Abamectin was developed as an insecticide, nematocide and acaricide for use on a variety of agricultural and horticultural crops. The products with this active ingredient can be found on the market mostly formulated as emulsifiable concentrate (EC). Usually producers recommend 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 problem we 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 pesticide formulation contains oil instead of water as in classical suspension concentrate and typically has better retention and coverage. In the case of abamectin, in this investigation soybean oil was used with the mixture of different nonionic emulsifiers. Content of abamecetin in formulation was 1.8 %. The developed formulation was tested for few important parameters. The obtained physicochemical properties for the above mentioned formulation have shown that it is stable and could be used in plant protection.
