What it means when plants are rated immune, resistant or susceptible to diseases

by staff

Plants may be resistant to one disease or pest but not another. The label may specify. For example, hybrid tomato plant labels have codes that indicate disease resistance: V for verticillium wilt, F for fusarium wilt, T for tobacco mosaic virus, A for Alternaria leaf spot, N for nematodes, St for gray leaf spot. A tomato cultivar, or cultivated variety, labeled VFN is resistant to some of these problems, but not all.
