After harvest is the perfect time to take soil samples not only for nutrient analysis but also to look for pathogens. You’ll never know if you have silent yield robbers lurking in the soil unless you look for them – Take the test, beat the pest!
Reminder to come see varietal and fungicide differences as well as training on disease and insect identification and management at the Milan Research and Education Center on Sept. 3 – registration is at 8:30 with tour beginning at 9, concluding with lunch.
For the last couple of weeks I’ve been getting asked about leaf spots in cotton and the majority of them have been leaf spot complex.

Wheat is in bloom and when considering a fungicide application one needs to assess their risk for fusarium head blight (FHB) or head scab infection. Continue reading
