There are a couple of things that you can do to reduce the effects of blight. Try rotating your tomato plants to different areas of the garden and then grow different crops where the tomatoes were previously. This helps reduce the buildup of a particular organism that may fluorish with one crop being grown continuously in one area. The other way to control blight and other diseases is to solarize the affected garden area. Solarization involves removing plant material, rocks, sticks, etc. from the site and then covering the affected area (or the whole garden) with black plastic and sealing the edges of the plastic with soil. Let sunlight heat the soil for about 5-7 days. The soil temperature will get quite hot, which will kill off microorganisms. You can then remove the plastic and proceed with planting your garden.
