To control soybean pests and diseases, the problem of phytotoxicity is the most problematic problem for farmers. If you want to solve the problem of phytotoxicity completely, the best way is to use no pesticides . Let's take a look at it with Xiaobian.
(1) Seed selection: According to local climatic conditions, soil and cultivation techniques, select soybean varieties that are resistant to pests and diseases, strong in stress resistance, and good in commodity. The seed quality meets the requirements of Grade 2 and above in GB8079. Refuse to use genetically modified soybean seeds.
(2) Seed treatment:
1 Drying treatment: Dry the selected seeds for 1 to 2 days, and strictly prohibit exposure.
2 high temperature hot seeding: in order to kill the eggs and germs attached to the seed coat before sowing, high-humidity hot-spotting can be used. The selected seeds are placed in the pot, and the seeds are quickly burned with hot water of about 90 °C. Then add cold water to cool down, keep the water temperature 25 ~ 30 ° C, and soak for 4 to 6 hours, the seeds are removed and slightly sown. Because the beans are sensitive to changes in temperature and humidity, in order to avoid larval root injury, it is generally not germinated before sowing.
(3) Disinfection and management of seedbed: The disinfection of seedbed soil, the protection of roots, nursery and nutrition, the disinfection of greenhouses, the prevention and control of seedlings, etc. are all referenced to the beans.
The above is the zero pesticide technology for soybean pest control. To learn more about pesticides, please pay attention to China Pesticide Network.
