-
, (2008/06/13)
This invention relates to a water soluble matrix composition comprising an anionic surfactant, a C6 to C18 alkyl pyrrolidone, urea and a water insoluble copolymer of vinyl pyrrolidone with not more than 50 wt. % of a comonomer selected from the group of an α-olefin, vinyl acetate, an acrylic or methacrylic acid ester and methacrylamide as a free flowing particulate solid which matrix is suitably mixed with a water insoluble, chemically active component, such as an agrochemical, to provide a clear sprayable film forming emulsion, such as a non-leachable film on a plant or other substrate surface. The invention also relates to the method of preparing the matrix and to the incorporation of an agrochemical concentrate and plant spray composition.

, (2008/06/13)
The present invention relates to the stabilization of an agricultural chemical concentrate in aqueous solution and the stabilized concentrate which comprises: (a) between about 0.1 and about 20 wt. % of a stabilizer composition comprising: (1) between about 10 and about 90 wt. % of a water-insoluble, non-crosslinked, film forming polymer, and (2) a polymer solubilizing amount of an aromatic petroleum distillate or an oxygen-containing solvent of an N-alkyl pyrrolidone, a C3 to C8 alkanol, a dibasic acid lower alkyl ester, an ether having a boiling point above 150° C. or mixtures thereof and (b) between about 80 and about 99.9 wt. % concentrate containing a water-insoluble active agricultural chemical, a solvent for said agricultural chemical and a surfactant for said concentrate. The invention also relates to the use of said stabilized concentrate.
