Oil dispersion with abamectin as active ingredient

Abstract

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.Aktivna materija abamektin ispoljava insekticidno i akaricidno dejstvo, a na nasem trzistu se pretezno nalazi formulisana u obliku koncentrata za emulziju (EC). Da bi se povecala efikasnost preparata najcesce se preporucuje njegova primena sa nekim adjuvantom, uglavnom uljem biljnog ili mineralnog porekla. Da bi se prevazisli problemi oko efikasnosti ove aktivne materije, pokusali smo da je formulisemo kao uljnu disperziju (OD) sa sojinim uljem kao disperznom sredinom. Sadrzaj aktivne materije u formulaciji iznosio je 1,8%. Razvijena formulacija je ispitivana pracenjem relevantnih parametara i na osnovu dobijenih rezultata zakljuceno je da ima potrebnu stabilnost. U narednoj fazi predstoji ispitivanje formulacije pri primeni, odnosno provera efikasnosti. PR Projekat Ministarstva nauke Republike Srbije, br. III 46008
