中文摘要:
      为筛选防治火龙果炭疽病(Colletotrichum gloeosporioides)的高效、安全杀菌剂,进行田间药效 试验,结果表明:10% 苯醚甲环唑水分散粒剂1 500 倍液和50% 咪鲜胺可湿性粉剂1 500 倍液对火龙果炭 疽病的防治效果达到77% 以上,其次是CuSO4∶CaO∶H2O 配比为1∶1∶100 的波尔多液,经过3 次施药 后,其防效达到66.67%,与10% 苯醚甲环唑水分散粒剂1 500 倍液、50% 咪鲜胺可湿性粉剂1 500 倍液差 异不显著,因此生产上建议10% 苯醚甲环唑水分散粒剂1 500 倍液和50% 咪鲜胺可湿性粉剂1 500 倍液适 当交替使用防治火龙果炭疽病。由于火龙果花对波尔多液、石硫合剂较为敏感,因此在火龙果生产上应慎 重使用,特别是生殖生长阶段应禁止使用。
英文摘要:
      The field efficacy test was conducted for screening efficient and safe fungicides against Pitaya Anthracnose( Colletotrichum gloeosporioides). The results showed that by spraying 1 500 times 10% difennoconanose WG and 1 500 times 50% prochloraz WP against Pitaya Anthracnose,the control effects reached 77%. Bordeaux mixture( the ratio of CuSO4,CaO and H2O is 1∶1∶100) come second,after three times of application,the control effect of Bordeaux mixture against Pitaya Anthracnose reached 66.67%,which had no significant difference with that of 1 500 times 10% difenoconazole WG and 1 500 times 50% prochloraz WP at the significant level of 0.05 and 0.01. So we could use 1 500 times 10% difenoconazole WG and 1 500 times 50% prochloraz WP alternately to prevent Pitaya Anthracnose in field production. Pitaya was sensitive to lime-suffer and Bordeaux mixture,those two fungicides should be used cautiously in field production ,especially during reproductive growth stage.
