Abstract:: Selecting five drugs amobam，cuprousoxide，benziothiazolinone，dithane M-45，streptomycin as the materials，the effect of 15 treatmentson controlling leaves moss of Citrus cultivar cv.Huangguogan in the field experiment were studied.The results indicated that the control efficiency of 1 500 times of cuprousoxideto was the best，with control efficiency 85.62%，and it can keep fruit quality of Citrus cultivar cv.Huangguogan better；the control efficiency of 45% amobamthe treatments 800 times，1 000 times，1 500 times and 2 000 times of cuprousoxide were more than 60% without phytotoxicity；the worst control efficiency was streptomycin with three kinds of concentration，and the control efficiency of them were less than 20%；cuprousoxide had a good control effect on leaves moss of Citrus cultivar cv.Huangguogan.
