室内实验分别以TMV和CMV的枯斑寄主心叶烟和苋色黎为测试寄主，采用全叶法接种，接种前和接后分别对接种叶片半叶法涂施几种病毒防治刘。结果表明．3．85％病毒必克无论在接种前还是接种后涂施对TMV和CMV都有较好的抑制效果，接种前在心烟上和苋色黎上抑制率分别为88．85％和86．77％，接后抑制率分别为82．77％和78．57％；植病灵和病毒A在接种前涂施对TMV和CMV均有较好抑制效果，几乎都超过75％；接种后涂施抑制效果较差。大田实验选用3种植物病毒病防治剂和2种杀蚜剂对烟草花叶病进行防治，结果表明，病毒防治剂病毒必克、植病灵、病毒A均对花叶病有较好的预防效果．防效依次为3．85％病毒必克72．61％、1．5％植病灵60．8％、20％病毒A59．00％，其中病毒必克防效最好，可达70％以上，并且有一定治疗作用，其它2种病毒防治剂对花叶病无治疗作用；杀蚜剂氧乐果、抗蚜威对花叶防效分别为12．76％和11．42％。
In laboratory experiments, the main leaf tobacco and amaranth of the host of TMV and CMV were used as the test host, and the whole leaf method was used to inoculate them. Before and after inoculation, several viruses were applied to prevent and cure Liu. The results show. 3.85% of the virus will be grams before and after inoculation of vaccination on both TMV and CMV have a good inhibitory effect, before inoculation on heart smoke and amaranth on the inhibition rates were 88.85% and 86.77 %, Followed by the inhibition rate was 82.77% and 78.57% respectively; Phytophthora and virus A had better inhibitory effect on both TMV and CMV before inoculation, almost over 75%; after inoculation Suppression effect is poor. Field experiments using three kinds of plant virus disease control agent and two kinds of aphides on tobacco mosaic disease prevention and control, the results show that the virus prevention and treatment of the virus will be grams, planting Ling, A virus mosaic disease prevention are better effect. The control effects were 3.85%, 72.61% for virus, 60.8% for 1.5%, 20% for virus A59.00% , And there is a certain therapeutic effect, the other two kinds of virus control agents have no therapeutic effect on mosaic disease; the aphides agent Omethoate and pirimicarb control effects on mosaic are 12.76% and 11.42%, respectively.
