Abstract：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．
