Premix ratios

Many pre-emergent corn herbicides are a combination of a grass and a broadleaf product. Atrazine is a common broadleaf product used in pre-emergent herbicides. Atrazine rates are regulated by the government so it is important to know the amount of atrazine contained in a premix herbicide when determining the correct application rate. Try out our premix ratio calculator to determine the amount of grass and atrazine product contained in the following herbicides.
