多因子联合诱导辣椒对白粉病的抗病性研究

Research on the Resistance Induced with Multi-factors Combination of Pepper to Powdery Mildew

为了探索有效防治辣椒白粉病的新方法,将筛选得到的多个不同的抗病诱导因子进行配伍,组合成新的诱导组合体,研究其诱导辣椒苗对白粉病的抗病性影响。结果表明:诱导组合体的诱导效应比单一因子高;用不同的诱导组合体进行相继诱导和循环诱导,进一步提高了诱导效应,对辣椒白粉病的田间防治效果达到80%以上,高于常规杀菌剂的防治效果。

In order to study the new method to control powdery mildew of peppers effectively, the different in- ductive resistance factors were selected to combin into new inductive combinations,resistance of pepers to pow- dery mildew was determined. The results showed that the inductive effect of inductive combinations on powdery mildew of peppers was better than single factor. Both successive and repeated induction of different combina- tions further improved the inductive effect,the control rate of powdery mildew was over 80% in field,and the effect of combined induction was higher than conventional fungicide.
