摘要：
A substantially dry, flowable adjuvant compositions comprising, based on 100parts by weight ("pbw") of the adjuvantcomposition: (a) from about 25 pbw to about 75 pbw of a polysaccharide and (b)from about 75 pbw to about 20 pbw of asalt composition. In one embodiment, the salt composition is diammoniumhydrogen phosphate, sodium carbonate or a combinationthereof, and the polysaccharide is a derivatized guar. Also disclosed aremethods of preparing such agricultural compositionscomprising adding, to a heel solution, (a) a water dispersible adjuvantcomposition, in an amount effective to provide depositionand/or drift control properties, comprising, based on 100 pbw of the adjuvantcomposition: (i) from about 25 pbw to about 75 pbwof a polysaccharide, and (ii) from about 75 pbw to about 20 pbw of a saltcomposition, wherein an aqueous solution of the adjuvantcomposition has a pH value of between about 7 and about 12, and (b) aneffective amount of an active. The adjuvant compositioncan further comprise (iii) from about 20 pbw to about 30 pbw of a dispersingagent, wherein typically the dispersing agent issodium polyacrylate.
