Chitosan, appears to be lots of products available now. Curious if there’s a closeted band of use within the pumpkin community? First started writing about Unobtanium many years ago. There are many published reports out there touting its usage.

Great thanks Andy, I’m using some Amazon, Chitosan COS type product. The research papers and articles sure make great claims. I’m mostly concerned with Nematodes and soil issues like Fusarium as I don’t rotate. Not sure if it’s legal in Ontario or controlled. Any other effects are a bonus. I had great results the last time several years ago.

I'd have to look, but I think it's only something like 1mL / gal

Here is a good label link,


FYI, when I first heard about Unobtainium many years ago and was finally told what it was....it was Lithovit.
