| 摘 要： | [目的]研究光合细菌对辣椒疫病的田间防治效果,为光合细菌应用于辣椒疫病防治提供科学依据和生防资源.[方法]以3个光合细菌菌株PSBCS、PSB06和PSB 13-2-2为试材,以化学药剂50％烯酰吗啉可湿性粉剂为阳性对照,等量清水为阴性对照,采用田间小区试验,研究光合细菌菌剂对辣椒疫病的防治效果.[结果]PSBCS、PSB06和PSB 13-2-2对辣椒疫病均具有一定的防治效果,其中PSB06用量为7500 mL/ha时对辣椒疫病的防治效果最好,相对防效达45.80％; PSB 13-2-2用量为3750 mL/ha时次之,相对防效为44.67％;两处理的相对防效均略低于50％烯酰吗啉可湿性粉剂处理（防效为54.83％）,但差异均不显著.[结论]光合细菌具有防控辣椒疫病的应用潜力.

| Abstract: | [Objective]The prevention efficiency of photosynthetic bacteria （PSB） against pepper phytophthora blight was investigated to provide scientific references and bio-control resources for using hotosynthetic bacteria in preventing and con- trolling pepper phytophthora blight. [MethodlThe prevention efficiency of PSBCS, PSB06, PSB13-2-2, 50% dimethomorph WP （positive control） and equivalent water （negative control） to pepper phytophthora blight was tested by field plot experi- ment. [Result]The prevention efficiency of PSB06 and PSB13-2-2 were 45.80% in dosage of 7500 mL/ha and 44.67% in dosage of 3750 mlJha, respectively. Both of them had no significant differences to the prevention efficiency （54.83%） of 50% dimethomorph WP. [Conclusion]The photosynthetic bacteria had potential in bio-control of pepper phytophthora blight. |
