UT’s Soybean Scout Schools will be held in July (see below). Additional details will be posted as they become available. These field-side programs cover the basics of soybean growth, scouting, pest identification, and general management. Pesticide recertification and CCA CEU points will be available. Scout Schools are offered free of charge with sponsorship from the Tennessee Soybean Promotion Board. Registration is not required. Participants will receive a scouting notebook and a sweep net while supplies last. 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). There is no fee, and preregistration is not required. Registration begins at 8:00 AM with the program starting at 8:30. Content will include classroom and hands-on training with an optional ‘go-to-the-field session’ after a box lunch. Topics covered will include cotton development and identification and symptoms of insect pests, plant diseases, and weeds.

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
Once again, the TDA and EPA have approved the use of Transform WG in cotton for the control of plant bugs. Hopefully, this will be the last year a section 18 request will be needed, pending a new label for this product.
