摘要
[目的]测定矿物油对3种无机铜杀菌剂防治柑橘疮痂病和全爪螨的增效作用。[方法]采用喷雾法测定无机铜杀菌剂单独使用及与矿物油混用的田间药效。[结果]矿物油与铜制剂混合使用后,77%氢氧化铜可湿性粉剂、53.8%氢氧化铜可湿性粉剂和30%碱式硫酸铜悬浮剂对疮痂病的平均防治效果分别增加了28.25%、20.19%和16.79%;对全爪螨则分别增加73.37%、51.47%和91.95%。[结论]矿物油不仅对3种铜制剂防治疮痂病有增效作用,也能有效抑制其对全爪螨的诱发效应。
[Aims] The study aims to verify the synergistic effect of mineral spray oil on three inorganic copper fungicides for control of citrus scab, Elsinoe fawcettii, and its role to suppress the fungicide-induced effect on the growth of citrus red mite, Panonychus citri. [Methods] The field efficacy was conducted by using praying to study the effect of three inorganic copper fungicides alone and mixed with mineral oil on the prevention and control E. fawcettii and P. citri. [Results] The results showed that oil significantly enhanced the efficacy of all of the fungicides for control of E. fawcettii, with increase of 28.25, 20.19 and 16.79%, and 73.37, 51.47 and 91.95% of P. citri, being observed for 77% and copper hydroxides 53.8% WP, and copper dihydroxosulphate 30% SC, respectively. [Conclusions] It suggested that mineral spray oil not only has synergistic effect on the above three copper fungicides against E. fawcetti,but also could effectively suppress the fungicides-induced effects on the growth of P. citri.
