JH Biotech Weed Zap Herbicide

Yes, Weed Zap is non-selective, meaning it will damage or kill any green plant tissue it touches. You should use a shield or careful aim when spraying near flowers, shrubs, or vegetable crops to avoid accidental contact.

This product requires a 5% dilution ratio. You should mix 5 gallons of concentrate with 95 gallons of water, or scale that down proportionally for smaller sprayers—for example, roughly 6.4 ounces of concentrate per gallon of water.

Yes, because it is OMRI-certified for organic production, it is suitable for use in vegetable gardens. Just be careful to apply it only to the weeds you want to remove, as it will affect any vegetable plant it contacts.

Weed Zap is most effective on small, actively growing weeds that are 6 inches tall or less. For larger, more established weeds, you may find that it only burns back the top growth rather than killing the root system entirely.

You can expect to see visible results within 12 hours of application. The essential oils work quickly to desiccate the plant tissue, causing the weeds to wilt and turn brown.
