Control measures of rape locust

The locusts that harm rape are mainly radish and peach pods. Both of these two types of cockroaches are intensively planted on the back, stems, and flowers of rapeseed leaves with sorghum and rhizomes, sucking sap, destroying the leaves and chlorophyll, causing rolling leaves and dead seedlings. At the same time, aphids are an important medium for the transmission of rape virus disease, so the prevention and control of rape rape has a double effect. Main prevention measures:

First, use resistant varieties. Select rape varieties with strong resistance and comprehensive traits.

Second, timely sowing. The appropriate sowing date should be determined according to the local climatic conditions, species characteristics, and the occurrence of locusts. The rapeseed in Shizong County is generally sown in late September and early October.

Third, seed processing. Every 1 kilogram of rapeseed species is treated with 10% imidacloprid 20g plus adequate amount of water and sown to prevent and control seedling aphids.

Fourth, strengthen field management. Reapplying basal fertilizer and increasing phosphorus and potash fertilizers can make rape grow robustly, stems hard, and enhance rapeseed disease resistance and resilience. Clear weeds in the field, combined with seedlings and seedlings.

Fifth, pesticide control. Apply 10% imidacloprid 20g or 50% anti-inferiority WP 10-18g or enemy kill 20-30mL per acre to control the spray of water.
