Stabilized AGchemical concentrate and use thereof

A stabilized agricultural chemical concentrate of

• (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 polymer selected from the group consisting of a C.sub.1 to C.sub.12 alkyl vinyl ether/organic acid ester copolymer dissolved in (2) between about 90 and about 10 wt. % of a liquid selected from the group consisting of a petroleum distillate boiling between about 70.degree. C. and about 250.degree. C., an N--C.sub.8 to C.sub.16 alkylpyrrolidone, a C.sub.3 to C.sub.8 alkanol, a dibasic acid C.sub.1 to C.sub.4 alkyl ester, an ether having a boiling point above 150.degree. C. and mixtures thereof and
• (b) between about 80 and about 99.9 wt. % of an agrichemical concentrate containing an effective agriculturally active amount of a water insoluble active agrichemical dissolved in between about 10 and about 80 wt. % of an organic solvent and between about 1 and about 30 wt. % of a surfactant having a hydrophilic-lipophilic balance of from 3 to 20, said surfactant being selected from the group consisting of anionic surfactant and non-ionic surfactants and mixtures thereof.
