Abstract
A novel herbicidal method is provided wherein plants are first treated with a glyphosate herbicide and then sequentially treated with a liquid accession agent which provides improved herbicidal effectiveness such that plants are controlled with lower rates of the applied herbicide. Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that may be exhibited when the accession agent is added to the herbicide in a tank mix or coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain silicone-based and fluorocarbon-based surfactants.
