Herbicidal compositions
View Patent ↗This invention relates to a new herbicidal composition comprising desmedipham and optionally phenmedipham and/or ethofumesate.
1. 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 having an average hydrophilic-lypophilic balance (HLB) value of from about 5 to 15.
2. The composition according to claim 1 , wherein the HLB value is from about 10 to 15.
3. The composition according to claim 1 , wherein the HLB value is from 12 to 14.
4. The composition according to claim 1 , wherein component (e) comprises one or more polyethoxylated alcohols.
5. The composition according to claim 1 , in the form of an emulsion concentrate.
6. The composition according to claim 1 , which is diluted with water to form a stable emulsion.
