and watch the world go by. We are men and women of action, so things are going to go sideways from time to time.

When that happens, and it will, own your mistakes. Decisive action can prevent misunderstandings and make a problem go away much faster.

Be honest, and never, ever lie.

Be patient

We all have bad days. When your neighbor is a little grouchy, he or she probably has something weighing on them.

That is a chance to be a good neighbor. Be patient. Be a good listener. Help your neighbor through the turmoil if you can.

Respect property boundaries

Trespassing is wrong, illegal and rude. Never do it except in an emergency.

In the Southwest, where we live, land ownership is considered a sacred right, and it is a right available to anyone. With ownership comes an expectation of privacy and respect. When you trespass, you violate those rights.

And yes, it is trespassing when you cross a fence to fish or hunt without permission. Texas is a private-property state, which makes respecting these boundaries especially important.

That doesn’t mean you can’t have an understanding with your neighbors that lets you onto their land. Many good friends and neighbors work together on one another’s ranches, but both parties should always communicate well.

You have a cell phone. Use it any time you doubt whether you have the right to go through the gate. An invitation onto another person’s ranch is a privilege, so don’t abuse it.

Your word

Your word as a rancher, neighbor, man or woman helps define you in your community and throughout your life. Your neighbors want to trust you. They want to know that all they need from you is a handshake and that they can depend on what you say.

It is a blessing to live in North Texas, where people still respect and honor a life lived with truth and love.

A good life to live

Having good neighbors is a great way to live. It brings comfort and enjoyment to life. Sometimes it takes a little extra effort, but a friendly neighborhood, even one that covers many acres, is enjoyable and can help keep all of us safer.

It is worth the effort.

The Bible

The Bible has many references to being a good neighbor. Being a good neighbor was good judgment 2,000 years ago, and it is good judgment today. Jesus made it clear that love should guide a good neighbor.

Leviticus 19:18 tells us to love our neighbors as ourselves. That is a tall order. In Matthew 5:44, Jesus takes it further, telling us to love our enemies and pray for those who persecute us.

Our goal should always be to love one another, lift each other up, and help and protect our neighbors.

All of us face drought, floods, wildfire, tornadoes, low cattle prices, rattlesnakes and feral hogs, so let’s fight the fight together. Stand by your neighbor’s side, and he will stand by yours.

A North Texas minister was recently asked, “What do you do if you have a neighbor who is really hard to love?”

His answer was short and to the point: “Love him anyway.”

Beyond Crude Protein

Published

on

By

By NTFR Staff

A stack of hay may look good from the outside. The bales may be heavy, green and free of obvious weeds or mold. None of that tells a cattle producer what the hay will provide once it reaches the feed bunk.

Two bales from the same field can differ noticeably in nutrition if they were cut at different stages of maturity, weathered differently or stored under different conditions. The differences grow even larger when you compare hay bought from separate farms or produced in different growing seasons.

A forage analysis takes much of the guesswork out by showing what the hay contains and where you may need to supplement.

Crude protein is often the first number producers check, but it is only one part of the report. Energy, fiber, moisture and possible toxicity concerns can matter just as much when deciding whether a lot of hay suits dry cows, lactating cows, replacement heifers or growing calves.

Reading beyond the protein number

Most forage reports show results on both an “as received” and a dry-matter basis. The as-received column includes the water in the hay. The dry-matter column takes moisture out of the calculation so you can compare feeds with different moisture levels fairly.

For ration planning, the dry-matter values are usually the most useful. If you’re comparing dry hay with silage, cubes or another feed, make the comparison on a dry-matter basis rather than on the numbers as fed.

Moisture still deserves attention. Hay baled too wet is more likely to heat, mold or deteriorate in storage. In severe cases, heating can create a fire risk. Moisture also affects how many pounds of actual nutrients you are buying. A heavy bale isn’t necessarily a nutrient-dense bale if much of its weight is water.

Crude protein, usually listed as CP, estimates the protein in the forage based on its nitrogen content. Protein keeps the rumen microbes that help cattle digest forage working. When forage protein drops too low, intake and digestion may decline because those microbes can’t function as well.

The amount of protein a cow needs changes a great deal through the year. A mature, dry cow in mid-pregnancy needs less than a cow in late pregnancy or early lactation. Young, growing cattle and first-calf heifers may also need more protein than mature dry cows. Hay that is adequate for one group may fall short for another.

Always compare a forage report with the needs of the cattle that will eat the hay. Oklahoma State University notes that cattle requirements vary with weight, age, stage of production, desired gain and milk production. A single protein target can’t describe the needs of an entire herd.

Energy is another major piece of the feeding decision. Many forage reports express energy as total digestible nutrients, or TDN, an estimate of the digestible energy in the feed. Protein supports rumen function and tissue growth, while energy fuels maintenance, pregnancy, milk production and weight gain.

Hay can test well for protein and still come up short on energy. That matters most for cows nearing calving or producing milk. Low-energy hay may leave cattle feeling full without giving them enough nutrition to hold body condition. University of Nebraska Extension stresses evaluating both protein and energy when judging the feeding value of forage.

Fiber measurements help explain why cattle eat one hay readily and less of another. Neutral detergent fiber, or NDF, represents much of the plant’s structural material, including cellulose, hemicellulose and lignin. As NDF rises, cattle generally eat less because bulky, fibrous forage stays in the digestive tract longer.

Acid detergent fiber, or ADF, includes the least digestible parts of the plant. Higher ADF generally means lower digestibility and less available energy. Put simply, high NDF can limit how much cattle eat, and high ADF can mean they get less energy from what they do eat.

Both numbers tend to climb as forage plants mature. Mature hay usually has more stem and less leaf than hay cut earlier. It may still be acceptable feed for animals with lower needs, but it is less likely to support lactating cows or growing cattle without supplementation.

Some reports also include relative feed value, or RFV. This index uses ADF and NDF to compare forage quality, particularly for alfalfa and other legumes. It can help when you compare similar types of hay, but it doesn’t account for every nutrient cattle need. Don’t let RFV replace a closer look at crude protein, energy and the animal’s stage of production.

Depending on the lab package you choose, the report may include minerals. Labs commonly report calcium and phosphorus, but a forage analysis can’t replace a well-designed mineral program. Water quality, other feeds and interactions among minerals all affect mineral needs and availability. Work with an Extension specialist, veterinarian or livestock nutritionist before making major mineral changes.

Nitrate and prussic acid

A standard forage analysis may not include nitrates, and you often have to request that test separately. Nitrate testing is especially important for drought-stressed forage, heavily fertilized fields and crops such as sorghum, sudangrass, sorghum-sudan hybrids, millet, oats and some weeds.

Nitrate can remain in cured hay and doesn’t reliably disappear in storage. Test any hay you suspect of high nitrate before feeding it. Oklahoma State University recommends a laboratory analysis because field screening tests can show that nitrate is present but can’t measure how much.

Prussic acid is a different concern. Unlike nitrate, prussic acid usually dissipates as properly cured hay sits in storage, though suspect forage still needs careful management and professional guidance. Be sure which test you need, and don’t treat the terms nitrate and prussic acid as interchangeable.

Putting the numbers to work

A hay test pays off when it leads to a feeding plan. Once you have the results, you can match the hay to the right class of cattle. Save better hay for replacement heifers, thin cows, late-gestation cows or cows with calves at side. Feed lower-quality hay to mature dry cows with modest requirements.

Testing can also prevent unnecessary supplementation. Without an analysis, you may buy protein tubs, cubes or other supplements your cattle don’t need. The opposite mistake costs just as much. Assuming hay is better than it is can lead to lost body condition, lower milk production, poor breed-back rates and lighter calves.

Visual inspection still matters. Don’t ignore mold, foreign material, weeds, dust or heat damage because a lab report shows acceptable numbers. At the same time, color and appearance can’t reliably predict nutrient content. University of Nebraska notes that forage nutrient values vary widely, which makes average book values a poor substitute for testing the feed you have on hand.

A forage analysis won’t make poor hay better, but it can show you how to use that hay well. For the cost of a test, you get information that can guide hay purchases, cut supplement waste and put each lot of hay where it will do the most good.

The protein number may get the most attention, but it doesn’t tell the whole story. Understanding moisture, TDN, NDF, ADF and potential toxicity gives you a much clearer picture of what is inside the bale.

Don’t Be Caught Off Guard

Published

By Savannah Magoteaux

A September rain can be exactly what a North Texas pasture needs, but that flush of green can bring an unwelcome guest.

Fall armyworms are a familiar late-summer and early-fall pest across Texas, and they can do serious damage to pastures and hay fields when conditions are right. Bermudagrass is a common target, but armyworms also feed on small grains, ryegrass and other forage crops. The key is catching them early, before a manageable infestation turns into a field that seems to disappear overnight.

Despite the name, fall armyworms are caterpillars. The adult moths migrate into Texas and lay masses of eggs on grasses, fence posts, buildings and other surfaces. Once the larvae hatch, they start feeding on plants.

Young armyworms are small and hard to spot unless you are actively scouting. As they grow, their appetite climbs. Larger larvae can strip leaves fast, leaving stems behind and cutting into available forage or hay yield.

Look for an inverted, light-colored “Y” on the caterpillar’s head. Mature larvae can reach about 1½ inches long and often have several dark and light stripes running the length of the body.

Armyworms feed most actively during the cooler parts of the day, so early morning and late afternoon are good times to scout. Walk through several areas of the pasture rather than checking only along the edge. Look closely near the soil surface and beneath grass leaves, especially where you see fresh feeding damage.

Scouting matters most after rain or irrigation. New grass growth draws newly hatched larvae, and populations can build quickly when conditions favor them.

Texas A&M AgriLife Extension generally recommends considering treatment in improved pastures when you find about three or more armyworms per square foot. The decision should also weigh the size of the larvae, how much forage is present, the expected hay value and how severe the damage is.

Timing matters. Small armyworms are easier to control than large ones, and an insecticide does less good once the caterpillars are nearly mature and have already eaten much of the forage. If you treat, follow the product label carefully, including grazing and hay-harvest restrictions.

Don’t assume one treatment or one scouting trip will carry a pasture through the season. Fall armyworm moths can keep moving into an area, laying more eggs and starting another generation of larvae. Keep checking fields even after you have controlled an infestation.

For hay producers, an approaching harvest date can also shape the decision. When the crop is close to harvest, cutting the field may be a better option than spraying. The best choice depends on the number and size of the armyworms, how much forage remains and whether the weather allows you to cut hay.

September rain is usually welcome across North Texas, especially after a long, hot summer. Just remember that fresh green grass deserves a closer look. A few minutes of scouting can make the difference between catching fall armyworms early and finding the damage after they have eaten their fill.
