Chinese Cabbage Pest Control Technology
First, there are three major diseases of Chinese cabbage, namely: soft rot, virus disease, downy mildew, its spread and pests are inextricably linked, to prevent the three major diseases must first pest control. Second, soft rot disease caused by bacteria invade. The control of cabbage caterpillars, flea beetles and underground pests, and the reduction of pest wounds can effectively reduce the incidence of soft rot of Chinese cabbage. 80% of dichlorvos EC and 80 times of 13T can be applied to cabbage caterpillars and flea beetle. 50% phoxim EC 1000 times, rooting poison. 3. Viral diseases are caused by virus infection. Aphids are the main vectors for transmitting viruses. To prevent virus diseases, it is necessary to prevent locusts from harming first. The seedling stage is the period during which locusts move into danger. It is easy to spread virus diseases. It must be prevented and treated as soon as possible after emergence. , with 40% Dimethoate EC, vinegar and water, in accordance with the ratio of 1:2:2000 sprayed with liquid, but also can choose to use a big hero, once again net plus vinegar diluted with water to spray, pesticide solution plus vinegar, Not only can increase the effect of killing locusts, but also prevent and suppress the occurrence of viral diseases. 4. Downy mildew is a fungal disease. Although its occurrence is not directly related to pests, the early stage of Chinese cabbage infection often causes severe downy mildew in the middle and late stages. Viral disease is mainly transmitted by roundworms to kill aphids. It also indirectly protects Chinese cabbage from downy mildew. 10000Hz High Frequency LiDAR Module 10000 Hz is one of our 2021 new solutions products,which can be widely used in drone postioning, car anti-collision, intelligent traffic monitoring etc. with high accuracy.
