What is the most effective drug species for controlling different mechanisms of wheat scab? Can we sort and classify the drug types with different mechanisms, so that we can choose when we buy drugs. Suitable for the control of wheat scab disease drugs, mainly cyanoacrylate drugs cyanocastrobin, azole drugs tebuconazole, prochloraz, epoxiconazole, benzoimidazole drugs carbendazim, methyl Thiophanate, biogenic pesticide tetramycin, polyoxin B, methacrylates such as chlorfenone. At present, scab strains in many regions have produced high levels of resistance to carbendazim. In these regions, it is not appropriate to use carbendazim, thiophanate-methyl, or ketothiophene alone to control scab, and cyanogenic fungi should be used instead. Tebuconazole and other drugs and their mixed agents control. When multiple medications are used, different types of drugs are alternately or mixedly used to help ensure efficacy. From the perspective of production applications in recent years, a single dose of cyanocastrobin (Jinhuo) and its mixture with tebuconazole and hexaconazole, Jinxing 48% Cyanonbuxol Suspension, 20% solids Cyanoctazolol alcohol suspension, a mixture of tebuconazole and carbendazim, prochloraz, and thiamidone, such as carbendazim (Long Deng Fu Lian, etc.), tebuxaprozin, oxazolidine Drugs such as mycophenolate (Yanhuo) are effective drugs for preventing and controlling wheat scab, and adequate control of wheat scab has a good control effect. These drugs can be used preferentially in the production of wheat scab to prevent and control, and reasonable use usually has stable and good control effect. In addition, from the point of view of multiple pilot tests, prothioconazole, metconazole, fluconazol, and other drugs are also highly effective in the control of wheat scab, and the control effect is significantly better than conventional conventional drugs, and can effectively inhibit Fusarium head blight produces toxins. These drugs are expected to be registered for the control of scab in wheat in the next few years, and there will be more choices in the selection of agents for the control of scab.
