Most everyone is aware that bollworms are not as susceptible as they once were to several Bt toxins present in cotton. Specifically, resistance monitoring across the Mid-South and spearheaded by Dr. David Kerns at Texas A&M University indicates that the bollworm has developed some level of resistance to the Cry1 and Cry2 toxins present in WideStrike, TwinLink, and Bollgard 2 cotton varieties. So the obvious question is what to do about it. Continue reading
Our options for thrips control in Tennessee are mostly unchanged, but there are some key points you should remember. Imidacloprid is the only base insecticide seed treatment that, in my opinion, you should consider. In reality, it is the only base insecticide treatment being sold in our area. Adding other seed treatment components MAY reduce the need for foliar insecticide applications for thrips control, depending on what it is. This can reduce the likelihood of needing a foliar application for thrips. This can be important because NO INSECTIDICIDES are approved for tank mixing with applications of any dicamba products in cotton. Continue reading

A new web-based field guide for soybean insects has been launched. This site performs like an ‘app’ wherever you have cellular service and provides general information about common pests, suggestion for samplings, recommended insecticide treatment thresholds, photos, and management recommendations (including insecticide selection).
This site is complimentary of the cotton insect field guide and disease guides for soybean, cotton and wheat developed by Dr. Heather Kelly. You can access the “UT Disease and Insect Field Guides” directly at http://guide.utcrops.com/ or from the menu on the UTcrops News Blog at http://news.utcrops.com/.
Tip – Save the UTcrops News Blog website to the home screen of your Android, iPhone or iPad to have app-like access to content including this news feed, the above field guides, UTcrops.com, and other content.
