Because of the low temperature and high humidity in the winter shed, it is difficult to prevent diseases after the occurrence of diseases. Therefore, many vegetable farmers increase the use concentration of pesticides to enhance the disease prevention effect. Farmers believe that the greater the concentration of drugs, the better the treatment effect, especially in the high incidence of disease, but also multiplied the drug concentration. Practice has shown that increasing drug concentration can improve the disease prevention effect, but its side effects can not be ignored. If it can make the resistance of pathogenic bacteria produce faster, it will increase the difficulty of controlling the disease later; it is also prone to phytotoxicity, which affects the normal growth of the crop. Therefore, it is not advisable for vegetable farmers to conduct pest control only by increasing the amount of pharmaceuticals used. To control pests and diseases, multiple methods should be used in combination with comprehensive prevention and treatment. The first is to enhance the plant's own resistance. With the growing number of fruit and vegetables in plants, the organic and inorganic nutrients in the plants are lacking, and the disease resistance is reduced. When the weather is overcast and rainy, the temperature and the ground temperature in the greenhouse decrease, the growth of the root system is blocked, the plant growth weakens, and the disease resistance decreases. Disease infestation. Therefore, we must pay attention to nurturing strong trees, can not leave too much fruit, leading to plant nutrient supply shortage and premature aging defertilization. The second is to create a good shed environment. Any disease has its own suitable disease environment. Only when the environment is suitable, the disease may be outbreak. For example, gray mold disease is heavy in the low temperature and high humidity season, so it often appears as an outbreak after the sunny days in winter. Therefore, the prevention and control of diseases must first be regulated in the environment of the greenhouse. The vegetable farmers can take various measures to prevent the air humidity in the greenhouse from exceeding 80% for a long time and reduce the chance of disease and infection. At the same time, the old leaves and diseased leaves in the shed were promptly removed to reduce pathogens and prevent the infection of diseases. Again is alternating medication. The more times a pesticide is used, especially when it is used continuously, the greater the chance of the bacteria producing resistance. Many kinds of pesticides, although they work well when they are used, are not used several times in a row, and their effects are greatly reduced, such as metalaxyl. Therefore, vegetable farmers should do alternate use of drugs to prevent bacteria from rapidly developing drug resistance. Such as the prevention and treatment of cucumber downy mildew, you can use bramidine hydrochloride and metalaxyl manganese zinc, dimethomorphs and other alternate use.
