I had a client call suggesting I make the following changes to our insect treatment thresholds to make things a little easier. I added the last one myself. Continue reading
I’ve had a few calls from the Mississippi River Bottom about armyworms in soybean and even in some Bt cotton. I’ve also had a few people complaining about a lack of control with insecticides and the fact that larvae were eating pigweed and then moving into the crops. This is a pretty good sign you are dealing with beet armyworm (as opposed to fall armyworm). Continue reading
It’s the time of year where soybean insects are much more likely to cause us problems, and it is important to vigilantly scout. Although stink bug populations are behind schedule, they are becoming more common. I’ve received numerous questions about a complex of pests including Continue reading
I’m just putting the word out to report any finds of brown marmorated stink bug (BMSB). This is especially for those located in the western one-half of the state.

However, Continue reading
