Dr. Calvin Trostle, Extension Agronomy, TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101, ctrostle@ag.tamu.edu;   Wheat Conditions in Texas As you too well know conditions across most of Texas have gradually turned dry and worse into extreme drought (Fig. 1).

Dr. Calvin Trostle, Professor & Extension Agronomist/AgriLife State Hemp Specialist, TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101, ctrostle@ag.tamu.edu Dupont’s popular insecticide Prevathon is now a product of FMC.  The use instructions for crops and pests are essentially the same.  The percentage of active ingredient ‘RynaXypyr’, or chlorantraniliprole, is much different.  This leads to large changes in the labeled application rates.  Prevathon was 5.0%, Vantacor is 47.85%.

IWM entails cultural tactics such as crop rotations, adjusting seeding rates, planting cover crops between cropping seasons to suppress weed emergence, minimizing weed seed rain through harvest weed… Read More →
