A possible new treatment for fungus on tomato plants

[Elliot]

I was at a medical conference this past weekend. There is a product made from grapefruit seeds that is being used to treat fungus affecting the skin. Originally it was developed to treat fungi affecting fish hatcheries. It is non toxic.

I ran the idea of testing this on tomato plants affected by fungi. The owner was quite receptive to the idea. Who can I refer him to who can help test this product on tomato plants?
