Abstract:

Tomato spotted wilt virus (TSWV) and potato virus Y (PVY) are the main virus diseases of tobacco in Yunnan, the research aims to screen highly effective agents to control the virus on tobacco, thereby reducing the economic losses of tobacco. Through field plot tests, the control effects of 1% lentinan aqueous solution, 3% harpin protein, 5% amino oligosaccharide water and 2% cytosintetidemycin on TSWV and PVY were investigated. The results showed that the four agents had certain preventing and control effects on TSWV and PVY. The control effect of 1% lentinan aqueous solution, 3% harpin protein, 5% amino oligosaccharide water and 2% cytosintetidemycin was 31.11%-39.90%, 54.34%-59.91%, 8.69%-38.21% and 22.75%-43.32% on TSWV, respectively, and 55.08%-71.06%, 68.10%-82.24%, 37.76%-55.36% and 58.07%-68.86% on PVY, respectively. Among them, the control effect of 3% harpin protein was the best, which was over 50% and 60% on TSWV and PVY, respectively, followed by that of 2% cytosintetidemycin, which was over 22% and 58% on TSWV and PVY, respectively.

Key words: tobacco, virus inhibitors, tomato spotted wilt virus, potato virus Y, harpin protein, cytosintetidemycin, control effect
