I haven't been able to find a reference to any commercial items, but I heard that NASA has developed astronaut's socks and underwear with metallic silver threads woven into the fabric.

Didn't know it was used as a weed killer, but cooper sulfate is used often in farming to control fungi. I've used it on my pumpkin and squash fields before. I know several onion farmers us it on onions. BTW- I thought it turned your skin blue.
