Pigs pose problems for producers around the state

OVERTON — Wild pigs continue to plague farmers and ranchers in much of the state.

They are a year-round nuisance to producers, said Dr. Billy Higginbotham, Texas A&M AgriLife Extension Service wildlife specialist in Overton, but farrowing, the birth of new litters of pigs, typically peaks in the spring.

Higginbotham said farmers and ranchers in 253 of 254 Texas counties face a constant battle to prevent or reduce damages by wild pigs. The statewide population estimate is around 2.6 million wild pigs, and limited ways of controlling their numbers means they are here to stay, he said.

“Given the population numbers, there’s no way to eradicate them but you can reduce exposure to damage by managing their numbers,” Higginbotham said.

It costs producers time and money to repair damages and deal with the wild pig population, he said. Higginbotham said 71 percent of landowners with pastureland who responded to an AgriLife Extension survey reported damages by wild pigs.

A conservative estimate of statewide damages based on a decade-old study puts the annual cost to farmers and ranchers at $52 million. Producers spent an additional $7 million each year to repair damages and deal with wild pig populations, according to the same estimate.

Wild pigs are omnivores and will seek any food source for calories, Higginbotham said. They cause much of the damages to crops when they dig, or root, for food sources, such as grub worms, planted seed and plant roots.

Higginbotham said the wild pigs are especially damaging to hay pastures in East Texas. Pastures are rooted up and must be smoothed by farmers to allow hay equipment to access the land. Disturbed soil also creates weed control problems, he said.

Landowners should monitor for signs of wild pig activity, such as tracks, rubs against fence posts and trees, well-used trails and hair stuck on barbed-wire fences where they cross, he said.

“If you see the signs of hogs it’s best to take a proactive approach and try to reduce their numbers,” he said. “They may just be moving through your land but eventually they will cause problems. The more you reduce their numbers the more you reduce the damage they cause.”

Higginbotham said there are four legal ways to address wild hogs in Texas – trapping, snaring, shooting and catch dogs.

Hiring professional shooters to reduce wild pig numbers from helicopters represents a cost-effective way for farmers and ranchers in parts of the state with less tree canopy, but in East Texas trapping is advised, Higginbotham said. Corral-type traps work best, especially when a landowner can catch an entire family or sounder of pigs, he said.

But Higginbotham said it takes a process to trap effectively. Pigs must be “hooked” on the bait before placement of the trap, he said. The trap should then be baited to allow the pigs to get comfortable.

“It could take a week, it could take several weeks depending on how much trapping pressure they’ve experienced,” he said.

Higginbotham suggested landowners speak to their local AgriLife Extension agents for tips on what works best in their area to trap wild pigs.

AgriLife Extension district reporters compiled the following summaries:

CENTRAL: Corn planting was completed. About 35,000 acres, or 50 percent, of corn acreage was replanted. Sorghum has been replanted as well. Timely rainfall helped activate fertilizer put out by landowners. Bermuda grass began to emerge. Hay was planted. Cattle were doing well with very little supplemental feeding. Tanks were full and creeks were flowing but there were still long-term concerns about continued precipitation. Crops were growing and cotton was in the ground. Insects have not made a large-scale impact, but rust has been found on some wheat. All counties reported soil moisture and overall range and pasture conditions were good. Livestock conditions were 100 percent “good” as well. Overall, 95 percent of crops were in good condition.

ROLLING PLAINS: It had been a few weeks since the last rainfall and producers were finding the top layers of soil were either dry or drying as they continued preparing fields for cotton planting. There was plenty of subsoil moisture, but the topsoil was problematic. Cotton producers plowed in pre-emergent herbicides. Pastures and rangeland were trying to green up, but without any moisture, the process has been slow. Wildfires have been an issue over the past couple of weeks because there was plenty of fuel and wind to spread fires. Producers have plenty of winter wheat for grazing and livestock were in good condition. There could be a fair amount of wheat baled for feed. Cows were calving in some areas. Some producers were beginning to ship gain cattle, but most said they would wait until May. Some cattle producers were feeding supplement, but only on a small scale.

COASTAL BEND: High winds depleted much of the topsoil moisture. Soil moisture conditions were becoming critically low due to the lack of rain. It had been a month since most of the region received measurable rain amounts. Planted crops needed rain to help roots develop and row crops, hay fields and pastures began to show signs of stress as well. Cotton planting was in full swing and wheat looked good. Corn, grain sorghum and cotton were doing well but suffered due to low moisture levels in other areas. Cattle and livestock were in good to excellent condition. Pecans were leafing out and pecan nut casebearer activity was being monitored.

EAST: Dry, windy conditions were reported around the region. Topsoil was drying out. Most counties reported pasture and range conditions as fair to good with subsoil and topsoil as adequate. Ponds and creeks were full. Farmers were planting vegetables. Jasper County reported crops were doing well with some watering taking place. Application of herbicides and fertilizers to pastures started. Cooler night temperatures slowed warm season forage growth. Winter pastures were looking good. Producers were preparing hay fields for the first cutting. Some producers bailed crimson clover and ryegrass. Livestock were doing fair to good. Some producers stopped supplemental feeding. Spring calving continued along with calf working and sales of cull cows and market-ready calves. Feral hogs continued to pose problems across the area.

SOUTH PLAINS: Producers were in need of moisture throughout the region. Bailey County producers received light scattered rainfall. Sub and topsoil moisture levels in Cochran County have improved with some rainfall received last week. Pasture, range and winter wheat needed rain. Producers continued preparations for spring planting. Floyd County producers needed moisture to help suffering dryland wheat crops. Moisture before planting cotton and corn would also help. Weather was warm and windy. Crop and range conditions were less than ideal in Hale County. Lubbock County experienced light rain of up to one-third of an inch. Isolated rain and hail occurred in the southeast portion of the county. Average minimum soil temperature at 8 inches was up to 56 degrees. Corn planting will begin soon. Field preparation and equipment maintenance was ongoing as planting time approaches. Producers remained concerned about the prospects of a profitable season in light of depressed prices. Scurry County received 0.75 inches. Temperatures were about average. Yoakum County had steady precipitation all day on April 8 and soil moisture increased.

PANHANDLE: Conditions were dry and windy with temperatures near to slightly above average. There was high fire danger as soil moisture levels were mostly short. Producers were actively irrigating. Conditions remained dry in Collingsworth County. Winter wheat looked healthy but needed water. Wheat continued to head out at a rapid pace and was coming along nicely. Conditions in Deaf Smith County were almost perfect for producers. Preparations continued in fields for planting season with center pivots running on wheat fields. Pre-watering on corn fields began in preparation of planting. Wheat was still in a holding pattern with many dryland fields needing water. Irrigated wheat looked good. Silage chopping was expected to start soon. Irrigated triticale was growing well. Graze-out wheat was continually stocked with extra animals to graze down wheat to avoid any forage losses. Hutchinson County was in dire need of rain. Moisture to begin the 2016 crop season was short. Lipscomb County winter wheat was hurting from lack of moisture. Windy, dry weather continued to deplete soil moisture levels and cause wheat conditions to decline in Ochiltree County. Summer crop pre-plant activities continued. High winds prevented herbicide spraying. Cattle on range were still being supplemented. Randall County remained dry. There has been less than 1 inch of rain there since January 1. Corn on pre-irrigated fields was expected to be the only planting done in the near future. Cotton and sorghum acres were not expected to be planted until some type of pre-plant moisture arrived.

NORTH: Topsoil moisture varied from short to adequate with some surplus. Days were warm and nights were cool. Ground temperature was right at 65 degrees. Wind dried topsoil to allow more field work. Bermuda grass greened but was not growing. Winter wheat looked decent across the county. Some fields were inconsistent in growth. Many producers were expected to start baling winter forages soon. Cattle were in good condition. Feral hogs were highly active. Small grasshoppers were out on warm days.

FAR WEST: Glasscock County received two-tenths of an inch of rain. The effects from a slight freeze started to show in some wheat crops. Damage was minor and generally limited to low lying areas. Overall, wheat crops look good. Pre-emerge herbicides were applied to cotton, and planting of sorghum continued. Howard County reported rain but no measurements were available. High winds were reported in Hudspeth County where farmers planted crops. Winkler and Loving counties received 0.25-1.25 inches of rain. Conditions in Reagan County were very dry and high winds caused crop and range conditions to dry up. Farmers in Upton County prepared the fields for planting. Goats and lambs continued to kid. Livestock and wildlife were still receiving supplemental feed. Upton County received rain showers. Across the district pasture and range conditions were poor. Subsoil and topsoil were short and all counties needed rain.

WEST CENTRAL: Dry, warm and windy conditions continued. Light scattered rain showers were reported but were not significant. High winds caused extreme range fire concerns in many areas. All areas needed rain. Field activities continued to increase as planting season began. Weeds continued to be an issue and required control. Preparations for row crops were mostly complete and producers waited for moisture to plant. Producers sowed some spring seeded hay crops. Some cutting and baling of wheat and oats began. Sudan planting started. Grain sorghum was planted but needed additional rainfall to emerge. Winter wheat and oats were planted for winter grazing. Field preparations for cotton planting continued. Winter wheat progressed quickly with the warm, dry weather. However, drought stress was becoming a factor in wheat crops. Wheat conditions were fair to good with some rust showing. A large number of wheat acres continue to be grazed out. Some wheat was harvested for forage. Winter grains were beginning to head out. Range and pastures began to decline due to dry conditions. Forages began to show stress. Winter grasses were still doing well and coming on. Tanks remained in good condition with plenty of water. Livestock remained in fair to good condition. Cattle prices held steady.

SOUTHEAST: Weather provided excellent growing conditions for warm-season plants in Brazos County. In Fort Bend County, most producers had planted crops but needed rain. Livestock were in good condition throughout the county. Hay producers cut winter ryegrass remnants to promote warm-season forage growth. Soil moisture levels throughout the region varied widely. Most levels were adequate to surplus with adequate being the most common. Rangeland and pasture ratings varied widely too, mostly from excellent to good, with good being most common.

SOUTHWEST: Recent rains helped forages, and spring growth of grass and wildflowers. Pecan trees continued to leaf out, and hay producers shredded winter weeds and prepared to fertilize hay fields and pastures. Livestock remained in good condition. Spring shearing was underway.

SOUTH: Temperatures began to rise, with cool nighttime temperatures and no rainfall was reported in any counties. Mild temperatures were reported in Atascosa and Brooks counties. The majority of crops in Frio County were being irrigated. Potato crops were in the flowering stage in Frio County and the majority of wheat and oats were headed. Sorghum and corn were completely planted and corn was emerging. Cotton planting began. In Live Oak County, conditions were good for field activities and crop spraying as winds calmed enough to prevent a drift. Topsoil moisture conditions declined in McMullen County. Dry-out could impact further range and pasture improvement until topsoil moisture levels improve. Range and pasture conditions remained fair to good in McMullen and surrounding counties. Body condition scores on cattle remained good. Soil moisture conditions were 98-100 percent adequate in Atascosa County, 50 percent adequate in Frio County, 80 percent short in Live Oak County and 70 percent adequate in McMullen County. Pasture conditions were average in Brooks County. Fog and mist provided some moisture, but the lack of rainfall took its toll. Livestock prices remained steady. In Jim Wells County, weather conditions were favorable for field work. Row crop producers progressed well with planting crops. Some producers finished planting, and a few hoped to be done soon. No significant rainfall was received in the last few weeks, but some rainfall was forecast. Range and pastures throughout Jim Wells County were good and improving. Livestock conditions were good. The local cattle market experienced a five cent drop in 500-pound steers as compared to the previous week. Offerings and demand remained steady. In Kleberg and Kenedy counties, temperatures were cooler than normal. Soil moisture conditions were 100 percent adequate in Brooks and Jim Wells counties and 70-75 percent adequate in Kleberg and Kenedy counties. Maverick County did not receive rainfall and temperatures reached 80 degrees during the day. Nighttime temperatures continued to be quite cold. Crop farmers continued to plant but most have already finished. Pecan orchards started to turn green and look healthy. Also in Maverick County, Coastal Bermuda grass was ready for the first cut. Producers will make either round or square hay bales. All wheat and oats were maturing well across Zapata County. Early reports from producers indicate yields should be average or a little better compared to last year. Native range and pastures continued to provide adequate forage for grazing livestock and no supplemental feeding was reported. In Zavala County, corn, sorghum, carrots and onions made good progress following irrigation. No insect pressure was reported on any crops. Soil moisture conditions were 35-50 percent adequate in Dimmit County, 70 percent short in Maverick County and 100 percent short in Zavala County. Range and pasture conditions continued to improve with recent rainfall in Starr County. Spring vegetable crops were also progressing well and soil moisture conditions were 90 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.
