By Dominic ReisigEvery year, entomologists from the National Cotton States Arthropod Pest Management Working Group are polled on insecticide efficacy. This group consists of university Extension entomologists across the Cotton Belt. The ratings are based on experience of those in the group and, from my perspective, are relatively accurate. Each entomologist is asked to rate the insecticide from 0 to 10, with 0 = not effective and 10 = completely effective.

By Dominic ReisigI call the first week of September looper week, and this year has not disappointed. Soybean loopers cannot overwinter in North Carolina and migrate yearly from the south. The adults show up in late August and lay eggs that develop into larvae that feed on soybean leaves in early September. This recent article details their biology, why they are frustrating to control, and some insecticide recommendation. Here is an updated table of efficacy.

These were a major concern for growers and still are, outside of areas that knock them out with treatments for tarnished plant bug. Growers who have followed our regional insecticide recommendations for tarnished plant bug should not have sprayed a broad-spectrum insecticide yet, outside a possible early-season thrips spray.

By Dominic ReisigFor many years, corn earworm has been the top pest in North Carolina soybeans in terms of cost of control and losses. Corn earworm is primarily a later-season pest and more common in later-planted soybean. The reason for this is that local populations build up in their primary nursery crop, corn. They pupate in the soil, emerge, and infest soybeans that flower in late-July and August. However, corn earworms also migrate from more southern areas.

A lot of growers, curious about how their corn might have pollinated after this period of intense drought, have found corn earworm in their Bt corn. What gives? We have documented corn earworm resistance to all hybrids with Cry toxins since 2016- eight years now.
