不同生物菌剂对设施番茄灰霉病的防效研究

Control Effects of Different Biological Agents Against Facility Tomato Gray Mold Disease

为降低设施蔬菜土传病虫害的发生和减少化学农药施用量,开展了不同生物菌剂对设施番茄灰霉病的防效研究。结果表明,施用生物菌肥的绿色防控技术对番茄灰霉病的防效优于常规防治技术,初次施药后45、52、59 d施用生物菌肥的绿色防控技术处理对番茄灰霉病的防效分别达100.00%、91.23%、87.86%。施用生物菌肥的绿色防控技术处理不仅对设施番茄无不良影响,安全性好,而且还能促进设施番茄植株生长。

In order to reduce the occurrence of soil-borne diseases and pests of facility vegetables and reduce the amount of chemical pesticides,the control effects of different biological agents against facility tomato gray mold disease were studied.The results showed that the green control technology with biological bacterial fertilizer had better control effect on tomato gray mold disease than the conventional farmer control technology,45,52,59 d after first application pesticide,the control effects of green control technology with biological bacterial fertilizer treatment against facility tomato gray mold disease were 100.00%,91.23%,87.86%,respectively.The application of green control technology with biolo-gical bacterial fertilizer not only has no adverse effect on facility tomato,but also can promote the growth of facility tomato.
