Soluble polymer based matrix for chemically active water insoluble components
-
, (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.

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.

The 1-(3,5-bis-trifluoromethylphenyl)-2-thioxopyrrolidine-4-carboxylic acid derivatives of the formula I below are suitable for protecting crop plants against the phytotoxic action of herbicides and for regulating the plant growth. The 1-(3,5-bis-trifluoromethylphenyl)-2-thioxopyrrolidine-4-carboxylic acid derivatives are those of the formula I STR1 wherein A is --COOR1, --COSR1, --COO? M≈, --CONR2 R3 or --COCl; R1 is hydrogen, C1 -C4 alkyl, C2 -C6 alkenyl or C2 -C6 alkynyl; R2 and R3 independently of one another are hydrogen, C1 -C4 alkyl or C3 -C7 cycloalkyl; or R2 and R3 together with the nitrogen atom to which they are bonded are a saturated 3- to 7-membered heterocycle which can contain an additional hetero atom selected from the group comprising O, N and S and which is unsubstituted or up to trisubstituted by C1 14 C4 alkyl; and M≈ is the equivalent of an alkali metal cation or an alkaline earth metal cation or HN≈ (R2)3, and their isomers in optically pure or enriched form.
