Indigo, tricyclazole and azoxystrobin can be used to control rice blast, among which tricyclazole has only protective effect, and rice bran and azoxystrobin have both preventive and therapeutic effects. For the control of rice blast, it is also possible to use prochloraz, rice amide, veramycin, trifloxystrobin, enestrobin and the like. In recent years, the rice blast pathogens in some areas may have higher resistance to rice blast, prochloraz and other drugs, resulting in decreased control effects. In these areas, it is better to use other drugs for prevention and treatment.
Both geranol and indigo have both preventive and therapeutic effects, and can be used to control rice blast. Heilongjiang Harbin Nongfeng Science and Technology Chemical Co., Ltd. 41% Chunlei • Dao Ling Ling WP, containing 1% of cerulein and 40% of glutinous rice, registered for rice control of rice blast, the recommended dosage per hectare of pure medicine is 307.5-615 grams, equivalent to 50-100 grams of preparation per acre, equivalent to 0.5-1 grams of pure drug per acre, 20-40 grams of rice glutinous rice. Each acre uses 4% spring saumycin 60g, 40% rice blast, 160g, the dosage is large, and the appropriate application has good control effect against rice blast.
Chlorobromoisocyanuric acid is a broad-spectrum fungicide that has a strong killing effect on bacteria, fungi and viruses that harm crops. Spraying on the surface of crops can release hypobromous acid and hypochlorous acid slowly, which has a strong bactericidal effect. . The drug has certain control effect on rice blast, but it is not used to control rice blast, especially it can not be used to control panicle neck mites, so as to avoid large loss of yield caused by poor control.
Prochloraz, tricyclazole and chunleimycin are suitable drugs for controlling rice blast. Among them, tricyclazole has only protective effect, and prochloraz and veramycin have both preventive and therapeutic effects. Prevention and control of rice panicles, mainly in the rice break period, the rice heading period encountered continuous low temperature and rainy weather, or rice resistance to rice blast is not strong, should be used again at the heading stage. In the initial stage of rice rupture, use 25% prochloraz 100g and 75% tricyclazole 20g per acre. 7-10 days after the heading, use 25% prochloraz 100g and 2% Chunremycin 200g per acre. Panicle neck mites have better control effects, and these drugs can still be used to control panicle neck lice. The second application time can be advanced to the heading period.
