I work with tomatoes in an organic production system. Phytophthora infestans is late blight. Bordeaux mixture (copper sulfate and hydrated calcium sulfate, in various concentrations) has been used successfully, and is organically certified in North Carolina by the
Carolina Farm Stewardship Association. So the answer to your is it an alternative question is yes, but as a protectant only.

Unfortunately, I've not heard of Neoleucinodes elegantalis. Further, it's not listed in the tomato disease compendium (APS Press), nor "Fungi on plants and plant products in the United States", Farr, et al. (this is pretty much the bible for plant pathologists in the
US, also called "the big red book," by plant pathology student everywhere).

What are the symptoms of the Neoleucinodes elegantalis disease? Is there another name for the fungus (older, or newer)?

As I've said I work with different organic amendments (swine manure, composted cotton gin trash, and a rye/vetch green manure) and their effects on soil microbial and nematode communities, soil chemical and physical properties, southern blight control (caused by
Sclerotium rolfsii), and (of course) tomato yield.
If I can do anything for you, let me know. (Keep in mind that I'm a student writing several papers and a thesis so I can graduate in December, if all goes as planned. . ;-)

Later. . .Russ
