摘要
1985—1989年研究结果表明:14%胶氨铜水剂是目前防治柑桔溃疡病较理想的杀菌剂,效果略超过常规农药波尔多液;溃疡病药剂防治适期是春、夏、秋梢的梢长分别为4—5、6—7、5—6cm 时,以及果实横径为0.8—1.0、1.8—2.0、2.8～3.0cm 时。重病园用单一防治措施无法奏效,综合防治可有效地降低发病程度,提高果实产量、品质及增加经济效益。
This study was carried out during 1985-1989.Results demonstratedthat Jaoantong 14% AS was an ideal bactericide for citrus canker atpresent.The optimum spraying periods for control of the canker werethat when the spring,summer and autumn shoots were 4-5cm,6-7cm and5-6cm in length,and when the fruit sizes were 0.8-1.0cm,1.8-2.0cm and2.8-3.0cm in cross diameter,respectively.In seriously diseased orchards,a single control method was uneffective,but the integrated manage-ment resulted in reduction of morbility,increase of yield,quality andeconomic benefit as well as.
