Abstract
Half salts of certain synthetic auxin herbicides are provided. These half salts are useful for controlling unwanted plant growth. The half salts have low solubility in water, low volatility relative to commercial compositions of the corresponding synthetic auxin herbicides, and offer comparable herbicidal performance when compared to existing salts of the synthetic auxin herbicides.
Claims43
A half salt of a synthetic auxin herbicide that has the formula
- wherein R is independently H or CH3;
- n is an integer selected from 1, 2 or 3;
- Ar is a phenyl or pyridine group substituted with one or more substituents selected from halogen, C1-C6 alkyl, C1-C6 haloalkyl, C1-C6 alkoxy, amino, C1-C6 alkylamino, and di(C1-C6 alkyl)amino;
- and M is a monovalent metal cation or a tetrasubstituted ammonium ion;
- and
- wherein the half salt has a water solubility within a pH range of from about 3 to about 6 of less than about 1 wt % with respect to the total weight of water and the half salt.
