Reno, Nev.-Itronics Metallurgical Inc. announced that it will begin the process of registering its new GOLD’n GRO Guardian deer repellent fertilizer with the U.S. Environmental Protection Agency (EPA). The product may be on the market as early as 2008. GOLD’n GRO Guardian will be registered as a biopesticide for use on ornamental landscape plants and shrubs, lawns, flower gardens, golf courses, non-bearing trees, and vines, and by nursery growers of non-food plants. Field trials in cooperation with the North American Deer Management Network have shown the product effective as both a fertilizer and a repellent, lasting up to three months after being sprayed on plants. The national annual market for deer repellent products is growing rapidly and is estimated to exceed $50 million.
