用多功能植物杀菌防病促长剂植壮素进行防治烟草花叶病的试验，结果表明：植壮素对烟草花叶病有较好的防治效果，防效率为１９．１％～５１．３％；烟草植株高度、单株叶片数和叶片鲜重分别增加 ７．９％～３６．９％，１３．７％～３７．８％和 １４．３％～３５．７％，烟草增产 ６．４％～２４．３％，烟叶品质提高，每公亩增加收入３２２．０～１２３７.３元．

With multi-functional plant antisera and antiproliferative actinomycin phytocide for controlling tobacco mosaic disease, the results showed that: phytocide against tobacco mosaic disease have a better control effect, the anti-efficiency was 19.1% ~ 51. 3%. Tobacco plant height, number of leaves per plant and fresh weight of leaves increased 7.9% -36.9%, 13.7% -37.8% and 14.3% -35.7% .4% ~ 24.3%, improve the quality of tobacco, an increase of income per acre 322.0 ~ 1237.3 yuan.
