- 摘要:
- 以库尔勒香梨腐烂病菌田间发病枝条为试材，采用生长速率法和刮除病斑后涂抹药剂的方法，研究了5种不同杀菌剂对库尔勒香梨腐烂病菌的影响。结果表明：室内毒力测定中阿米妙收、银典和世高的防效较好，其EC50值分别为0.0193、0.0312、0.0563 μg/mL；凯润和好力克防效次之；田间防治时阿米妙收50倍、凯润50倍防效最好，病斑愈合宽度和治愈率分别为17.1 mm、93.6%和16.8 mm、90.0%；好力克20倍防治效果次之，病斑愈合宽度和治愈率分别为9.3 mm、82.4%；银典防效相对较差。
- Abstract:
- Taking the field disease shoots of Korla fragrant pear canker as materials,using growth rate method and curettage of lesion after smearing agent method,the effect of 5 fungicides on Korla pear rot pathogen were studied.The results showed that control effect of Ami Miao-shou,Yin Dian and Shi Gao were better,the EC50values were 0.0193,0.0312 and 0.0563 μg/mL;control effect of Kai Run and Hao Li-ke were worse than three of them.50 times Ami Miao-shou and 50 times Kai Run were the best control effect,their width of lesion healing and cure rate were 17.1 mm,16.8 mm and 93.6%,90.0%;the width and the cure rate of 20 times Hao Li-ke were 9.3 mm and 82.4%;the control effect of Yin Dian was worse.
