摘　　要：为评价植物源甘油酯作为助剂对氢氧化铜防控柑橘溃疡病的减量增效作用,试验比较了46.1%氢氧化铜水分散粒剂单独使用、植物源甘油酯乳剂300倍液+46.1%氢氧化铜水分散粒剂2143倍液(减量30%)、植物源甘油酯乳剂300倍液+46.1%氢氧化铜水分散粒剂3000倍液(减量50%),对柑橘溃疡病的防治效果。结果表明:减量30%的处理对柑橘溃疡病的防治效果最好,对叶片的防治效果显著高于减量50%和不减量的处理,3个处理间对果实的防治效果无显著差异。综合比较,采用喷施植物源甘油酯助剂300倍液+46.1%氢氧化铜水分散粒剂2143倍液的处理,可以提高氢氧化铜对柑橘溃疡病的防控效果,同时减少其使用量,值得在生产上推广应用。To evaluate the decrement and synergism effects of botanical glyceride as an adjuvant on copper hydroxide controlling citrus canker,the control effects of spraying copper hydroxide 46.1%WG(1,500×dilution,no reduction of dosage),botanical glyceride EC(300×dilution)+copper hydroxide 46.1%WG(2,143×dilution,30%decrement),botanical glyceride EC(300×dilution)+copper hydroxide 46.1%WG(3,000×dilution,50%decrement)on citrus canker were compared.The results show that the control effect of botanical glyceride EC(300×dilution)+copper hydroxide 46.1%WG(2,143×dilution,30%decrement)was the best,whose efficacy for the leaves was significantly higher than that of the other two treatments;there were no significant differences of the efficacy for the fruits between the three treatments.In sum,spraying botanical glyceride EC(300×dilution)+copper hydroxide 46.1%WG(2,143×dilution)could improve the control effect of copper hydroxide on citrus canker,and reduce its use,it is worth promoting and applying in production.
