Abstract: To screen synergistic effect of the compound of bacterial suspension, antifungal protein of Bacillus licheniformis W10 and chemical germicide on Monilinia fructicola, the experiments were performed by colony diameter inhibited. Results showed that the mixtures of antifungal protein and carbendazim with ratios of 100∶1 could obviously increase the toxicity (SR = 4.32). Therefore, B. licheniformis W10 mixed with some fungicides could be used for biocontrol of peach brown rot.

摘要： 为减少化学药剂的使用，明确生防细菌地衣芽孢杆菌W10与化学药剂复配对桃褐腐病菌Monilinia fructicola抑菌活性的增效作用，采用菌落直径抑制法，检测W10菌液和抗菌蛋白与化学试剂复配的抑菌效果。结果显示，W10抗菌蛋白与化学药剂复配增效显著，与多菌灵100∶1增效作用最大(SR=4.32)。证明生防细菌W10菌液及抗菌蛋白与化学药剂以合适比例复配对桃褐腐病菌的抑制有增效作用，可用于该病害的防治。
