ABSTRACT:
A liquid herbicidal composition is disclosed which retains its penetrating and systemic activity after application to susceptible flora under normal ambient conditions for a period of at least six hours by combining at least two different salts of at least one herbicidally active compound and a polyhydric alcohol having 2 to 6 carbon atoms. The salts are preferably amine, ammonium or alkali metal salts of herbicidally active acid halogenated phenoxy acids. The herbicidal composition upon application to noxious vegetation has the unexpected property of retaining its phytotoxic activity throughout the maximum residence time necessary for effective weed and brush control by virtue of the fact that the composition resists crystallization and displays no tendency to either burn or otherwise damage the external cellular layers of the plant being treated.
