柑桔疮痂病是柑桔主要病害之一.据八二年调查市区柑桔疮痂病叶发病率44.21%～73.77%,幼果发病率57.77%～74.79%,常导致落叶、落果、影响树势,降低产量和果品质量.柑桔疮痂病的防治,现常用农药为波尔多液和50%多菌灵可湿性粉剂.果园单独连续喷布波尔多液会导致螨类、蚧类、粉虱类的猖獗,而喷布50%多菌灵可湿性粉剂防治疮痂病效果不及波尔多液好.为此,我们使用40%多菌灵胶悬剂和现行常用农药波尔多液、50%多菌灵可湿性粉剂进行柑桔疮痂病药剂防治试验,现将试验结果整理于后.
Citrus scab is one of the main diseases of citrus.According to the survey of urban areas in 1982, the incidence of citrus scab disease leaves was 44.21% ~ 73.77%, the incidence of young fruit 57.77% ~ 74.79%, often leading to deciduous, deciduous, affecting the tree Potential to reduce production and quality of fruit.Scab disease prevention and treatment of citrus, pesticides are commonly used for the Bordeaux mixture and 50% carbendazim wettable powder orchard Borneol continuous continuous spraying Bordeaux mixture will lead to mites, scale, whitefly Rampant, and spray 50% carbendazim WP prevention and treatment of scab is not as good as Bordeaux solution.To this end, we use 40% carbendazim suspension and the current commonly used pesticide Bordeaux mixture, 50% carbendazim WP Citrus scab disease agent control test, the test results are now sorted out.
