| 摘要 |
This invention relates to inhibiting leaching of crop treating chemicals into the ground water, aqua-system and surrounding soil of the treatment site by contacting the plant or plant site with an effective leach inhibiting, plant tolerating amount of (a) a copolymer of a maleic acid or ester or a mixture thereof and a comonomer of an alkyl alpha alkenyl ether; or (b) a protein or carbohydrate derived polymer containing pendant hydroxy and secondary, tertiary or quaternized amino groups; or (c) a copolymer having pendant optionally quaternized amino or pyrrolidone groups; or (d) a lactam containing polymer selected from the group of an optionally crosslinked N-alkenyl lactam homopolymer or copolymer with a C2 to C30 comonomer selected from the group of an alkenoic acid, an alkenyl-anhydride, ester, ether, amino ester or amino amide and an alpha mono- or di-olefin; optionally including a water based wetting agent of a higher alkyl substituted lactam, anionic surfactant and water to enhance the wetting properties of herbicide and pesticide formulations.
