Scabs caused by Venturia carpophila greatly reduce the quality of the fruits of the Japanese apricot (Prunus mume) when the disease is not properly managed. The disease produces a superficial blemish that is unlikely to affect the overall yield of processed fruit, but reduce the value of fruit intended for the fresh market. Incidence rates of scab at sprayed and unsprayed orchards range from 0% to 21.5% and from 30.2% to 100%, respectively, in the major cultivation regions of Jeonnam Province during the growing season of 2009. The trends in disease progress were quite similar, regardless of regions, and cultivar Namgo was relatively less damaged by scab compared to cultivar Cheonmae among the tested Japanese apricot cultivars. The fruits on branches 1.5 m above the infected Japanese apricot trees and the stem-end parts of the infected fruits were more severely damaged by scabs, possibly because of rain and run-off facilitate dissemination of conidia of V. carpophila and subsequent infection of the fruits or branches. The conidia of V. carpophila were dispersed from March 24 to April 26 in 2010, and more conidia were dispersed from 2-year-old branches than 1-year-old branches. Since the control efficacies were higher than 90% after more than two applications of Trifloxystrobin WG at 10-day-intervals from mid April, it is that effective fungicides be applied at least two times at 10-day-intervals from the middle of April to manage scabs of Japanese apricot in orchards.

韩国日本杏Sc疮的流行病学特征

引起结痂黑星carpophila大大降低了日本杏的果实品质（梅）当疾病得不到适当处理时。该病产生的浅表瑕疵不太可能影响加工水果的总产量，但会降低用于新鲜市场的水果的价值。在2009年生长季节，全南省主要种植区，喷雾果园和未喷雾果园的sc疮发病率分别为0％至21.5％和30.2％至100％。疾病进展的趋势非常相似，不论哪个地区，在测试的日本杏品种中，Namgo品种的结ab损害相对于Cheonmae品种都相对较小。在受感染的日本杏树上方1.5 m的树枝上的果实以及受感染果实的茎端部分受结ab的破坏更严重，可能是因为下雨和径流促进了分生孢子的传播。V. carpophila及随后感染的果实或分支。分生孢子五carpophila在2010年进行了分散从3月24日至4月26日，和更多的分生孢子从2年生枝条分散于1岁的分支机构。由于从4月中旬开始间隔10天间隔两次应用Trifloxystrobin WG的防治效果高于90％，因此从4月中旬至4月中旬间隔10天间隔至少两次应用了有效的杀菌剂。在果园里管理日本杏sc。
