Control effect of phytogenic VFB-Ⅰagainst tobacco mosaic virus disease
摘要
Abstract
Effect of VFB-I on tobacco mosaic virus (TMV) was evaluated with anti-TMV activities tested in vitro by local lesion. Protection and treatment efficiencies of VFB-I on TMV were evaluated by pot experiment and field plot trials. Results showed that VFB displayed significant inactivation on TMV with inhibition rate of 82.75% after mixing VFB with TMV for 0.5 h. Infection and replication of TMV to Nicotiana glutinosa were also inhibited by VFB-I, with inhibition rate of 69.80% and 54.06%, respectively. Pot experiment showed that protection efficiency of VFB-Ⅰagainst TMV disease was 70.24% and remedial efficiency was 35.71% by spraying with VFB-Ⅰ diluent of 1:100. In field trials, protection efficiency of VFB-Ⅰdiluent of 1:400 on TMV disease was higher than that of VFB, but equivalent to that of 20% moroxydine+cupric acetate WP at the same concentration. The remedial effect of VFB-Ⅰ(diluent of 1:200) was much stronger than that of 20% moroxydine+cupric acetate WP (diluents of 1:400) and VFB (diluents of 1:200). VFB-Ⅰ showed higher anti-TMV activity indicating that it is effective in controlling TMV disease.关键词
