Re: Blight

Dear M. Take a sample of the diseased tomato to your local University
cooperative extension office. We have a farm advisor in our office that
deals exclusively with vegetables for commercial growers. He will help with
backyard gardeners also. You need to find out if it is in fact blight and
it can be serious.  Or it may not be. Get it identified so you will know
how to proceed. We are getting some early blight,alternaria, here in
Northern California.
