摘要
[目的]筛选水稻穗颈瘟的防治药剂,为水稻生产提供参考。[方法]通过小区试验测定了7种杀菌剂对水稻穗颈瘟的防治效果。[结果]在水稻破口初期施药1次,75%三环唑可湿性粉剂(WP )和27%三环·己唑醇悬浮剂(SC )对穗颈瘟的防治效果较好,防效分别达74.34%和78.03%,其他5种药剂防效一般。[结论]从延缓抗药性发生和具有治疗作用的角度看,建议在生产中推广应用27%三环·己唑醇SC 防治穗颈瘟。

(Huai’an Station of Plant Protection and Quarantine, Huai’an, Jiangsu 223001) Abstract ;[Objective] Fungicides for controlling rice blast were screened out for provide reference for production of rice.[Method] The control effects of seven fungicides against rice blast were detected through plot test.[Result] 75% Tebuconazole WP and 27% Tebuconazole·hexaconazole SC applied once at the beginning of rice booting heading had good control efficacy on rice blast, with control efficacy of 74.34% and 7803%, while the other five agents had bad control
efficacy.[Conclusion] According to delaying resistance and curative effect, it is suggested that 27% Tebuconazole·hexaconazole SC can be applied to control rice blast.
