Abstract
The invention relates to stable liquid compositions comprising cyclohexanedione oxime herbicides (preferably clethodim), a water miscible solvent (preferably alkyl benzene), and at least one non-ionic surfactant (preferably mixture of lower HLB surfactant with higher HLB surfactant, or alternatively mixture of high HLB surfactants and fluroxypyr meptyl) and uses thereof.
Claims35
A stable, liquid composition comprising (a) an amount of a cyclohexanedione oxime compound;
- (b) a low water miscible organic solvent;
- (c) at least one non-ionic surfactant and/or at least two non-ionic surfactants, and/or (d) the composition is substantially free of ionic surfactant, and/or (e) the cyclohexanedione oxime compound is present in an effective amount.

A method for:
- (a) increasing the shelf-life, the stability, the herbicidal efficacy or any combination thereof of a composition comprising cyclohexanedione oxime compound, comprising formulating the composition to be substantially free of ionic surfactant and using at least one or at least two non-ionic surfactants for physical stabilization of the composition, or:
- (b) increasing the chemical stability of cyclohexanedione oxime compound comprising reducing the amount of anionic surfactant to equal to or less than 0.2% by weight based on the total weight of the composition, or:
- (c) increasing the chemical stability of cyclohexanedione oxime compound, comprising reducing the amount of anionic surfactant to equal to or less than 0.2% by weight based on the total weight of the composition, or:
- (d) stabilizing a liquid composition comprising a cyclohexanedione oxime compound and low water miscible organic solvent, comprising formulating the composition in absence of ionic surfactant and in presence of at least one non-ionic surfactant, or:
- (e) physically stabilizing a liquid composition of cyclohexanedione oxime compound in low water miscible organic solvent in absence of ionic surfactant after dilution, comprising formulating the composition to have a high HLB by using at least one polymeric surfactant having a high HLB value, or:
- (f) improving the physical stability of a liquid composition comprising a cyclohexanedione oxime compound in a low water miscible organic solvent in the absence of ionic surfactant after dilution wherein the composition comprises a high HLB component and/or surfactant, comprising formulating the composition with at least two polymeric surfactants.
