In order to prevent cotton bollworm and Helicoverpa armigera, the
2.5% generation of second, third times of egg spray was used to
spray the red spider, the bridging worm and the cotton bollworm.
The control of cabbage caterpillar and aphid were sprayed at the
concentration of 6 ~ 10mg/L and 6.25 ~ 12.5mg/L respectively, and
the spraying of 4.2 ~ 6.2mg/L concentration was carried out to
control the leaf miner of citrus.
