One benefit of all the rains were fewer grasshoppers overall

A grasshopper seems to be waiting patiently for a train to pass near Kerens in Central Texas. Grasshopper populations are generally much lower in most of the state this year, most likely because of the excessive late winter and spring rains, said Dr. Allen Knutson, a Texas A&M AgriLife Extension Service entomologist, Dallas.

COLLEGE STATION – Though there have been reports of high grasshopper populations in some areas, generally the pest’s numbers statewide are much lower this year.

“Our expectations this year were that grasshopper numbers would be lower because during heavy rains and higher humidity, grasshoppers are more likely to die from fungal diseases, “said Dr. Allen Knutson, Texas A&M AgriLife Extension Service entomologist, Dallas. “We’re getting a few reports of grasshoppers, but overall the numbers are much less than in previous years.”

In the Central Texas Blacklands, only Ralph Davis, AgriLife Extension agent for Kaufman County, mentioned seeing large numbers of grasshoppers.

However, in the Panhandle, Mike Bragg, AgriLife Extension agent for Dallam County, said that as rangelands dried out, grasshoppers were moving into cropland, requiring some producers to spray pesticides.

In East Texas, Armon Hewitt, AgriLife Extension agent for Trinity County,
noted increasing grasshopper numbers, but his was the only county where troublesome numbers were reported. In the West Central District, Heath Lusty, AgriLife Extension agent for Lampasas County, noted that “lots of small grasshoppers were beginning to show up.”

Generally, however, the incidents of grasshoppers were low as was expected, Knutson said. This doesn’t mean producers shouldn’t be on the watch for the pest. It’s still possible for populations to explode in isolated areas.

Knutson also said that though incidences of the sugarcane aphid have been lower than expected this year, the pest is now showing up in Blacklands fields.

“We’re seeing some of the first sorghum fields in the northern Blacklands being treated for sugarcane aphids,” he said. “Also, forage sorghums should be monitored closely too for this pest, because it can be very damaging to crops like Sudan grass and haygrazer.”

Though the sugarcane aphid numbers haven’t increased until recently, now that hotter, drier summer days are here, populations can get out of control very rapidly, Knutson said.

AgriLife Extension district reporters compiled the following summaries:

The 12 Texas A&M AgriLife Extension Districts

Central: Rangeland, pastures, livestock and most crops were all rated as being in good condition. Drier conditions during the past week were favorable for crops. Grain sorghum in particular looked very good. Corn maturity was highly variable. The wheat harvest was completed with some low test weights and some sprout dockages. Stock-water tanks were full, and lake levels were up. Sugarcane aphids were found in many forage sorghum fields. As most producers will start harvesting sorghum silage very soon, some fields will have to be sprayed. Bermuda grass stem maggots were also found. Hay harvesting was proceeding well, with yields ranging from four to six round bales to the acre. Though oats in some fields were laid down by earlier high winds and heavy rains, the harvest was considered good. Irrigation of crops will start soon.

Coastal Bend: Some areas had a few short showers, but hotter, drier weather generally prevailed, which made good growing conditions for most field crops and forages. The hot, dry weather also allowed fieldwork and hay harvesting. Corn was maturing and drying quickly. Hay harvest continued with very good yields. Most grain sorghum neared being ready to harvest, although combining will be difficult in fields where the wind from Tropical Storm Bill caused lodging. Cattle were in excellent condition, and pasture grasses were knee high. Cotton and soybeans were progressing well, though some fields needed more moisture to reach full yield potential.

East: Weather around the region became more normal for this time of year. Producers were baling hay as fast as they could. Some pastures were still not traversable with heavy equipment due to water in low-lying areas. In Anderson County, some areas along the Trinity River were still under as much as 5 feet of water. Most counties had adequate subsoil and topsoil moisture. Brief afternoon showers caused problems for hay production. Most hay fields were producing more hay per acre than normal – as much as three bales per acre — but the quality was down due to the delayed harvest and producers not being able to make applications of herbicides and fertilizer in a timely fashion due to the rain. Livestock were in good condition. Horn fly populations were still stressing livestock. Cattle were loaded with flies. Vegetable growers were harvesting peas, corn and tomatoes to sell at local farmers markets. Mayhaw, blackberry a nd blueberry growers had another great season. Peach yields were light due to pressure from continued rain and the resulting plant diseases. Most counties had a good watermelon crop, except Panola County, where heavy rains fell at the wrong time, knocking many of the blossoms from the vines. Pecan scab was present in orchards and landscapes. Mosquitoes and houseflies were still a major threat and nuisance. Feral hogs and grasshoppers were active.

Far West: All counties reported rainfall from 0.7 inch to 2 inches, which kept pastures and crops green. Temperatures continued to be mild for this time of year. Livestock continued to do well. Replanted cotton looked good but was behind normal growth.

North: Topsoil moisture was mostly adequate. Weather was generally mild, with some areas receiving from 0.3 to 1 inch of rain. Corn looked a little better than it had earlier, though uniformity of stands was still an issue due to some fields having standing water throughout emergence. Summer pastures were doing well with grass growing at a great rate. Soybeans and grain sorghum looked good. Late-planted cotton emerged. Producers were harvesting hay where fields had dried out. Livestock were in excellent condition, and calves were doing well. Wild hogs continued to damage pastures and crops. Grasshopper populations were expanding in some areas.

Panhandle: The region was hot and dry for most of the week, with rain on the weekend. Some areas of Dallam and Hartley counties received from 0.1 to 0.45 inch, with 0.2 inch common. Hansford County got 0.75 to 1 inch. The progress of the wheat harvest varied, from being well along to just starting. In Deaf Smith County, wheat yields were about average. In Randall County, about 60 percent of wheat was harvested, with yields ranging from 30 to 60 bushels per acre. The Hansford County wheat harvest was nearly completed, with irrigated fields making from 45 to 60 bushels per acre. Some wheat fields had been taken over by weeds and were being plowed under instead of farmers spending money to spray the field. Irrigation of corn was active, and some producers were cultivating and side dressing the crop with anhydrous ammonia. Corn was behind in maturity in some areas. In Hansford County, early planted corn tasseled, but the late-pl anted corn was far behind in development. Grain sorghum varied in maturity as well. Deaf Smith County grain sorghum was doing well, with earlier plantings at the six-to-eight leaf stage. Late plantings ranged from just emerging to the three-leaf stage. Ochiltree County sorghum planting was just completed. Most Randall County sorghum was rated as being in excellent condition. High temperatures increased livestock’s water needs, and with no wind to turn windmills, some producers started hauling water.
Cattle were in good condition across the region, though some pastures were beginning to turn brown. Grasshoppers were moving out of drier rangeland into cropland causing some producers to make broader insecticide applications.

Rolling Plains: Conditions returned to normal in the region, with little to no rainfall over the past few weeks. The dry conditions allowed producers to finish planting cotton. Planted cotton was in good to excellent condition, with only a few acres being in poor shape due to excessive rainfall during planting. Soil moisture remained favorable, though later-planted cotton had a harder time getting started due to the lack of rainfall during the past several weeks. There was only low to moderate pressure from fleahoppers and thrips. Pastures and livestock were in good to excellent condition. Earlier rains gave rangeland the boost needed to meet grazing demand. Some ranchers were beginning to restock herds but were mindful that if rains stop, they don’t want to be overstocked. High cattle prices were also making producers cautious on restocking. Hay yields were excellent, and the peach crop outstanding.

South: Scattered showers continued throughout the South Region. Some areas received light showers and some received pretty heavy downpours — resulting in good rainfall amounts to add moisture to already adequate soil moisture conditions. In the northern part of the region, peanuts were developing nicely and flowering, and some producers were spraying the crop with fungicides. Corn and grain sorghum were maturing, and cotton was setting bolls. Rangeland and pastures remained in good condition, and cattle body-condition scores were excellent. Soil moisture was mostly adequate in the northern counties. In the eastern part of the region, rains kept temperatures under 100 degrees. Jim Wells County received from 0.5 inch to 2 inches, which kept fieldwork minimal. Kleberg and Kenedy counties did not receive any rain, but cotton and small grain crops were said to be the best in the past decade. Ranges and pastures were excel lent. Soil moisture was mostly adequate, with Kleberg and Kenedy counties having 80 to 100 percent surplus conditions. In the western part of the region, some areas received nearly 2 inches of rain. Coastal Bermuda grass producers had plenty of round and square bales laid out in fields throughout the area. Hay was for sale at dramatically reduced prices. The scattered showers delayed some field activities, but corn, sorghum and cotton were progressing well, and watermelon harvesting preparations continued. There was some insect pressure on cotton, but it was below the economic threshold for any pesticide applications. Pecans continued to make good progress. Soil moisture remained adequate in most of the western counties. In the southern part of the region, showers in Cameron County halted the harvesting of corn and grain sorghum. In Hidalgo County, rain held up the harvesting of sunflowers, sorghum and sugarcane. Harvesting of row crops and hay continued in Starr County despite ligh t showers. Willacy County received about 1 inch to 3 inches of rain, which stopped the grain sorghum harvest for about two days. Corn throughout the area looked good. Soil moisture was mostly adequate in the southern counties, with Willacy County having 50 percent surplus topsoil moisture.

South Plains: Crops in most of the region were off to a good start due to all the early season rains but needed more moisture soon to keep progressing. The Bailey County wheat harvest was ongoing with excellent yields. Cochran County cotton progress ranged from five to 12 true leaves. Even with the dry conditions, Cochran County corn and grain sorghum were making excellent progress. Peanuts were also doing very well. Lubbock County growers began irrigating grain crops as soils dried out. Many Lubbock County cotton fields were squaring, and grain sorghum ranged from just planted to the early boot stage. Early planted cornfields were tasseling, and sugarcane aphids were detected. In Garza County, cotton was progressing well in most areas despite high weed pressure. No insect pressure was reported. Rangeland and pastures were in excellent condition. Mitchell County cotton was growing fast and showed signs of squaring in early pl anted acres. Weeds were a problem in cotton fields there too. Shortly after a sand fighter cultivator was run over a field, new weeds emerged. Scurry County cotton was a little behind but was expected to catch up soon.

Southeast: Soil moisture varied widely but was mostly adequate to surplus, with Hardin, San Jacinto and Chambers counties having 100 percent surplus levels. Rangeland and pastures in those counties were mostly good to excellent, with good ratings the most common. Walker County producers were harvesting hay. In Montgomery County, warm temperatures and rain promoted grass growth, but wet conditions made it difficult to put up much hay. Chambers County producers were able to make some herbicide applications to hayfields, but very little was cut due to weather conditions. Fort Bend County producers were also able to cut and harvest hay despite scattered showers bringing from 0.5 inch to 1.7 inches of rain. The county, like much of the region, needed a few weeks of dry weather to enable sorghum growers to begin harvesting. Brazos County also had scattered showers across the entire county. Warm-season grasses were growing rapidly, an d grasshopper populations were increasing in some areas. Waller County corn was in poor condition due to too much water. Pastures continued to improve, and rangeland was in good condition. For the first time in weeks, Brazoria County did not have heavy showers during the reporting period. In Chambers County, rice acreage was about half what it was in 2014. Some organic rice was planted right up until the last week of June.

Southwest: Drier weather improved conditions throughout the counties, and soil moisture became more manageable. With good growing conditions and earlier rains, Gillespie County peach growers were expecting a record-setting year. Some areas had problems with grasshopper infestations. Livestock and wildlife were in excellent condition with good forages and grazing on rangeland.

West Central: Days were hot and windy with warm nights. There were a few scattered showers, but the wildfire potential increased as tall grass in fields dried out. The wheat harvest was completed in most areas, with fair yields reported. Row crops continued to make good progress with plenty of moisture and good growing conditions. Summer forage crops were being harvested for hay with very good yields. Grain sorghum fields looked good. Cotton planting was mostly finished in all areas, and most of the planted crop had emerged. Producers were spraying cotton fields for weed control and scouting sorghum fields for sugarcane aphids. Some had to spray to control the pest. Hay producers continued cutting and baling, with good yields and high quality. Some hay fields neared being ready for a second cutting. Rangeland and pastures further improved due to recent rains. Livestock remained in good condition. Flies continued to be an is sue, and small grasshoppers made their appearance. Pecan trees were doing well.

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.
