According to Huang Jiahui, the station manager of the Plant Protection Station of the Municipal Central Agricultural Bureau, due to the lack of disease resistance in the promotion of high-quality rice, coupled with the promotion of local disaster-causing and no-tillage techniques in recent years, farmers have treated straw-treated straw. And the paddy field is not thoroughly ploughed, which makes the source of bacteria sufficient, leaving a safety hazard to rice production. She said that the key to preventing rice blast is to make a good "three barriers." That is to take the drug transplanting or immersion in the drug, picking up the leaf sputum, and preventing the neck stagnation. At present, we must effectively grasp the thorough treatment of open-air straw, and actively promote the application of drug dipping or transplanting with drugs to delay and prevent the occurrence of spider mites.
The specific method is: the medicine dipping, that is, before the seedling transplanting, using 20% ​​tricyclazole wettable powder 700~1000 times liquid or 75% Fengdeng wettable powder 1500 times liquid, dipping for 2~3 minutes, taking out the pile stuffy Transplanted in half an hour. If the medicine transplanting technique is adopted, it is 20 days before the transplanting, and 20% of the tricycloxazole wettable powder or 75% of the Fengdeng wettable powder is used for 45 kg of the conventional spray.
Agricultural experts reminded the majority of farmers that before the implementation of rice transplanting, they should do a good job in pesticide dipping and early prevention and control of rice blast.
