As full season soybeans 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. Continue reading
Frogeye leaf spot (FLS) has begun to show up in susceptible varieties in Tennessee, but there is also some chemical burn in soybean that can be mistaken for FLS. Continue reading
UT’s annual Soybean Scout Schools are set for the dates and times below. These field-side programs last 2-2.5 hours and address general crop management including plant development and management of weed, disease and insect pests. As always, scouting supplies and sweep nets are Continue reading
Many of our treatment thresholds for defoliating pests in soybean are based on percent defoliation and growth stage. This is an important component of our IPM recommendations because we are often dealing with a complex of pests, many of which nibble on leaves. This includes bean leaf beetles, Japanese beetles, and several Continue reading

HEAVY RAIN SHOWERS IN SOME AREAS, GENERAL RAIN NEEDED IN OTHERS
Persistent rains over the past two weeks are now showing advantages through steady development of crops, though the cotton crop would benefit from more heat units. Steady rains kept some producers out of the field for a time, but diminished enough for wheat harvest to be completed in a few areas. Continue reading at Crop Progress 7 6 14 .
Our trap lines are indicating low moth activity for corn earworm, tobacco budworm, and southwestern corn borer (link to Excel file). In moth traps this last week, we only caught an average of 7 corn earworms (a.k.a., bollworms) and less than 1 tobacco budworm and southwestern corn borer per trap. Continue reading
I recently posted an article about being on the watch out for fall armyworm infestations in soybean (link here). This is especially important to think about anytime in the next several weeks if grassy weeds are common in a field. However, this also indicates a potentially early start in pastures, and be especially watchful in Bermudagrass. It seems early, but it appears fall armyworms are Continue reading
Unfortunately, due to the weather some soybean fields ran out of residual some time back and post applications have not been able to be applied timely. The question is how we proceed from here? Continue reading
