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


Some take home points about insect control from the winter meeting season

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

Sugarcane aphids

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

Cotton and Soybean Insect Update

Author:  Comments Off on Cotton and Soybean Insect Update

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
