摘要
本文从植物源农药制剂对病毒和烟草植株的作用两个方面探讨了天然植物性农药ＭＨ１１－４对烟草花叶病的防治作用，结果表明ＭＨ１１－４对ＴＭＶ和ＣＭＶ有强烈的体外钝化作用，并能明显地抑制烟株体内ＴＭＶ和ＣＭＶ的增殖；同时，该药剂还能显著提高烟草植株体内过氧化物酶的活性。
The study of the effects of plant pesticide MH11 4 on TMV and CMV which caused tobacco mosaic disease revealed that not only they were effective on the inactivation of TMV and CMV in vitro, but also effective on the inactivation of TMV and CMV in vivo, i.e.in the living tobacco plants. Furthermore, when the living tobacco plants were sprayed with MH11 4, an increase of peroxidase activity was observed. It suggests that MH11 4 is a virus resistance inducer for tobacco.
