Abstract
To screen new agents for effectively controlling(pepper Phytophthora blight),toxicity of9 fungicides was detected by mycelium growth rate method. The results showed that the pathogens were sensitive to dimethomorph,mandipropamid and fluopicolide( EC50 1 mg /L),followed by pyraclostrobin,metalaxyl,mancozeb and fluazinam(1 mg /L EC50 10 mg /L). Cotoxicity coefficient of dimethomorph + fluopicolide 2∶ 1,dimethomorph + fluopicolide 5∶ 1 and dimethomorph +fluopicolide 1∶ 5 were 850. 25,840. 15 and 837. 24,respectively.
