OMRI Listed for certified organic use. Garlic Barrier AG+ is made from Garlic Juice, Citric Acid and Potassium Sorbate.
Garlic Barrier AG+ can be used in farm, home gardens, for lawn care, around pond edges; however, it is recommended for use in large-scale application. For small-scale applications, use Garlic Barrier. It is safe for use around people, pets, animals and fish. Garlic Barrier AG+ is made from a strong liquid garlic concentrate that has more oil, so it does not have to be mixed with a "spreader-sticker" like the gallon size. When diluted with water and sprayed on garden plants or ornamentals, it will keep insects off.
Just spray it on your plants about once a week. The garlic odor diminishes in about 30 minutes as the plants absorb it, so people are not bothered. Garlic Barrier AG+ travels through the plant systemically, protecting roots, stems, leaves, flowers and fruit. It does not change the taste or smell for humans or livestock, but insects can't stand the natural sulfurs absorbed from the garlic. Insects that do come looking for a meal or a place to lay their eggs are repelled for 1-2 weeks, depending on the insect and conditions.
Garlic Barrier AG+ can also kill adult insects on contact. The citric acid damages many insects' outer coating (cuticle) and the garlic oil suffocates them by clogging their breathing holes (spiracles). Saturate all plants including grass, vegetables and trees for best results limiting pest populations.

For preventative use, apply every 7–14 days or after significant rainfall. Increase frequency during periods of high pest pressure or rapid plant growth.
