Herbicidal composition

Abstract

A herbicidal composition in the form of an emulsifiable concentrate which comprises, in addition to emulsifiers and water-insoluble solvents, 2,2-dimethyl-propionic acid 8-(2,6-diethyl-4-methyl-phenyl)-9-oxo-1,2,4,5-tetrahydro-9H-pyrazolo[1,2-d][1,4,5]oxadiazepin-7-yl ester and an alcohol.
