This is a repeat of an article from last year (as a reminder). 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 5.7 bushels/acre. Thus, this application has become a fairly routine recommendation. Insecticides can be co-applied with a herbicide or Continue reading

Insect Control … last week for cotton … not so much for soybean

Author:  Comments Off on Insect Control … last week for cotton … not so much for soybean

Based on average historical temperatures, the last effective bloom date was two week ago.  A late flurry of bollworm moth activity has forced some sprays this week, and most folks are electing to Continue reading
