COLLEGE STATION – Disease problems for vegetable producers and gardeners are popping up around the state, according to a Texas A&M AgriLife Extension Service expert.

Conditions have been good for vegetable production around much of the state following mild spring conditions and ample rains, but the weather is also setting the stage for plant diseases, said Dr. Kevin Ong, AgriLife Extension plant pathologist and director of the Texas Plant Disease Diagnostic Laboratory in College Station.
Ong said producers have been seeing early blight, a fungal pathogen, in tomato plants. Symptoms of early blight include yellowing of bottom branches and blotches on leaves.
Hot, drier conditions recently could allow another threatening fungal pathogen to affect vegetable gardens and fields, he said.
“It’s getting hotter, so I am predicting that with all the early moisture, I would not be surprised to see an increase in southern blight incidence,” he said.
Southern blight infestations can infect a variety of vegetables including squash, tomatoes and zucchinis, Ong said. Symptoms include white fungal growth visible at the base of the plant. Plants quickly wilt and die from the disease, while the root system often looks normal. Go to http://bit.ly/2rUZHJF for general information, and see http://bit.ly/2tcuLrH for information on tomatoes.
There are not many effective treatment options available for home vegetable growers to deal with southern blight, Ong said.
“The best thing you can do is sanitation,” he said. “The fungus sclerotia can survive in the soil, so cleaning up your garden area well and getting rid of diseased plants as soon as they show symptoms is a good idea.”
Solarization, a practice of using plastic to cover moistened, tilled soil to increase the temperature, can help reduce sclerotia numbers. Sclerotia is a plant fungus and can cause white mold if conditions are conducive. Sclerotia can be killed in four to six hours at 122 degrees. Amending soil with compost or organic matter can help reduce southern blight incidence by encouraging growth of biological antagonists. The biocontrol agent Gliocladium virens has also been shown to suppress Sclerotium rolfsii, he said.
AgriLife Extension district reporters compiled the following summaries:
CENTRAL: Field work continued, including spraying cotton for insects and baling hay. Corn silage harvests were going full speed in some areas, while other producers expected to harvest within three weeks. Yields and quality looked good. Grain sorghum was progressing well with some coloring. Sugarcane aphids were not an issue so far this year. Grass conditions were excellent. Some brush work was done. A significant amount of rain fell and caused flooding in some areas. Tanks and other bodies of water were full. Cattle and other livestock were in great condition, however fly numbers on livestock increased. Nearly all counties reported good soil moisture and good overall crop, pasture and rangeland conditions.
ROLLING PLAINS: Conditions remained hot and dry with no moisture. Pastures and rangelands took a turn for the worse. In some counties, pastures were drying out to the point wildfires were becoming a serious threat once again. Livestock were in good condition. Producers began feeding supplements to cattle on a regular basis to avoid selloffs. Plantings of this year’s cotton crop were almost complete, but the outlook was bleak due to poor moisture levels. Most cotton acres either haven’t emerged or emerged only to be scorched by hot, dry, windy conditions to the point plants were dying. Cotton that tapped into deep moisture seemed to be doing well, but a good general rain was needed to keep it going. Some producers started spraying mesquite.
COASTAL BEND: Most crops needed moisture, but rain was scattered and may slow the start of harvest in some areas. Early planted corn was drying down rapidly with some rust present. Grain sorghum was coloring with some combines running. Sorghum yields were good thus far, but some producers were concerned with head sprouting, lodging and harvest delays. Cotton was in full bloom, but some cotton had worms. Fertilizer applications were made on hay fields in anticipation of additional rain, and some weed and brush control applications continued. Pastures and livestock continued to do well, however large fly numbers were reported.
EAST: Tropical storm Cindy produced heavy rain in several counties around the region while other counties only received light rainfall. Jasper County reported some wind damage to corn. Subsoil and topsoil conditions were adequate in all but Shelby County, which reported surplus. Cherokee County reported ponds and creeks were full. Pasture and range conditions were good in most counties. Hay baling was slowed due to the rain. Some producers were getting ready for their second hay cutting. Wood County reported armyworms due to recent rains. Wild pig damage remained a problem in hay meadows, pastures and corn, and control was underway in Upshur County. Corn fields in Anderson County were 100 percent dented. Grain sorghum looked good and was heading out with no aphid control needed. Vegetable crops including purple peas, tomatoes, okra and beans were harvested and sold at local markets. Watermelon growers reported high yields and good quality. Cattle were in good condition. In Anderson County, the cattle market was weaker on some classes including cow/calf pairs and bred cows. Feeder steers and heifers ended $3-$7 per hundredweight lower. Slaughter cows finished steady with slaughter bulls ending $1 per hundredweight higher.
SOUTH PLAINS: The district experienced another week of temperatures in the high 90s with gusty winds and some rain. A cool front passed through the area. Showers should help improve subsoil and topsoil moisture conditions, but rain was desperately needed. Some dryland fields were released by insurance adjustors. Other dryland fields had thin or skimpy stands. Wheat harvests were almost wrapped up, and farmers were lucky to avoid major storm events to affect the harvest. Peach harvests were ongoing. Cattle were in good condition.
PANHANDLE: Many parts of the district remained extremely dry, with excessive heat for most of the week. Strong winds over the last few weeks took a toll on soil moisture conditions. Crops were beginning to suffer and it was slowing plant growth. Wheat harvest continued and should wind up by July 1. A few scattered showers halted harvest in the northern part of the district for a day, but hot, dry conditions were the standard. Corn, sorghum and soybeans were being irrigated. Cotton irrigation was expected soon. Dryland grain sorghum was still being planted in some counties. Range conditions declined with the dryer, hotter weather, but pastures overall were in good shape. Cattle were in good condition with fly control occurring. Respiratory complications in some cattle were still being found in the northeastern part of the district due to the March 6 wildfires.
NORTH: Topsoil and subsoil moisture levels ranged from mostly adequate to short with a few counties reporting surplus. This week brought some much needed rain to North Texas with amounts ranging from 1-3.5 inches around the counties. Corn and soybeans were doing well. Cotton was up and looking nice. Wheat and oat harvests were finished with yields averaging 50 bushels and 70 bushels per acre, respectively, and near-average weights on both. Pastures and livestock were in very good condition, and spring-born calves looked good. Insects were beginning to be a problem on livestock with heavy fly and mosquito numbers in some areas. Feral hog activity was moderate with 16 hogs caught in demonstration traps during the reporting period.
FAR WEST: Temperature highs were in the 110s with lows in the 70s. Rainfall totals were near 1 inch. Winds damaged trees and power lines. Lightning damage was reported. Rains came at a critical time for dryland cotton, which was in desperate need of moisture to help establish root system and some fields emerge. Sorghum was in the boot stage or blooming and needed a good rain. The rain supplemented irrigation for all crops. Pastures were very dry, so many ranchers were providing supplemental feed for cattle and reduced their stocking rates to conserve forage. Producers began to ship lambs and kids. Rabbits and deer were moving into cotton and sorghum looking for something green to eat. Pecan trees and fruit trees were faring well but needed irrigation.
WEST CENTRAL: Conditions were hot, dry and windy. High temperatures were in the triple digits most of the reporting period, but cooled down some. Soil moisture was declining rapidly due to extreme temperatures. Home gardeners were pulling the first harvest of fresh vegetables. Wheat harvests were complete in most areas. Cotton planting continued. Cotton fields were beginning to emerge and looked good. Haygrazer fields were in excellent condition and hay reports were good. Cutting and baling was underway. Grain sorghum was in mostly good condition with some fields showing some heat stress. Rangeland and pasture conditions were mostly good. Some grasses and forages were starting to show signs of heat stress and will need rain soon to make it through the summer. Most stock tanks were full. Livestock remained in fair to excellent condition. Markets remained strong in most areas. Cattle prices dropped in some areas with the number of head at auction also down. Pecan crop reports ranged from very good to poor.
SOUTHEAST: Most counties received showers to heavy rains from Tropical Storm Cindy. More than 3 inches of rain was reported in northern Lee County. Walker County was concerned with soil moisture due to evaporation from heat. Montgomery County experienced moderate temperatures. A few showers promoted good growth in pastures and new growth in trees. A few insect pests were present but not to the extent of serious damage. Rangeland and pasture ratings varied from excellent to good with good ratings being the most common.
SOUTHWEST: Available forage was suffering due to the lack of rain. Some areas received rain but the amounts did not help much and rivers were beginning to dry. Rangeland was starting to dry and grasses showed signs of dryness. Temperatures continued to rise and producers were cautious of working during the heat of the day. Fly populations continued to increase. Livestock were in fair condition.
SOUTH: Conditions were hot, dry and windy. Temperatures were soaring well above 100 degrees throughout the district. Rangeland and pastures continued to show signs of stress and fire hazards increased. There were some spotty showers across the northern portion of the district and temperatures cooled from 105 to 90 degrees as a result. Rainfall amounts ranged from 0.2-0.5 of an inch. Potato and sweet corn harvests continued and were nearing completion. Corn fields were maturing. Sorghum fields were turning color and cotton fields were setting-bolls. Pasture and rangeland conditions were beginning to dry. Soil moisture conditions were very short and body condition scores on cattle remained fair despite the harsh summer conditions. The live cattle market remained was steady. Livestock offerings at the local Jim Wells County auction fell below 500 head for the first time this year. Prices were steady with 500-600-pound steers averaging $132 per hundredweight. Wildlife habitat throughout Jim Hogg County was in good condition with good numbers of deer, quail, dove and turkeys reported. Grain harvests were in full swing. Corn and cotton were irrigated. Native rangelands and pastures continued to provide adequate grazing for livestock, but the forage quality was beginning to diminish. No supplemental feeding was reported. Hay was being baled.

Grazing North Texas: Who’s Your Neighbor?
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
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
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.
