摘要
为探究寡糖·链蛋白和噻虫嗪组合对番茄黄化曲叶病毒病的防控效果,选用6%寡糖·链蛋白可湿性粉剂、25%噻虫嗪水分散粒剂及6%寡糖·链蛋白可湿性粉剂+25%噻虫嗪分散粒剂对番茄黄化曲叶病毒病进行田间防治试验。结果表明:25%噻虫嗪水分散粒剂灌根显著降低了烟粉虱虫口数;6%寡糖·链蛋白可湿性粉剂喷施+25%噻虫嗪水分散粒剂灌根处理效果最好,番茄黄化曲叶病毒发病率和病情指数显著低于空白对照,防控效果为74.25%,番茄株高、叶长、叶宽、SPAD值、氮含量、叶片净光合速率(Pn)及产量均显著高于对照,比对照增产52.82%。综上所述,6%寡糖·链蛋白可湿性粉剂和25%噻虫嗪水分散粒剂组合使用可有效防控番茄黄化曲叶病毒病和烟粉虱的发生,达到增产增效的目的。
In order to explore the prevention and control effect of oligosaccharide·chain protein and thiamethoxam combination on tomato yellow leaf curl virus disease,field experiment about controlling tomato yellow leaf curl virus disease was carried out by selecting and using 6%oligosaccharides·chain protein WP,25%thiamethoxam WG and 6%oligosaccharides·chain protein WP+25%thiamethoxam WG.The results showed that root-irrigation of 25%thiamethoxam WG could significantly reduce the population of Bemisia tabaci,root-irrigatioon treatment of 6%oligosaccharides·chain protein WP+25%thiamethoxam WG had the best effect.The morbidity and disease index of tomato yellow leaf curl virus were significantly lower than that of the contrast.The control effect was 74.25%.The plant height,leaf length,leaf width,SPAD value,nitrogen content,net photosynthetic rate of leaves(Pn)and yield of tomato were all significantly higher than those of the contrast,increasing by 52.82%.In conclusion,the combined use of 6%oligosaccharides chain protein WP and 25%thiamethoxam WG can effectively prevent and control tomato yellow leaf curl virus disease and ocurrence of bemisia tabaci;and achieve the purpose of increasing yield and efficiency.
