摘要/Abstract

摘要： 采用播前种薯浸液消毒处理法,研究了8种化学药剂在旱地和水旱轮作地对马铃薯早疫病、晚疫病和疮痂病的田间防治效果。结果表明,马铃薯早疫病旱地以500 g/L氟啶胺悬浮剂和50%烯酰吗啉可湿性粉剂的防治效果较好,均高于80%,水旱轮作地以500 g/L氟啶胺悬浮剂的防治效果相对较好,为60.3%;疮痂病旱地以500 g/L氟啶胺悬浮剂和75%百菌清水分散粒剂的防治效果较好,均高于80%,水旱轮作地以75%百菌清和80%代森锰锌可湿性粉剂的防治效果相对较好,均高于60%;种薯浸液消毒处理对马铃薯晚疫病的防治效果较差。与水旱轮作地相比,8种化学药剂在旱地对3种主要病害的防治效果整体较好。

Abstract: By the method of dipping sterilization of pre-sowing seed potato tubers, the effects of 8 chemical fungicides on potato early blight, late blight and scab were researched in the dry farmland and rotation paddy-upland crop field. The results suggested that the control effects of 500 g/L fluazinam suspension agent and 50% dimethomorph wettable powder on potato blight were better than others, which was higher than 80% in dry farmland. Besides that, the control effects of 500 g/L fluazinam suspension agent was relative better than others in the rotation paddy-upland crop field, which was 60.3%; The control effects of 500 g/L fluazinam suspension agent and 75% chlorothalonil water dispersible granule were better than other fungicides on potato scab,which were higher than 80% in dry farmland. Besides that, the effects of 75% chlorothalonil water dispersible granule and 80% mancozeb wettable powder were relative better than other funigicides and the effects were higher than 60%; The effects of dipping sterilization of seed potato tubers with 8 fungicides on potato late blight were not good. The overall effects of every fungicides on 3 main potato diseases were higher in dry farmland than in the rotation paddy-upland crop field.
