A new publication has been released detailing the 2015 planted acreage for corn, cotton, grain sorghum, soybeans, and wheat in Tennessee by County. To review this publication go to 2015 Planted Acreage in Tennessee.

Although stink bug populations remain generally light, there are now some reports of populations exceeding the treatment threshold of 9 per 25 sweeps. Remember you should probably double this threshold once a field reaches R6. Calls are also trickling in about defoliation Continue reading

First, I’ll refer you to a good article from Mississippi State University from last week. This article also addresses if, when, and what harvest aids can be applied. Continue reading
