Herbicide Chemistry
The solubility of sulfonylurea herbicides (Envoke, Sandea) increases with higher pH
The amount of dissociation depends on the pH of the water
Dissociated herbicide molecules have a negative charge
Herbicides with high Koc values are sensitive to turbid water
Koc is the organic carbon sorption coefficient
