A Comparison of Disinfectants to Prevent Spread of Potyviruses in Greenhouse Tomato Production

Fig. 2. Comparison of percent infection between serial and direct inoculation of each of 8 plants. Plants in each block were numbered 1 through 8, with plant 1 being the first plant inoculated and plant 8 the last. Black bars indicate percent infection of each plant during serial inoculation, in which blade was dipped in inoculum prior to inoculating plant 1, and not dipped or sterilized during sequential inoculation of plants 2 through 8. Hashed bars indicate percent infection of each plant during direct inoculation, in which blade was dipped in inoculum prior to inoculation of each plant.
