Application mode
(1) When the cabbage caterpillar was 2-3 years old, it was sprayed with 40.7% Oxfam EC 1 000- 1 500 times.
(2) At the peak of 1-2 instar, the diamondback moth was sprayed with 40.7% l 000- 1 200 times EC.
(3) Because the generations of Bemisia tabaci overlap in the greenhouse, all stages exist at the same time. According to the vertical distribution law of each stage, we should carry out targeted control at the corresponding stage to ensure the control effect. 800- 1 000 times of 40.7% lesburn EC can be sprayed, and the corresponding dose can also control the pea leafminer.
