Black Jack 21 percent Vinegar Weed Killer

This organic vinegar based weed killer has a base of 21 percent acidity vinegar, which is extremely strong and effective at killing plants.

The 1 gallon organic weed killer bottle also contains Yucca Extract, Olive Oil, Garlic Oil, Citrus Oil and Molasses. Those ingredients work as sticking, wetting and emulsifying agents, which makes the vinegar work more effectively.

You pour this product into a spray bottle to apply it and spray it directly onto the plant. If you don't have an empty, cleaned out plastic spray bottle at home, you can get one from most grocery stores or hardware stores.
