Hi, you are following some good "best practices" for dealing with early blight. We would only add removing lower leaf branches (up to 2 ft. from soil) beginning once plants are well-established and trying some of the cultivars from the NC State University tomato breeding program with moderate levels of resistance to the disease, including 'Mountain Magic,' 'Mountain Supreme,' and 'Mountain Merit.'

Fixed copper fungicides work best if started early in the season prior to symptom development.
