Claims17
A pesticide formulation comprising a pesticide, an adjuvant and a monoalkyl sulfosuccinate hydrotrope having the structure:
- where
- R is a linear or branched alkyl group comprising 3-4 carbons;
- X is O;
- Y and Z, independently of one another, comprise H or —SO3M′ where M′=sodium, ammonium, potassium, or calcium, wherein at least one of Y and Z comprises —SO3M′;
- and
- M is a sodium, ammonium, potassium, calcium, ethylamine, propylamine, isopropylamine, or alkanolamine;
- wherein a weight ratio of pesticide to adjuvant is about 1:1 to about 1:5.
