The early stage of wheat flowering is a critical stage for the initial infection of Fusarium oxysporum spores by Fusarium graminearum, as well as a critical period for prevention and control. Drugs that inhibit spore germination are mainly used, such as fluazuron, cyanomethoxam, pyraclostrobin, oxime ester, propiconazole ester, and their compound agents. 5-7 days later, wheat enters its peak flowering period, and successfully infected pathogens enter the stage of hyphal growth, which is also a critical period for toxin production. Drugs that inhibit hyphal growth, such as propiconazole, thalonil, tebuconazole, fluconazole, fluazithromycin, cyhalothrin, and their formulations, are mainly used; At the same time, toxin control should be considered, and some drugs that inhibit toxin production can be added, such as Jinggangmycin, Flupyram, and Fluconazole. Propiconazole and propiconazole · tebuconazole are effective in controlling wheat scab, with weak inhibition of spore germination and strong inhibition of hyphal growth. They are more suitable for use during the peak flowering period of wheat; Of course, it can also be used appropriately during the early flowering stage of wheat, but it is best to add some drugs that inhibit spore germination; Use up to two times per season, be sure to use the full amount of medication.
