Bird Cherry-Oat Aphids have been seen in low numbers on wheat across Hill county. Many beneficial predators (ladybugs, lacewings, ect) have also been seen and will help keep the aphid populations in check. Hessian Fly has also been observed in low numbers. Both of these pests are more significant in the fall, but large populations can still cause damage.
Wheat rust may begin to emerge soon due to last week's rain. If you have planted susceptible varieties, monitor your wheat carefully. A fungicide application may be warranted on susceptible varieties as rust pustules move up the plant to the newer leaves. Protecting the flag leaf is essential to maintain yields. There are many factors that go in to making decisions to spray fungicides for diseases on wheat, such as price of wheat, expected yield in that field, variety susceptibility, future weather conditions, and more.
