PESTICIDE NANO-SUSPENSION

摘要

Many active agents, such as insecticides, herbicides and fungicides are relatively insoluble in aqueous media. In order to apply them efficiently to crops it is thus necessary to formulate them in a manner that facilitates their dilution in the water based spray media used in practice, by the farmer or contract spray operator. The present invention relates to aqueous dispersions of agents such as insecticides, herbicides and fungicides, in particular such dispersions in which the particles are of sub-micron diameter.

主权项

1. A composition comprising an aqueous dispersion of particles, wherein the particles comprise a surface active agent and one or more active agents selected from herbicides, insecticides or fungicides, the mean particle diameter is 500 nanometers or less, the surface active agents a polyetheralkanolamine comb polymer, and wherein the composition comprises at least 25% by weight of active agent.
