| 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. |
