【 摘 要 】

 To determine the impact of citowett oil and commercial neem extract mixture against the Pieris brassica these experiments were under taken. Citowett as a wetting agent was used in conjunction with neem extract against the larval stage of the pest in question. The LC50 values of neem extract and combination with citowett oil for second and third instars larvae were estimated, 4.40, 3.89 and 3.38, 2.16 ppm, respectively. The combination of neem extract with citowett increased the larval mortality rate up to 15%. This implies that the application of the mixture is a sound measure for enhancing lethality impacts.Based on collected data it could be concluded that combination of these two less hazardous chemicals is merit to be considered as a candidate control agent against Pieris brassica
