Oil Dispersion with Abamectin as Active Ingredient

Abstract

Abamectin was developed as an insecticide, nematocide and acaricide for use on a varietyof agricultural and horticultural crops. The products with this active ingredient can befound on the market mostly formulated as emulsifiable concentrate (EC). Usually producersrecommend using the EC formulation of abamectin together with some kind of adjuvants(natural oils) to improve efficacy of the active ingredient. To overcome the efficacy problemwe tried to formulate the active ingredient abamectin as oil dispersion (OD). Oil dispersion,preferably based on naturally derived oils could improve pesticide efficacy. This type of pesticideformulation contains oil instead of water as in classical suspension concentrate andtypically has better retention and coverage. In the case of abamectin, in this investigationsoybean oil was used with the mixture of different nonionic emulsifiers. Content of abamecetinin formulation was 1.8 %. The developed formulation was tested for few importantparameters. The obtained physicochemical properties for the above mentioned formulationhave shown that it is stable and could be used in plant protection.
