I think it can help indeed. Last season Penn State university was
warning about another bad year for late blight in our area. I started
all my plants indoors from seed. Gave plants to many of my neighbors
and not one of these plants were hit with late blight or any other
disease! I think when you buy your plants from a nursery or chain
store, you take the chance that your plants may be diseased when you
take them home. These growers raise their plants on a much larger scale
and in my opinion, it increases the risk of disease spreading
throughout their plants. What do you think?

I've experienced exactly that from the commercial growers seedlings. Last
year was not a good one to get healthy plants.
