First, early prevention of soil-borne diseases Vegetable soil diseases mainly include root rot, blight, verticillium wilt and so on. In order to minimize the risk of soil-borne diseases, the following measures are often used: The first is the use of pharmaceutical discs. Prior to colonization, soak the plug with 1000x solution of metalaxyl manganese zinc and allow to stand for 1-2 hours before colonization. The second is to apply 3-5g of high-quality microbial inoculum to each hole before planting vegetables, and must be fully mixed with the soil. The third is to irrigate or drench the stem with 54.4% hypha and WP 600 times before planting. Second, during the growing period of control During the growth of vegetables, due to bad external environmental conditions and technical measures are not in place and other reasons, causing vegetable leggy phenomenon. In order to effectively control plant leggy, use the following measures: First, strictly control the amount of water. The second is to reduce the use of available nitrogen fertilizers. The third is to spray plant growth regulators such as auxin, chlormequat, and paclobutrazol to control the growth of vegetables. Third, pest control to the road Due to the large ventilation and long ventilation time, the number of migratory insects in the shed is often increased. Measures for the prevention and control of migratory pests: The first is to install pest control nets at the ventilation openings. The second is hanging yellow sticky board inside the shed. The third is adding ovicides in the liquid. Fourth, disease prevention does not relax High temperature, high humidity or low temperature, high humidity, continuous cloudy and rainy days, poor ventilation and light transmission can all cause serious diseases. Common diseases include downy mildew and bacterial angular spot. In the early stage of the disease, the use of protective fungicides to control the effect is better, such as spraying 75% chlorothalonil 600 to 800 times and 50% carbendazim 500 to 600 times. When severe, use a therapeutic bactericide to control. For example, downy mildew can be sprayed with 500 mg of ethyl phosphorus phosphorus manganese zinc wettable powder, 800 times silver drip, and 600 to 700 times liquid chlorine. Bacterial keratoses were sprayed with 30% oxychloride copper chloride suspension 700 times, 77% WP 500 times, and 14% urea copper flux 300 times. Interval 7-10 days, even spraying 2-3 times can play a good effect. Note that the above agents must be used interchangeably to avoid plant resistance.
