Summary Efficacy of oxyn copper wettable powder (flowable) diluted to 1,250 ppm to the scab desease on Japanese pear sprayed just before sprout was studied, as an alternative fungicide to lime sulfer and machine-oil·oxyn-copper. As the result, oxyn copper spray just before sprout suppressed the occurrence of scab desease in early growing stage, and raised the efficacy of DMI fungicide sprayed at early growing stage to the scab desease. The cost of oxyn copper diluted to 1,250 ppm was quarter than the cost of lime sulfer diluted to 142, 857 ppm, and one sixth than the cost of machine-oil·oxyn-copper diluted to 2,500ppm. Thease results show that oxyn copper spraying just before sprout on Japanese pear is important for efficiency advancement of the scab desease control on Japanese pear.
