Wilt Pruf is generally used as an adjuvant on evergreens and woody plants. I would advise you against using it in a recipe that will be sprayed on edible plants since its specific effects are unknown. You might try something like Animal Stopper. It is not applied directly to the plants but is spread around the garden as a repellant. Many times the homemade recipes can be more expensive than buying a commercial product once all the infividual components are purchased.
