| Abstract: | Field trails were carried by using 0.3% azadirachtin emulsion at 15, 9and 5.625 g a.i./ha against waxberry drosophila of Biqi and Dongkui in orchard. The results showed that the control efficacy was 63.26 to 86.62% and active duration was 9 to 10 days at 9 g a.i./ha on Biqi. However, control efficacy was 74.5 to 88.36% and active duration was 8 to 9 days at 15 g a.i./ha on Dongkui. |
