pyrifenox是一个具有保护和治疗作用的新杀菌剂。该药剂可防治子囊菌纲、担子菌纲和半知菌纲的多种植物病原菌。pyrifenox以5克(有效成分)/百升施用时,能有效地防治苹果黑星病和白粉病。用量为37.5～50克(有效成分)/公顷时,可防治葡萄白粉病。防治花生上的落花生早期叶斑病和晚期叶斑病,用量需要70～140克/公顷(有效成分)。作物对该药剂的耐药力极好。根据其生物特性和在环境中的行为看,pyrifenox是目前用于病害综合防治的最适合药剂。该药剂1986年在瑞士首次应用,本文将报道该杀菌剂的特性。
Pyrifenox is a new fungicide with a protective and therapeutic effect. The medicament can prevent and treat various plant pathogenic bacteria of Ascomycetes, Basidiomycetes and Semilattices. When pyrifenox is applied at 5g (active ingredient) per 100L, it can effectively control apple scab and powdery mildew. The amount of 37.5 to 50 grams (active ingredient) / ha, can control grape powdery mildew. Control peanut early leaf spot on groundnut and late leaf spot disease, the amount required 70 ~ 140 g / ha (active ingredients). The resistance of crops to the agent is excellent. According to its biological characteristics and behavior in the environment, pyrifenox is currently the most suitable agent for integrated disease prevention. The agent was first applied in Switzerland in 1986 and this article reports on the characteristics of the fungicide.
