摘要: 烟草根结线虫已成为攀枝花市烟区烟草的主要病害,对烟草造成严重的产量损失。为了筛选高效、安全的生物杀线虫剂,2017-2018年在攀枝花市仁和区干坝子村进行了4种不同生物杀线剂对烟草根结线虫防治的田间试验,通过防治效果、二龄幼虫虫口减退率校正防效、增产率等指标综合评价了供试生物制剂对烟草根结线虫的药效。结果表明:‘永卫?168’水剂在防治效果、二龄幼虫虫口减退率校正防效、增产率方面综合表现最好,用药后120d对烟草根结线虫的防效为62.11%、虫口减退率校正防效为81.05%、增产效果高达53.08%,说明‘永卫?168’ 水剂在烟草根结线虫防治中具有较好的推广应用前景。

Abstract: Root-knot nematode has become the major threat to tobacco in Panzhihua, and caused serious yield loss. To screen biological agent with high efficiency and safety, a field experiment was conducted to determine the effect of four biological agents against tobacco root-knot nematode in Ganbazi, Renhe during 2017-2018. The efficacy was evaluated comprehensively through control efficacy, the correction control efficacy of the decline rate of the second- stage juveniles and the yield- increasing efficiency. The results showed that ‘Yongwei?168’agent gained the highest comprehensive performance with the control efficacy of 62.11%, the correction control efficacy of the decline rate of the second-stage juveniles of 81.05% and the yield increase effect of 53.08% 120 days after the treatment. Therefore,‘Yongwei?168’agent has a good application prospect on controlling tobacco root-knot nematodes.
