Abstract
The studies were undertaken to establish optimum formulation recipes of acetamipid 4% SL(soluble concentrate) using different adjuvants and to evaluate enhanced control effect on target insect pests by adjuvants. Adjuvants for the studies used were SS(Sodium alkylcarboxylate) and PE(Polyoxyethylene alkyl ether). After the fundamental recipe for SL being established by using co-solvent for stability at low temperature, four types of SL were formulated. The physical properties and insecticidal efficacies of the tested SL formulations were investigated. Surface tension of SL1 without adjuvant was highly decreased from 44 dyne/cm to 34 dyne/cm by addition of adjuvants. SL4 using mixed adjuvant showed the lowest contact angle. Efficacies of SL1 without adjuvant against the palm thrips (Thrips palmi) and the cotton aphid (Aphis gossypii) on cucumber were increased by adding adjuvants. SL4 using mixed adjuvant showed higher efficacy than SL2 and SL3 using single adjuvant. These results have demonstrated that the selected adjuvants could be used to enhance insecticide efficacy and reduce spray dose of insecticide.
