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.
