摘要
选择8种不同的杀菌剂,用菌落生长速度法对桉树枝枯病主要病原菌可可毛色二孢、拟隐孢壳菌进行了室内毒力测定。结果表明:对可可毛色二孢抑菌效果最好的是25%咪鲜胺,EC50值为0.03 mg/L,效果最差的是50%异菌脲,EC50值为11.49 mg/L;对拟隐孢壳菌抑菌效果最好的是25%咪鲜胺,EC50值0.23 mg/L,效果最差的是25%苯醚甲环唑,EC50值为6.65 mg/L。
The toxicities of 8 selected fungicides to pathogens Lasiodiplodia theobromae(Pat) GriffonMaubl and Cryptospotiopsis sp.Bub.et Kabat causing die back of Eucalyptus spp.were tested in laboratory through growth rate method.The result showed that Prochloraz 25% EC was the most effective with EC50 value of 0.03 mg/L on Lasiodiplodi sp.,Ipordlone 50% WP was the least effective with EC50 value of 11.49 mg/L.Prochloraz 25% EC was the most effective with EC50 value of 0.23 mg/L on Cryptospotiopsis sp.,Difenoconazole 25%EC was the least effective with EC50 value of 6.65 mg/L.
