摘要
为探索烟草白粉病的绿色、安全防控新途径,消除其化学农药防治的安全隐患.试验以植物"秾皛"销粉剂(生物制剂)和3种化学农药(36%甲基硫菌灵悬浮剂、12.5%腈菌唑微乳剂和25%三唑酮可湿性粉剂)进行田间防效试验.结果表明,于大田烤烟白粉病发病始期或发病中期开始喷药,喷施2~3次后投资回报率可达291.8%~315.4%.植物"秾皛"销粉剂防效可达95.9%以上,高于其他3种化学农药平均防效4.5~10.5个百分点,且持效期长,投资回报率最高.由此说明,喷施植物"秾皛"销粉剂可以有效、持久地控制烟草白粉病的危害,可作为优质烟叶生产的备选措施之一.
In order to explore a new way of green and safe prevention and control of tobacco powdery mildew and eliminate the potential safety hazards of chemical pesticide control.The field experiment was carried out with the biological agent of “Nongxiao” powder eliminate and three chemical pesticides of 36% thiophanate methyl suspension, 12.5% nitrile azole microemulsion and 25% Triadimefon wettable powder.The results showed that the return on investment could reach 291.8%—315.4% after spraying 2—3 times in the beginning or middle stage of powdery mildew in the experimental field. Among them, the control effect of the biological agent of“Nongxiao”powder eliminate could reach more than 95.9%, which was better than the average control effect of the other three chemical pesticides by 4.5—10.5 percentage, with a long duration and the highest return on investment. The above research showed that spraying biological agent of “Nongxiao”powder eliminate could effectively and permanently control the harm of tobacco powdery mildew, and could be used as one of the alternative measures for the production of high-quality tobacco leaves.
