实验证明，中生菌素２００倍液对水稻白叶枯病的防治效果达８９％，相当于化学农药１０％叶枯净１５０倍和２５％川化０１８５００倍药液处理。大田最佳施药时机为病株率５～１０％的发病初期，连续防治２～３次可有效控制病情，千粒重提高１７～１８．７％。秧田于３～４叶期和移栽前５天各喷中生菌素１５０倍液一次，可推迟大田发病期４５天，防效高达９０．５７％。同时节省防治成本７０～８０％。 Experiments show that 200 times of mycobater on bacterial leaf blight control effect of 89%, equivalent to 10 times the chemical pesticide leaf foliar net 150 times and 25% Chuhua 018500 times liquid treatment. The best spraying time in field is the early onset of disease strain rate of 5 ~ 10%, continuous control of 2 to 3 times can effectively control the disease, grain weight increased by 17 ~ 18.7%. Seedlings in the 3 to 4 leaf stage and 5 days before transplanting spraying of biocid 150 times a time, can delay the onset of field 45 days, control efficiency up to 90.57%. At the same time save the prevention and control costs 70 ~ 80%.
