BioSafe Weed & Grass Killer is a non-selective herbicide that works on contact when applied as a foliar application. This OMRI Listed product works on perennial and annual broadleaf and grass weeds in two ways: as a control and for burndown suppression. Plants that produce spores, such as liverworts and mosses, will also be controlled. For best results, use on weeds before they mature and cover plant leaves thoroughly and uniformly with spray. Take care to avoid contacting wanted plants. Within 1-2 hours of application you will begin to see it working; the plant's foliage will turn from green to brown or black. This soap product penetrates the cell walls of the plant to disrupt their normal functioning and cause death; the browning of the leaves is due to this necrotic plant tissue. This product does not move through the soil or between plants and leaves no harmful residue.

Spraying Instructions: Thoroughly saturate foliage and stems of undesirable weeds. Stop sprays once runoff from weeds occurs. During application, some foaming may occur; however, weed control is unaffected if the foam is deposited on the plant surface and is not blown away as drift.
Usage Notes: Do not apply this product through any irrigation system. Spray equipment options include hand-held and hose-end sprayers. Spray nozzles that produce a uniform spray will give maximum coverage of the leaves and improved weed control. Do not apply to weeds when wet from dew, rain or watering. Avoid watering within 2 hours after application. Do not apply if rainfall is expected within 2 hours.
- A 10-13% volume to volume (V/V) dilution (13-16 fl. oz. per gallon of water) is recommended for most weed control situations.
- The larger the plants, the higher the application rates needed to ensure maximum herbicidal activity. Also, the higher the concentration, the quicker the plants wilt and turn brown.
Larger weeds, perennial weeds and some grasses may require several applications for complete control.
- See "Application Rates" section on the Product Label for more complete information.
Storage: Store in original container in a cool, well-vented area away from direct sunlight. Do not allow product to become overheated in storage.
