Interactions among the components of an herbicidal solution may take place (a) in the solution itself, (b) at the plant surface or within tissues to influence absorption and translocation, and (c) at the cellular site of toxic action. This broad meaning of the term interaction is employed in the present report. Similarly, the meanings of antagonism and synergism are considered as inhibition and enhancement, respectively, of the toxic action of one substance due to the influence of another, regardless of the location and nature of the interaction.
