摘要
以德国鸢尾‘白与黄’品种为试材,研究了7种药剂处理对其软腐病的防治效果。结果表明:供试7种药剂都可以在不同程度上降低软腐病的发生。其中以农用硫酸链霉素5 400倍液喷雾处理的防治效果最好,至8月底发病率为23.34%,显著低于对照,相对防效显著高于其它处理,达到68.18%,其次是三氰酸和杀毒矾,发病率为33.34%,相对防效达到54.54%。
Taking Iris germanica L. ‘ white and yellow＇ as test material, the control efficacy of different fungicides on bacterial soft rot of Iris germanica L.‘white and yellow’ were investigated. The results showed that 7 treatments could reduce the occurrence of soft rot. Spraying agricultural streptomycin sulfate 5 400 times treatment had the highest control efficiency,to the end of August, the incidence rate of 23. 34%,significantly lower than the control,the relative control efficiency was significantly higher than the other treatments, to 68. 18%. Followed by three prussic acid and amivirus alum,an incidence rate of 33. 34% ,the relative the prevention rate reached 54. 54%.
