研究在烤烟漂浮育苗中,TMV通过营养液途径侵染烟苗发病、通过剪叶传播扩散该病和药剂防治该病情况。营养液中污染TMV、剪刀上带有TMV和病、健烟叶接触摩擦都是该病侵染、扩散的有利途径,对剪叶剪刀用肥皂水、漂白粉或毒消等消毒2min能有效预防该病在剪叶途径中的传播。24%毒消水乳剂、0.5%OS-施特灵水剂在病毒侵染烟苗之前施用有一定的预防作用。
In flue-cured tobacco seedlings, TMV infects tobacco seedlings through the nutrient solution, and spreads the disease and medicament through the cut leaves to prevent and control the disease. TMV contaminated nutrient solution, scissors with TMV and disease, smoking tobacco leaf contact friction are infected with the disease, the proliferation of a favorable way to cut leaf scissors with soap water, bleach or poison disinfection 2min can effectively prevent the disease Spread in the leaf-cutting approach. 24% Poisoned water emulsion, 0.5% OS-Sting Agent solution before the virus infection of tobacco seedlings have a certain preventive effect.
