With the widespread occurrence of late blight last season on tomato and potato. There is some new information available from other universities that might be of interest. Dr. Meg McGrath, Cornell plant pathologist on Long Island, has written two articles on managing late blight organically, both of which are available online: Managing Late Blight in Organically-Produced Potato and Managing Late Blight in Organically-Produced Tomato.
Dr. Tom Zitter, also from Cornell, compiled a list of tomato varieties with reported resistance to late blight and early blight that might be helpful: Table of Late Blight and Early Blight Resistant Tomato Cultivars
