VISCOELASTIC SYSTEM FOR DRIFT REDUCTION

摘要

The invention relates to a viscoelastic system for drift reduction for pesticidal formulations, and the use thereof, wherein said formulation comprising at least one nitrogen-based cationic surfactant and at least one pesticide, wherein said pesticide contains at least one acid functional group associating with said cationic surfactant thereby forming a viscoelastic formulation.

主权项

1. A method of reducing spray drift of an aqueous pesticidal formulation comprising at least one pesticide which contains at least one acid functional group, said method comprising
adding to said formulation an effective amount of at least one drift control agent which comprises a nitrogen-based surfactant, wherein the acid functional group of said pesticide is capable of associating with said surfactant thereby forming a viscoelastic pesticidal system having reduced drift; spraying said formulation on a crop, wherein said sprayed formulation has a reduced spray drift.
