Spring sowing is about to begin how to do a good job in the prevention and control of diseases, pests and pests.

Spring sowing is about to begin. In order to do a good job in the prevention of diseases, pests and rodents during spring sowing, the following prevention and control measures are put forward. I hope that all villages and towns will actively publicize and seriously implement them.

First, select disease-resistant varieties. Disease-resistant varieties are the basis of high yield and harvest. Suitable disease-resistant varieties can be selected according to the local microclimate, especially the combination of rice blast resistance.

Second, seed disinfection. Seed carrier is not only the primary infection source of many diseases, but also one of the main ways to spread diseases, especially rice blast, rice false smut, bacterial leaf spot and so on. Therefore, seed treatment before sowing is one of the important measures to prevent the occurrence of various diseases. The common methods are:

Third, disinfect the seedbed. Wet the flat seedling border with water before sowing, and then evenly spray 70% dioxon wettable powder or 75% chlorothalonil wettable powder or 3% Guangkuling water agent 800 times dilution on the border surface and sow seeds, which can reduce the occurrence of seedling cotton rot, blight, Phytophthora and seedling blast.

Fourth, do a good job in field treatment to reduce the source of diseases and insect pests. Combined with spring ploughing, weeds and straw in fields, ditches and ridges should be removed in time, and at the same time, the fields should be irrigated early to remove the sclerotia of sheath blight, so as to reduce the number of overwintering diseases and insect pests, such as Chilo suppressalis, rice gall midge, leafhopper and sheath blight in the field. reduce the occurrence of diseases and pests.

Fifth, pay attention to the prevention and control of rodent damage in seedling field. Rodenticide with high efficiency, safety and no secondary poisoning should be selected. The method is to use 0.1% diphacinone sodium salt poison bait or 0.0375% rodenticide bait or 0.005% bromadiolone to throw a pile of 5 grams every 5 meters along the ridge of the field.
