A Review of Pesticide Formulations for Chemigation

TL;DRAbstract

Pesticides applied in irrigation water (chemigation) may require modified formulations for effective and safe application. Currently available insecticide formulations produce variable insect control when applied through chemigation systems. Pest control is greatly influenced by the chemical properties, e.g. solubility in water and organic solvent. When emulsified formulations or technical pesticide are added to a nonemulsified oil, significantly better control of foliar-feeding insects is obtained compared to emulsified formulations applied with conventional-ground applications. Chemigation of technical-oil formulations of insecticides may allow for reduced active ingredient for effective insect control. Currently available herbicide formulations produce varied weed control when applied through chemigation, depending on application to soil or foliage, the volume of irrigation water, and the chemical properties of the compound. Water-soluble herbicides applied postemergence produce the
