LI Yu-jing12， PANG Min2 ，DU Xiao-tian2 et al（1.

Plate inhibition test showed that the EC50 values of 43% Lunason （ 21.5% fluopyramide +21 5% 0xime ester），Cuibei （ 50% ether ester）， 80% Ethylicin（allicin homolog），Chlorothalonil（ 75% tetrachloro-isophenonitrile）was 0.000 177 0 ， 0.005 534 0，0.006 3460，0.031 7856 μg/mL，respectively. 43% Lunason had an obviously significant antibacterial effect，followed by Cuibei and 80% Ethylicin. The results of fruit control test showed that the relative control effects of 43% Lunason and 80% Ethylicin was 88.89% and 85.17% ，respectively.[ Conclusion]The results ofthis studyshowed that the four fungicides have inhibitory efects onA.alternate from kiwifruit，and suggested that 43% Lunason and 80% Ethylicin should be used to control pathogen from flowering stage to early stage of kiwifruit development，so as to reduce postharvest disease and fungal infection in kiwifruit development.
