摘　　要：柑橘黑斑病菌(Guignarida citricarpa)是欧盟和美国禁止进境的植物检疫性有害生物。近年,柑橘黑斑病成为阻碍我国柑橘出口欧盟的瓶颈,广东梅州名优鲜果——蜜柚出口基地黑斑病也遇到类似情况。为解决在柚子果实采摘前控制和减少柑橘黑斑病对果实的侵染,选择10种杀菌剂在柚子果实上进行柑橘黑斑病田间防控试验。试验结果可以初步确定嘧菌酯、甲基硫菌灵、苯嘧甲环唑等内吸性、具备对病原菌新型作用机制的杀菌剂能够在田间对柑橘黑斑病起到较好的防控效果。Guignardia citricarpa,the causal agent of Citrus Black Spot,is subject to phytosanitary legialateion in European Union and the USA.Recent years,the disease of citrus black spot becomes a obstacle for Chinese citrus fruit export to European Union.The export orchards of high-quality honey pomelos（Citrus grandis） in Meihzhou Guangdong have also met the same problem.For controlling infection of the disease on the peel surface of the preharvest pomelos,10 fungicides were tested in the field.The results of trials showed that azoxystrobin,difenocnazole,and thiophanate-methyl which had.systemic,new mode of action fungicides would control citrus black spot better.
