A composition contains an incompletely hydrated water soluble polymer suspended in a liquid medium.

Polymer compositions

A substantially dry, flowable adjuvant compositions comprising, based on 100 parts by weight ('pbw') of the adjuvant composition: (a) from about 25 pbw to about 75 pbw of a polysaccharide and (b) from about 75 pbw to about 20 pbw of a salt composition. In one embodiment, the salt composition is diammonium hydrogen phosphate, sodium carbonate or a combination thereof, and the polysaccharide is a derivatized guar. Also disclosed are methods of preparing such agricultural compositions comprising adding, to a heel solution, (a) a water dispersible adjuvant composition, in an amount effective to provide deposition and/or drift control properties, comprising, based on 100 pbw of the adjuvant composition: (i) from about 25 pbw to about 75 pbw of a polysaccharide, and (ii) from about 75 pbw to about 20 pbw of a salt composition, wherein an aqueous solution of the adjuvant composition has a pH value of between about 7 and about 12, and (b) an effective amount of an active. The adjuvant composition can further comprise (iii) from about 20 pbw to about 30 pbw of a dispersing agent, wherein typically the dispersing agent is sodium polyacrylate.

Low use rate agricultural compositions and methods for use

Agrochemical oil dispersions are stabilized to particle sedimentation by use of a combination of a clay or silica type rheology modifier and a polymer or oligomer capable of hydrogen bonding.
