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 controlling pepper phytophthora blight. 【Method】The 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 experiment. 【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 mL/ha, respectively. Both of them had no significant differences to the prevention efficiency(54.83%) of50% dimethomorph WP. 【Conclusion】The photosynthetic bacteria had potential in bio-control of pepper phytophthora blight.
