摘要
在室内培养条件下,采用生长速率法测定了10种常用杀菌剂对桉树小新壳梭孢枝枯病菌Neofusicoccum parvum (Penny Cook & Samuels)的抑制效果,结果表明:25％苯醚甲环唑和25％丙环唑对N.parvum抑制效果最好,EC50值分别是0.0312和0.0330 mg/L;18.7％丙环·嘧菌酯、25％咪鲜胺、50％甲基硫菌灵、50％异菌脲、50％多菌灵、40％腈菌唑和75％百菌清抑菌效果次之,EC50值分别为0.0499,0.0681,0.1462,0.1672,0.2720,0.3454和4.6199 mg/L;25％嘧菌酯抑菌效果最差,EC50值是16.1451 mg/L.
Abstract
The inhibition effects of 10 commonly used fungicides on Neofusicoccum parvum were tested with growth rate methods indoors.The results indicated that difenoconazole 25％ EC and propiconazole 25％ EC were most effective,the EC50 values of which were 0.0312 and 0.0330 mg/L respectively.The inhibition effects of propiconazole-azoxystrobin 18.7％ SC,prochloraz 25％ EC,thiophanate-methyl 50％ SC,iprodione 50％ SC,carbendazim 50％ WP,myclobutanil 40％WP and chlorothalonil 75％ WP followed,the EC50 values of which were 0.0499,0.0681,0.1462,0.1672,0.2720,0.3454,4.6199 mg/L,respectively.Azoxystrobin 25 ％ SC presented the worst inhibition effect,the EC50 values was merely 16.1451mg/L.
