Abstract
A liquid herbicidal composition is provided, comprising: a. 20 to 35 percent by weight, based on the total weight of the composition, of a water-soluble herbicidal ingredient; b. a C12-C16 alkyl ether sulfate; c. an organic solvent; and d. an alkyl polyglucoside The composition is stable; i.e., it occurs in a substantially continuous, single phase at temperatures as low as −20° C. It also has a viscosity of no more than 2000 cps at temperatures as low as 0° C.
Claims19
A single phase liquid herbicidal composition comprising:
- a. 20 to 35 percent by weight of glufosinate or a salt thereof, based on the total weight of the composition;
- b. a lauryl ether sulfate or a salt thereof;
- c. an organic solvent;
- and
- d. a surfactant,
- wherein the organic solvent is an individual solvent or a solvent mixture, which is miscible with water in order to maintain the single phase of the composition,
- wherein the composition has a viscosity of no more than 2000 cps at temperatures as low as 0° C., and wherein the weight ratio of said glufosinate or a salt thereof (a) to the lauryl ether sulfate (b) ranges from 1:0.2 to 1:5.0.
