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.
- Preharvest Interval: Do not apply within 14 days of harvest.
- Minimum Treatment Interval: Do not make applications less than 5 days apart.
- Do not make more than four applications per acre per year.
- Do not make more than two consecutive applications per crop.
- Do not apply more than a total of 8.5 oz of Transform WG (0.266 lb ai of sulfoxaflor) per acre per year.
This labeling must be in the possession of the user at the time of application … Section 18 Label Transform WG – Cotton
The Tennessee Department of Agriculture and the EPA has again approved a Section 18 that allows the use of Sivanto prime on sweet sorghum for the control of sugarcane aphids during 2019. This pest is potentially devastating for those growing sweet sorghum for molasses or other uses, and Sivanto prime is an excellent any the only available insecticide option in this crop. Specific requirement for it’s use are summarized below and detailed in the Continue reading
One of the most consistent yield responses I’ve seen in my time at UT is when a foliar insecticide application is made to wheat at this time of year (late January – late February). An insecticide application, specifically a pyrethroid insecticide, has increased yield by an average of over 5 bushels/acre. Thus, this application has become a fairly routine recommendation. Insecticides can be co-applied with a herbicide or Continue reading

I ran a post last week that somehow got lost in cyberspace, so this is my effort to recreate it.
Cotton: The gist of my post last week was that most early planted cotton has accumulated more than 350 DD60s past NAWF5, and thus, insect management was Continue reading
Cotton: Much of our cotton is within 7-10 days of when insect controls can be terminated, and it looks like this cotton may outrun the bollworm moth flight in many areas. Most the bollworm action appears to be pretty moderate and still primarily concentrated along the Mississippi River and south of I-40. Having said that, we are some seeing bollworm larvae slip through on Bollgard 2, WideStrike, and TwinLink varieties. It’s a numbers game. Continue reading
