Field Efficacy of 33.5 Oxine-copper SC against Leaf Spot Disease on Waxberry

摘要

Leaf spot disease seriously affects the yield and quality of waxberry, but there is no registration agent for prevention and control of the disease. The field trials showed that the control efficacy of 33.5% oxine-copper SC against leaf spot disease on waxberry reached above 74% when used at the dosage of 167.5-223.3 mg/kg. 33.5% Oxine-copper SC could be used to control leaf spot disease on waxberry.
