1. An adjuvant composition for use in aqueous herbicidal spray compositions comprising:
- (A) an amine alkaline compound in an amount to provide an alkaline pH of above about 7 to about 9 when formulated in a final spray composition;
(B) a neutral ammonium salt compound in an amount of from 5 to 30% by weight of the adjuvant;
(C) a non-ionic surfactant having a high Hydrophilic-Lipophilic Balance (HLB), in an amount of from about 15 to 80% by weight of the adjuvant; and
(D) sufficient water to make 100 percent of the adjuvant composition.

Abstract
Adjuvant compositions for herbicides comprising amine or ammonia compounds for adjusting the pH to the alkaline range, a neutral water soluble compound to provide a fertilizer action and a non-ionic surfactant and water. Herbicidal compositions using the adjuvant in combination with the herbicide are also included as well as methods for controlling weeds or undesirable vegetation by application of those compositions thereto.
