Abstract
In this paper,the control efficacy of 1. 5 % Matrine SL against aphids were studied in the fields. The results showed that 1,7,14days after treating,the control effect of 1. 5 % Matrine 4. 5,6. 75,9. 0 g a. i. / hm2against aphids in cucumber were 16. 4 %- 36. 6 %,82. 7 %- 94. 9 %,84. 4 %- 96. 1 %,in cowpea 21. 5 %- 39. 9 %,79. 8 %- 92. 8 %,81. 7 %- 95. 1 %,and in eggplant 3. 5 %- 31. 6 %,75. 6 %- 93. 0 %,79. 2 %- 94. 5 %,respectively. 1. 5 % Matrine SL had a good control effect on aphids in cucumber cowpea and eggplant.
