Is it "Agri-" or "Agro-"?

Sign seeking a Lease or Joint Venture partner, Kelowna

Signs are intended to convey information, and a sign like this would seem to be a search for a business partner. The problem with this sign is that the word should be "Agri-Tourism" not "Agro-Tourism".

While both "agri-" and "agro-" are prefixes used to denote agriculture, "agri-" seems to be in more common usage in Canada.

But, readers of the sign will probably know what the firm is intending and with any luck they will find a partner.
