1. An aqueous herbicidal spray composition consisting of:
an adjuvant blend consisting of a cationic surfactant and a basic pH adjustor in an amount effective for providing an alkaline pH of above 9 to about 10.5 when formulated in the aqueous spray composition; and an effective amount of a sulfonylurea or sulfonamide herbicide.
