Garden Safe Take Root Rooting Hormone, Promotes Rooting, Grow New Plants From Cuttings, 2 Ounce

is this item a gel or a powder or what?

Does this product have an expiration date, and if so does it tend to be a year, two years, etc.; does it have an indefinite shelf life? Thanks!

Does this have a fungicide? I can't seem to find any rooting hormone that does.

Can this used on food crops?
