摘要:
 在室内测定了10种化学杀菌剂对红叶石楠叶斑病病原菌小孢拟盘多毛孢（Pestalotiopsis microspora）的抑菌毒力。结果表明：7种化学药剂对菌丝生长有抑制作用，其中代森锰锌、嘧菌酯、咪鲜胺效果最佳，其抑菌率分别达66.77%、65.56%和71.11%，EC50值分别为4.867 7、4.628 3、4.499 7 μg·mL-1；选用代森锰锌、嘧菌酯、咪鲜胺进行野外防治试验，其防效分别达58.46%、62.88%和75.62%，其结果与室内基本一致。室内外试验结果表明代森锰锌、嘧菌酯、咪鲜胺可作为防治该病的药剂，其中咪鲜胺为首选药剂。
Abstract:
 The indoor toxicities of 10 antifungal agents to Pestalotiopsis microspora occurring in the leaves of Photinia fraseri were determined.The results showed that 7 fungicides could inhibit the growth of mycelium,among which mancozeb,azoxystrobin and prochloraz were able to achieve the best effects with inhibitory percentages of 66.77%,65.56%,and 71.11%,respectively;the corresponding EC50 values were 4.867 7,4.628 3,and 4.499 7 μg·mL-1,respectively.Through the field test with mancozeb,azoxystrobin,and prochloraz,the control effects reached 58.46%,62.88%,and 75.62% respectively,indicating that the field test results were basically identical with the indoor test.All results in field or indoor tests indicated that mancozeb,azoxystrobin and prochloraz could be used as the pesticides,and the prochloraz was the first selection to control the P.microspora leaf spot disease.
