Although current moth activity remains relatively low, I’m expecting a peak of moth activity sometime beginning around August 5th through 10th. Bollworm (a.k.a., corn earworm) poses a significant threat to cotton and soybean, and particularly late planted soybean that are still flowering when the flight arrives. Below are some thoughts on managing for this troubling pest. Continue reading

The treatment threshold for tarnished plant bug beginning at first flower is 3 tarnished plant bugs per drop cloth. You should maintain this threshold until about NAWF5+250 DD60s, at which time Continue reading
Although pressure is currently below average, it is increasing, which is to be expected as we enter the early blooming window. We have limited but good options to control plant bugs in blooming cotton. I often tell folks that if you call me once bloom starts, I’ll often only mention 4-5 products, sometimes in combination. Those include Acephate/Orthene, Diamond, Transform, and Bidrin. Vydate also gets and honorable mention. These are the core products suggested for mid-season plant bug control. Below are some treatment options I like, in no particular order. However, Continue reading
A reminder that moth trap catches are reported weekly for corn earworm (bollworm), tobacco budworm, and southwestern corn borer. You can find these data under the Quick Links menu of this web site which takes you to the link below.
We are also seeing an increase in bollworm moth catches. I’m hopeful many of these moths will target later corn rather than cotton or soybean, but Continue reading
