Corn protection program
Corn protection program from field preparation to harvest: herbicides, seed treatment, starter nutrition, micronutrients, insecticides against European corn borer and cutworms, fungicides and desiccation. The program is built by active ingredient; rates are given for a product with the stated a.i. content. Our agronomist will select specific products from the catalog.
