We don't have issues with fusarium (knock, knock), but we have a terrible problem with early blight and septoria in our community garden, where spraying isn't allowed. I know the rootstocks don't offer any help directly for foliage diseases, but I've grafted most of my plants this year and last and I believe I've been seeing significant benefit from the extra vigor of the rootstock plants (Maxifort and a few Colosus) in helping my plants grow vigorously enough to stay ahead of the infection. Seems worth trying if you can actually use the built-in resistance.
