摘要
采用菌丝生长速率法进行了5种药剂对辣椒枯萎病菌的毒力测定。结果表明,所采用的5种药剂均对辣椒枯萎病菌有抑制作用。药剂EC50大小顺序依次为甲霜·噁霉灵>噁霉灵>百菌清>科佳>腐霉利,其中甲霜·噁霉灵最高为19.4mg·L-1,腐霉利最低为5.4mg·L-1。
The toxicity to 5 fungicides to pepper Fusarium oxysporum was determined by mycelia growth inhibition method. The result showed that 5 fungicides all inhibited mycelia growth of pepper Fusarium oxysporum. The ECs0 order of 5 fungicides was hymexazolmetalaxyl 〉 hymexazol 〉 chlorothalonil 〉 1H-Imidazole-l-sulfonamide 〉 procymidone. Among the five ECso, the highest ECso( 19.4 mg·L^-1) was observed from hymexazolmetalaxyl, the lowest EC5o(5.4 mg·L^-1) was observed from procymidone.
