Abstract

The invention discloses a fungicidal composition containing triconazole and difenoconazole, wherein the weight ratio of triconazole to difenoconazole is (1-80): (70-1), preferably (1-60): (50-1), most preferably (1-10): (2-1). The bactericidal composition of the present invention broadens the application range of the medicament, prolongs the effective period, improves the drug effect, reduces the dosage of the mixed agent, greatly improves the drug effect, reduces the production cost, and has obvious synergistic effect after compounding. Delaying the drug resistance of pathogens, reducing drug damage, less damage and pollution to the ecological environment, is conducive to protecting the safety of humans and animals, and can be used to prevent and control sugar beet brown spot, wheat rust, and wheat powdery mildew.

Description

technical field [0001] The invention relates to a bactericidal composition containing active ingredients triconazole and difenoconazole, and belongs to the technical field of pesticide compounding. Background technique [0002] Cereal powdery mildew is a relatively common disease on crops, often causing devastating disasters, especially in southern regions, where it occurs throughout the year and is difficult to control. In some serious areas, conventional pesticide ingredients are difficult to control when used alone, and the effect is very poor. [0003] Fenconazole has broad-spectrum bactericidal activity, inhibits the synthesis of ergosterol, and can cause the rupture of fungal cell walls and the growth of hyphae. Triconazole is also a fungicide with eradication, protection, contact and systemic activities. It has good protective and therapeutic effects on many diseases caused by basidiomycetes and ascomycetes, and has a certain fumigation effect. Inactive. The drug h...
