Some reports have come from folks concerned by the lack of Palmer amaranth response to applications of dicamba plus glyphosate applied in the last 10 days. I expect to get more of these calls as I have seen similar results in our research this spring. Continue reading
UT Weed Tour Cancelled

It is especially important that our late planted cotton gets off to a good start to make up for a little lost time. Unfortunately, the ‘Thrips Infestation Predictor for Cotton’ (https://climate.ncsu.edu/cottonTIP) appears to be dead on in predicting our heaviest thrips pressure will occur in early June, just as our later planted cotton is most susceptible. I’d suggest making an insecticide application to Continue reading
