摘要
选用10种药剂对瓜类果斑病菌进行室内毒力测定。结果表明:各种药剂对瓜类果斑病菌均有一定的抑制效果,但不同药剂之间差异较大。其中,以88%水合霉素的抑制效果最好,有效中浓度(EC50)为89.40mg/L,其次是33.5%喹啉酮和72%农用链霉素,因此这3种药剂可作为防治瓜类果斑病的首选药剂;而其他药剂的抑制效果较差,不适于病害防治。
In this assay 10 bactericides were tested for lab toxicity measurement of Acidovorax avenae subsp.Citrulli.The results showed that the inhibitory effect was greatly significant difference between the 10 bactericides.Among them Hydrated neomycin had the best high activity,the effective concentration 50(EC50)was 89.40mg/L,the next best were Quinoline ketone and Agricultural streptomycin.Therefore the three bactericides were selected firstly on controlling bacterial fruit blotch disease,the others were unsuitable.
