| Abstract: | Objective]To evaluate the field efficacy of oxine-copper 33.5% SC against bacterial gall on waxberry.Method]Different doses of oxine-copper 33.5% SC were set up to carry out field efficacy test on waxberry bacterial gall. The control effect, optimal dosage, duration of efficacy and safety of beneficial organisms to waxberry and non-target were investigated.Result]At the beginning of spring cycle shoot formation,the control rate of oxine-copper 33.5% SC against bacterial gall on waxberry could reach 67.7%-71.3% 26 days after application when used at the dose of 446.7-335 mg/kg, for 3 consecutive times, once 7 days,and oxine-copper 33.5% SC was safety to waxberry and other non target organisms.Conclusion] Oxine-copper 33.5% SC could be used to prevent and control bacterial gall on waxberry. |
