The advanced Drillkote brand line of soybean treatments is designed to allow easy identification of the level of seed treatment protection. Bronze through Gold offer protection levels from soil born disease protection, disease and insect protection, to both of those plus inoculation. We are introducing two new treatment options this year, Drillkote Nutrient and the effective nematicide BIOST.
Our goal is a no-nonsense, convenient treatment ordering system. Soil type, weather, and management practices all play a role in which level of treatment you need this year. From untreated to Drillkote Gold and beyond, we have you covered!
