摘　　要：2014年7、8月份,调查了河北省保定、石家庄等7个苹果主产地区苹果园枝干轮纹病的发生和防治情况。结果表明：河北省苹果枝干轮纹病发生普遍且严重,苹果枝干轮纹病总体发病率为76.26%,病情指数63.70。不同地区间苹果枝干轮纹病的发生情况存在一定差异,承德和张家口地区发病程度最轻,其次为保定地区,其他4个地区受害严重,发病率均达到80%以上,病情指数均高于70。随着树龄的增大,枝干轮纹病危害加重,发病率和病情指数均提高,0～5年小树发病较轻,发病率44.71%,病情指数33.55;而16年以上果树,发病率高达100.00%,病情指数98.53。不同品种苹果枝干轮纹病发生情况不同,＂红星＂、＂富士＂和＂王林＂发病最严重,其次是＂嘎啦＂和＂斗南＂,＂国光＂发病较轻。在枝干轮纹病的化学防治中常用药剂有多菌灵、石硫合剂和戊唑醇。From July to August in 2014,the occurrence and control status of Botryosphaeria canker of apple were investigated in orchards located in seven major apple production areas in Hebei province.The results showed that the incidence of this disease in general was about 76.26%,disease index was 63.70.The occurrence of the disease varied among different regions.Comparatively,the occurrence of the disease were the lightest in Zhangjiakou and Chengde,followed by Baoding,the others were serious.The incidence rate reached 80%,the disease index was higher than 70.The older the tree,the more severe the disease.The incidences and the disease index were 44.71%and 33.55,100.00%and98.53 for the trees at the age of 0-5and more than 16,respectively.There were significant differences in occurrence of the disease among the main cultivars.‘Red Star＇,‘Fuji＇and‘Wanglin＇were the most serious disease,followed by the‘Gala＇and‘Dounan＇,‘Guoguang＇were the lightest.Among the chemicals used to prevent Botryosphaeriacanker of apple,carbendazim,lime sulphur and tebuconazole were the most popular fungicides.
