2020 Field Corn Hybrid Herbicide Tolerance Information (Prostko)

Some good information to keep in your truck about the tolerance/sensitivity of field corn hybrids to certain herbicides. A very good idea for field corn growers to check this information BEFORE an herbicide application is made.

A = Acceptable: Either no adverse effects from the corn product/herbicide combination were noted on any traits or only slight damage could be noted under adverse conditions or herbicide application at higher than label rates. C = Caution:  The corn product/herbicide combination is usually not a problem if sprayed according to label directions, but can result in plant height reductions, stand loss and suspected yield loss under very adverse environmental conditions, high rates or extreme soil pH levels or organic content. Use drop nozzle spraying for postemergence herbicides to avoid interactions. W = Warning: Not advised–this corn product/herbicide combination should not be used under any circumstances.
