TYLCV disseminated by Tobacco whitefly...
Even if you control the tobacco whitefly properly from earlier, you can reduce the incidence of TYLCV a lot.
Since using the virus tolerance seed one day, the plants have been able to grow without worry about the incidence of TYLCV.
But, it has been recently (in 2015*) reported that TYLCV can be disseminated by the seed.
