Q: On the cabbage stems, what bugs, blackheads, long white body, one centimeter long, translucent body, in the white gang, is not very clear, please take a closer look at the teachers! A: Hello, I took a closer look. The black beetle is a bit like the shape of a beak. This is a larva of the beetle. In the past few years, the yellow goose beetle has been serious in the Hebei radish producing area and slowly spread to large areas. Chinese cabbage is harmed. Therefore, the damage of Chinese cabbage in Hebei Province is also serious. This requires comprehensive prevention and control. If there is a variety of radish around the cabbage, it must be jointly controlled by the surrounding farmers. During the period from sowing to harvesting, we cannot relax. In the larval stage, acetamiprid plus bifenthrin or azadirachtin, thiamethoxam or dinotefuran is used for spraying. If there are wormholes in cabbage leaves later, thiamethoxam or acetamiprid is added. Qi Ling spray, spraying about 5 days again, pay attention to the field must be to help cabbage and other fields do not clean up the cabbage, to avoid adult spawning again.
