There have been only a few calls concerning soybean insect problems. Mostly what is being reported is sub-threshold infestations of stink bugs, green cloverworm, a few remaining Japanese beetles, and kudzu bugs in some areas.
The second generation flight of kudzu bugs has been active for the past couple of weeks. I’ve observed treatment level infestations in some fields in east Tennessee and in the Memphis area.
As soybean fields in Tennessee reach reproductive growth stages, scouting for disease is critical to determine how necessary a fungicide application may be in protecting yield from disease. The effect on yield from a disease are closely associated with environmental
There has been some discussion about how to manage Palmer amaranth next year in light of the likely PPO-resistant Palmer amaranth in the picture in some fields. Utilizing Liberty Link soybeans is a good option but seed supply in my
Timely applications of recommended rates of Flexstar did not control Palmer amaranth in two fields in West Tennessee. So Palmer amaranth samples were taken from these fields and sent to the University of Illinois to test for PPO herbicide resistance.

Many cotton acres are nearing the true “laying it by” application timing. Given how Palmer amaranth just keeps coming this year these directed applications have become critical for consistent control of glyphosate-resistant (GR) Palmer amaranth. Ten years ago a typical post-direct
Sugarcane aphids have now been confirmed in Shelby County. The good news is that populations are very low at this time, and it seems to me that we are on a similar schedule as last year. Thus, I’m hoping that much
The subject of plant population is a constant source of debate in all crops. On one side of this discussion are the seed companies that want to market more of
