Claims18
A herbicidal composition comprising:
- (a) from about 5% to 40% by weight of desmedipham;
- (b) from about 10% to 20% by weight of N-methylpyrrolidone;
- (c) from about 20% to 40% by weight of a hydrophobic aromatic solvent comprising aromatic hydrocarbons from about C9 to C16 and having a boiling range of from about 165° C. to about 290° C.;
- (d) from about 5% to 15% by weight of a surfactant which is a mixture of monohydrogen and dihydrogen phosphate esters of α-[2,4,6-tris[1-(phenyl)ethyl]phenyl ω-hydroxy poly(oxyethylene) wherein the poly(oxyethylene) portion averages about 16 moles per mole of the α-[2,4,6-tris[1-(phenyl)ethyl]phenyl ω-hydroxy portion;
- and
- (e) from about 2% to 15% of one or more surfactants, wherein said one or more surfactants is a polyoxyethylene C12-C15 alcohol having an average hydrophilic-lypophilic balance value of from about 5 to 15.
3 more elements
