Abstract | ||
Some adjuvants were mixed with the local mineral oil: CAPL-2 to increase its pesticidal efficiency: the adjuvants used were: xylene (Lypophilic agent), acetic acid and ascorbic acid (acidity modifiers) and acetone (polarizing agent). Adjuvants directly mixed with CAPL-2 at concentration of 0.8 % (V.N.). Pesticidal efficiency for CAPL-2 alone at concentrations of 1.5 % and 1.0 % and for its mixtures with adjuvants under rate I % were determined against sucking pests: whitelly and mites infested Cucurbita maxiuttta. Results obtained indicated that CAPL-2 at concentration of 1.5 % was suitable for controlling those pests, while concentration of 1 % was unsuitable. Mixing of adjuvants with CAPL-2 increased its initial and residual effect against pests and concentration of 1 % plus adjuvants became suitable for controlling pests. | ||
