Corn Herbicide Premixes

Each year, several "new" corn herbicides become commercially available. Some of these new options contain novel active ingredients, while others are premixes of preexisting active ingredients or different ratios of earlier premixes. Table 2 lists many available corn herbicide premixes, which active ingredients and how much of each are contained in these premixes, a common field-use rate, the amount of each active ingredient applied at that use rate, and finally a column of tank-mix equivalents. A similar table for soybean herbicide premixes will follow in a few weeks.
