Abstract
A microemulsion composition is provided for use as an adjuvant with agrochemicals, comprising an oil phase component, a hydrophilic emulsifier, a lipophilic co-emulsifier and water.
Claims12
A method for treating plants with an agrochemical, comprising spraying the plants with the agrochemical in combination with a micro-emulsion composition consisting of:
- (a) from about 5% to about 50% of an oil phase,
- (b) from about 2% to about 20% of a hydrophilic emulsifier selected from the group consisting of alkyl(oligo)glycosides,
- (c) from about 2% to about 15% of a lipophilic co-emulsifier selected from the group consisting of glycerol esters of C6-C22 fatty acids, and sorbitan esters of C6-C22 fatty acids, and
- (d) from about 10% to about 90% water,
- wherein the ratio by weight of hydrophilic emulsifier to the combined weight of hydrophilic emulsifier and lipophilic co-emulsifier is from about 0.60 to about 0.80, and wherein said agrochemical is a water-soluble or substantially water-soluble agrochemical,
- whereby said micro-emulsion composition increases the field efficacy of said agrochemical over a similar method without said micro-emulsion composition.

- wherein the ratio by weight of hydrophilic emulsifier to the combined weight of hydrophilic emulsifier and lipophilic co-emulsifier is from about 0.60 to about 0.80, and wherein said agrochemical is a water-soluble or substantially water-soluble agrochemical,
- whereby said micro-emulsion composition increases the field efficacy of said agrochemical over a similar method without said micro-emulsion composition.
