One of the daily headaches applicators deal with on a regular basis — sometimes multiple times per day — is the need to flush out tanks and equipment between types of pesticides and herbicides. In recent years, weed resistance has made this chore more frequent. Farmers could put glyphosate in the tank and go from field to field, whether it was on corn or soybeans. Now, each field and crop may require a different herbicide, depending on the crop and the type of weed resistance. That means more time returning to home base and rinsing, mixing, and refilling the tank.
Direct injection can make life a lot easier by reducing time spent on these tasks. With direct injection, the pure liquid chemical is injected into the main stream of a liquid application. The tank is filled with water only, and the chemical is added as it is sprayed onto the field. Gary Esselink, Precision Ag Specialist/Product Manager at Raven Applied Technology, outlines a number of advantages direct injection systems have in today’s crop systems.
