Disease resistant vegetable plants
We don't have local vegetable suppliers to recommend regarding disease resistant plants. Take a look at the Cornell Website for more information on vegetable varieties and disease resistance. Once you have this information you may be able to ask the nursery or grower if these vegetables are available. Also, some tomato varieties may have small tags that list diseases they are resistant to. Many vegetables do not.
You did not mention what vegetables you are trying to grow and the diseases they are susceptible to. You will have to look at the common problems of the crops and how to deal with them. Look at each Vegetable Profile for more information on common problems/diseases http://extension.umd.edu/hgic/plants/vegetable-crops
You can also look in seed catalogs for disease resistant plants. Take a look at our recommended list of Vegetable Cultivars for suppliers. Keep in mind that "disease resistant" does not mean "immune." http://extension.umd.edu/sites/extension.umd.edu/files/_images/programs/hgic/Publications/HG70_Recom...
