I agree with all the statements. For next year be sure to clean up the garden space of all debris (leaves, stems, fruit, etc.). Since most tomato diseases tend to be soil borne, blight is one of those, avoid soil being splashed onto the plants by having a good mulching program. Mulch also keeps the plant cooler and retains water so less watering is necessary. I use newspaper as a base and then put a 6-8 inch layer of straw. There are lots of choices for mulch, so that would be a good research project this winter.
Avoid overhead watering, water the soil at the base of the plant. Rain is an overhead waterer and that is pretty difficult method to control. That is where the mulch will help keep the soil from splashing up on the leaves. It is also difficult for many to move tomatoes to another area if the garden space is limited. A good sanitation program will help out a lot.
Some say choose disease resistant varieties, but that only puts off the inevitable for a few days or maybe weeks. No tomato variety is immune to disease, so choose the varieties you want and practice the best methods of avoidance: no overhead watering, sanitation, a good mulching program, making sure there is airflow at the base of the plant by staking or caging and using a spray if absolutely necessary to save a plant.
Good luck and good gardening.
