NOVELTY - Preventing and treating rice bakanae disease, involves carrying out ecological management, applying fertilizer, choosing terrain, irrigating, cropping rice seedling, carrying out agricultural control, selecting plant disease resistant varieties, using nitrogen, potassium fertilizer and water, carrying out biological control, physical control and chemical control using pharmaceutical cream or Mancozeb (RTM: Fungicide), fertilizer and propineb, spraying formalin and soaking in seedvax thiram or carbendazim and water to dissolve or mix rice with thiophanate-methyl wettable powder.    USE - The method is useful for prevention and treatment of rice bakanae disease (claimed).    ADVANTAGE - The method comprehensively prevents and cures rice bakanae disease, increases yield and grade of rice and ensures excellent economical benefit.    DETAILED DESCRIPTION - Preventing and treating rice bakanae disease, involves carrying out ecological management, applying microbial fertilizer, improving soil physical and chemical properties, soil fertility, enhancing absorption capacity, choosing terrain for seedling, irrigating, draining, threshing, continuously cropping the rice seedling in rice field free from disease, carrying out agricultural control, selecting plant disease resistant varieties, establishing disease free farm stay, unplugging overnight seedlings, aging seedlings, deep mud seedlings, sun vine seedling, and cold water seedling, timely removing diseased plants, burning sick straw as fuel, composting pile material, transplanting seedlings with soil, rotating the crop, pulling up seedlings, transplanting to avoid root damage, using suitable nitrogen, potassium fertilizer and water, carrying out biological control of leafhopper, whitefly, aphid, and thrips pest population, and reducing pathogens, and dry-spraying 0.3% polymyxin agent for 300 times, carrying out physical control, properly handling diseased straw, germs and bud, carrying out chemical control using 58% pharmaceutical cream wettable powder for 500 times or 80% Mancozeb (RTM: Fungicide) wettable powder 500 times, fertilizer and 70% propineb wettable powder 500 times, spraying 2% formalin for 3 hours at a temperature above 20 degrees C using seed soaking method, and soaking in 40% seedvax thiram wettable powder or 50% carbendazim wettable powder, and small amount of water, dissolving and mixing rice with 50% thiophanate-methyl wettable powder.
