肥料和农药协同作用防治烟草根结线虫病研究

Controlling Tobacco Root-knot Nematodes by Fertilizer and Pesticide Synergy

通过田间随机区组试验探讨农药和肥料协同对烟草根结线虫病的防效,研究发现0.5%阿维菌素颗粒剂和25%阿维·丁硫水剂的防效显著,防效分别是28.0%和24.1%,有机肥、无机复合肥与0.5%阿维菌素颗粒剂协同作用可以增强阿维菌素的防效,减轻根结线虫对烤烟生长的影响,提高烤烟产量和质量,增加烤烟收益。研究结果建议在烤烟生产上整合农业措施和化学防治具有积极的生产和生态意义。

Synergism between pesticide and fertilizer in controlling root-knot nematodes was investigated by field randomized block test. The results showed that the best control ettlciency was shared by 0.5 % abamectin and 25 % mixed agent （ abamectin and carbosulfan）, and was 24.1% and 28.0 % respectively. The positive effect was found by synergism between pesticide and fertilizer in controlling root-knot nema- todes. The economic benefit and agricultural benefit were gained by controlling root-knot nematodes. The results suggested that the agricul- tural and ecological benefit could be gained through integration of agricultural practice and chemical technology in controlling root-knot nematodes.
