摘  要：
【目的】旨在筛选用于桑葚菌核病防治的高效生物制剂,提高桑葚品质。【方法】通过田间试验,选用2×108 CFU/g泰诺木霉菌(WP)、3%中生菌素(WP)、47%春雷·王铜(WP)、3×108 CFU/g哈茨木霉菌(WP)、4%嘧啶核苷类抗生素(水剂)5种生物制剂,每种生物制剂设3个浓度梯度,在桑树初花期、盛花期、谢花期分别用5种不同生物制剂不同稀释液喷施桑树。【结果】5种生物制剂对桑葚菌核病具有不同程度的防效,且同一生物制剂随着药液浓度增加,防效呈上升趋势。【结论】2×108 CFU/g泰诺木霉菌可湿性粉剂300~800倍液对桑葚菌核病防效是69.76%~84.02%,与目前生产中应用的化学药剂腐霉利防效相当,因此可作为桑葚菌核病的防治药剂。

摘  要：
[Purpose]In order to control of mulberry fruit sclerotiniosis and to improve the fruit quality of mulberry, different biological agents were screened out through the control efficiency experiments of biological agent.[ Method] By field experiment, we selected 5 kinds of biological agents, 2×108 CFU/g Trichoderma viride(WP), 3% mesoin(WP), 47% kasugamycin·copper oxychloride(WP), 3×108 CFU/g Trichoderma harzianum(WP), 4% pyrimidine nucleoside antibiotics(water agent), each biological agent with three concentration gradients. Five different biological agents with different diluents were sprayed on the mulberry trees separately at the early flowers stage, full flowers stage and final flowers stage.[Results]Five kinds of biological agents had different control effects on the mulberry fruit sclerotiniosis and the control efficiency rose with the concentration increasing.[Conclusion]2×108 CFU/g tylenol Trichoderma wettable powder diluted with 300–800 times had 69.76%–84.02%, close to the control effect of pythium which is mainly used in biological agents, therefore, it can be used as the prevention and control drug for mulberry fruit sclerotiniosis.
