Herbicide Premixes for Corn

Each year, several "new" herbicides appear on the market. Someactually contain new active ingredients, while others are actually premixesof two or more existing products. It can be confusing, attempting to rememberwhat components make up a premix, let alone trying to remember how muchof each component is contained in a field-use rate of the premix. Table4 contains information on the premix herbicide products currently availablefor use in corn. A table with similar information for soybean products willfollow in a subsequent issue of this Bulletin.
