Basis Blend herbicide replaces DuPont Basis 75DF herbicide this year. Basis Blend is offered in an improved dry-blended formulation, which dissolves more completely than Basis 75DF for more effective burndown and residual control of glyphosate-tolerant and glyphosate-resistant weeds, plus other key weeds, including dandelion, poison hemlock, annual bluegrass, henbit and other winter annuals. It can be applied any time after harvest, but before ground freeze.
