摘　　要：小麦赤霉病是小麦生产中最主要的病害之一,严重影响小麦的产量和品质。漯河地区位于河南省中南部,属于北亚热带向暖温带过渡区,是小麦生产的特殊生态地区。近几年,漯河地区赤霉病的发生频率和危害程度均有所增加。本文探讨了漯河地区小麦赤霉病的发生原因,包括主栽品种易感赤霉病、菌源数量多、气候条件利于赤霉病发生、田间管理措施不佳、种植户应灾能力弱等方面,并介绍了常见防治小麦赤霉病的化学药剂,如多菌灵、戊唑醇、戊唑醇·咪鲜胺、氰烯菌酯、丙硫菌唑等,提出了选择不同作用机理的药剂轮换使用或者混配使用的建议,以期为小麦赤霉病的防控提供参考。Wheat scab is one of the most important diseases in wheat production, which seriously affects the yield and quality of wheat. Luohe area is located in the middle and south of Henan Province, which belongs to the transition zone from north subtropical zone to warm temperate zone. It is a special ecological area for wheat production. The occurrence frequency and damage degree of scab have increased in recent years. In this paper, the causes of wheat scab in Luohe area were discussed, mainly including that the main cultivars were susceptible to scab, the number of bacterial sources was large, climatic conditions were favorable to the ocurrence of scab, the field management measures were not good, and the farmers′ ability to cope with the disaster was weak. The common chemical agents for the control of wheat scab were analyzed, such as carbendazim, tebuconazole,tebuconazole·prochloraz, phenamacril, prothiazole, etc. The suggestions were put forward for selecting agents with different action mechanisms to be used alternately or mixed, in order to provide reference for the prevention and control of wheat scab.
