With the arrival of autumn, the weather is getting colder, cabbage grows rapidly, and various pests occur one after another. In previous years, there were more occurrences of Bemisia tabaci and beet armyworms, so the agricultural technicians suggested that the majority of vegetable farmers should seize the critical period and take effective measures to prevent the insects from working in Chinese cabbage.
1. Artificial catching insects. Look at whether the heart leaves have insects, and secondly, see if there are "skylights" on the front of the leaves, and the third is to gently flip the leaves to see the leaves. The beet armyworm is crouching off the ground and should be carefully observed to gently turn the leaves to prevent the larvae from falling to the ground.
2. Conduct drug control. Bemisia tabaci can be uniformly sprayed with 1% methylaminobenzoate 2000 times solution or 10% imidacloprid 1500 times solution. Beet armyworm can choose 52.25% agricultural land 3000 times liquid or 2.5% cyhalothrin 2000 times liquid spray control. The two pest mixed plots can be mixed with the above agents, and 72% mancozeb 800 times solution can be added to prevent fungal diseases such as downy mildew.
3. Precautions. First, do not eat within 7 days after spraying the cabbage; second, do not increase the concentration of the drug at random; third, the amount of the drug should be sufficient, spray evenly; fourth, pay attention to the test 7-10 days after spraying, and re-use the drug as appropriate.
