A quick update this week. There are no major insect issues occurring on a widespread basis. Call about plant bugs indicate variable and average infestations in cotton. For cotton close to or in early bloom and requiring treatment for plant bugs, it would be a good time to consider getting some Continue reading
Catchy title eh? No major insect problems are occurring on a wide basis, but the phone is ringing more frequently about several issues. Continue reading
Good early-season management of tarnished plant bugs relies on a sweep net, monitoring square retention, and making timely insecticide applications as needed. During the first two weeks of squaring, the recommended treatment threshold is an average of 8 or more plant bugs per 100 sweeps. After that, treatment is recommended anytime of infestations average 15 or more plant bugs per 100 sweeps Continue reading
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.
The UT Cotton Scout School is scheduled for the last Friday of the month, May 31st, at the West Tennessee Research and Education Center (605 Airways Blvd, Jackson).

With limited crops emerged, it is not too surprising that I’ve not been getting many calls about pest problems. The most frequent calls are listed below, along with some management tips and some photos. Continue reading
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
Below is a synopsis of take home points about insect management that I tried to make during the winter meeting season. Obviously, I’ll get into many of the topics in greater detail as the season progresses, but here is some food for thought. Continue reading
