Insecticide Concoctions for Plant Bugs in Blooming Cotton

Author:  Comments Off on Insecticide Concoctions for Plant Bugs in Blooming Cotton

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

Corn earworm (bollworm) moth

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

Tarnished plant bug (adult)

It’s been a generally quite week for insect problem but below are some reminders and suggestions.

Cotton:  Most cotton is past the stage where thrips are a concern.  Tarnished plant bugs will now be our primary focus for much of the season. Thus far, most reports indicate a slow and sporadic start with plant bugs, but treatments are now being made more widely.  However tempting, I encourage people to avoid using Continue reading

Note the abscission scar left by shed square at the second position fruiting site

Below are a few reminders as much of the crop will begin squaring in the next week. It’s too soon to know what kind of plant bug year we will have, but there are a couple of truism that generally hold. When we have a wet spring, and particularly a cool spring, infestations in cotton often start a little later than normal. The weedy hosts of tarnished plant bug will stay attractive longer, holding the bugs longer before they migrate into cotton. However, we often since higher than normal populations during mid and late season under the same circumstance. Second, Continue reading

SWCB moth

Just a reminder that moth trapping data are collected weekly and reported on this website under the Quick Links menus (http://www.utcrops.com/BlogStuff/2020MothTrappingData.pdf). Moth catches of bollworm (corn earworm) and tobacco budworm are low, typical of this time of year.  However, southwestern corn borer traps in some areas are pretty high. For those with non-Bt corn, this is a cause for concern in those areas (and perhaps others). This first generation will be found feeding within whorls until they begin stalk tunneling. You can read more about their management by Continue reading
