Comparative Study of Properties of Different Pesticide Formulations of the Same Active Ingredient

Abstract

Characteristics of two formulations of trifluralin, an emulsifiable concentrate (EC) and emulsion, oil in water (EW), the latter being a new formulation of our design, were investigated and compared. Attention was focused on particle size distribution and aspects of the two aqueous dilute formulations as the most characteristic and comparable parameters. The results show that the trifluralin EW formulation has certain advantages over the EC formulation, but a final estimate will be possible only after testing biological efficacy of the new formulation (EW).

U radu su ispitivane i upoređivane karakteristike dve formulacije trifluralina, koncentrat za emulziju (EC) i emulzija ulja u vodi (EW), koja je potpuno nova – nastala kao rezultat sopstvenog rada. Tokom ispitivanja pažnja je bila usmerena na poređenje granulometrijskog sastava i izgleda pomenutih formulacija u razblaženju, kao karakterističnih parametara za poređenje. Rezultati ispitivanja su pokazali da formulacija trifluralina ulje u vodi (EW) pokazuje izvesne prednosti u odnosu na koncentrat za emulziju (EC), s tim da će se konačna ocena dobiti nakon ispitivanja biološke efikasnosti nove formulacije (EW).
