Garlic Barrier is a very strong liquid garlic extract that mixes with water and is sprayed on farm and garden plants to keep insects off. The garlic used in Garlic Barrier is a very powerful variety which is much more potent than the garlic found in grocery stores (in fact, our lab people here refer to it as "super garlic"). There is a huge list of insects that it works on and you may see them by reviewing our label on this web site (see link to label info at page bottom). One gallon, properly mixed with water, covers 10 to 12 acres of row crops or 5 acres of orchards. It imparts no garlic taste on any crops or plants that are sprayed. The odor of garlic in the air or on the plant disappears in about 30 minutes. It's all natural and listed by OMRI as suitable for organic farm use. It's marvelous for farm, home garden and lawn care use and completely safe around people, pets, animals and fish.
