Corn Maturity Cutoffs for Herbicides

May
2021
How large can corn be before glyphosate could potentially cause injury? The glyphosate label states it can be applied up through the V8 corn growth stage. My experience has been if glyphosate is applied to corn larger than that it can at times cause ears to be barren. This phenomenon is difficult to predict ahead of time as it can vary due to maturity of the corn at application, hybrid and weather. Continue reading

Using the Thrips Infestation Predictor for Cotton

May
2021
A reminder the Thrips Infestation Predictor for Cotton described in the article below, published last year, is still available for use. However, the link has changed to https://products.climate.ncsu.edu/ag/cottontip/.
———————————————————————-
The Thrips Infestation Predictor for Cotton is a useful tool for predicting whether a foliar insecticide application is needed for thrips control in cotton. It uses local weather data in association with a user defined planting date to estimate the size of the local thrips population, the susceptibility of seedling plants, and thus, the risk of thrips injury. The model is for tobacco thrips, by far the most common species infesting cotton in Tennessee. Continue reading

The call of the week is how to control ryegrass and, in a few other cases, fine fescue in emerged corn (Video of ryegrass and fescue in corn). Several have reported these grasses recovering from glyphosate + dicamba or in a few instances, glyphosate + rimsulfuron burndown. The questions that follow are why did they recover and what is the best way to control them now that the corn is up? Continue reading
