Managing Early Season Plant Bugs in Cotton

Good early-season management of tarnished plant bugs relies on a sweep net, monitoring square retention, and making timely insecticide applications as needed.

After that, treatment is recommended anytime of infestations average 15 or more plant bugs per 100 sweeps Continue reading


Moth Trapping Data

Corn earworm (bollworm) moth

A reminder that moth trapping data are updated weekly at http://www.utcrops.com/BlogStuff/2019MothTrappingData.pdf, and you can also access these data on the Quick Links of this site.  Pheromone-baited traps are run for corn earworm (bollworm), tobacco budworm, and southwestern corn borer.

With the exception of some notable hotspots for southwestern corn borer, moth trap catches are generally low, as typically observed this time of year.

A Reminder About Armyworms

Author:  Comments Off on A Reminder About Armyworms

Each year, about this time, I end up writing essentially the same article. There have been a couple of reports of armyworms in wheat. Nothing crazy but much of the wheat is still in the milk stage and would be susceptible to excessive defoliation. Occasionally, armyworms may even cut the heads, typically when populations are high. Yield loss is most likely if defoliation occurs during the milk stages, with Continue reading
