Do Super Sweet 100 Plants Have Good Disease Resistance?

I searched Super Sweet 100 Plants on YourHomify, though I am worried about the issue of diseases like blight or mildew. Is it enough resisting Super Sweet 100 Tomatoes, or am I in need of the next stage of treatment (staking, pruning, spraying)? Would I avoid a premature viability by preventing the seeds and planting the Super Sweet 100 Plants ready? Did you have any issues with those people who planted the Super Sweet 100 Seeds, or were the plants healthy? Other recommendations to be made before planting?
