Description

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.

Instructions

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.


Application Rate:

  • 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. This may cause increased degradation of the product, which will decrease product effectiveness. In case of spill, flood area with large quantities of water. Do not store in a manner where cross-contamination with other pesticides or fertilizers could occur.

Technical

Warning & Toxicities: Causes substantial, but temporary, eye irritation. Do not get in eyes or on clothing. Wear goggles. Harmful if inhaled. Avoid breathing spray mist. Causes moderate skin irritation. Avoid contact with skin or on clothing. Wash thoroughly with soap and water after handling and before eating, drinking, chewing gun or using tobacco. Remove and wash contaminated clothing before reuse.

Environmental Hazards: For terrestrial uses only. This pesticide is toxic to fish and aquatic invertebrates. To protect the environment, do not allow pesticide to enter or run off into storm drains, drainage ditches, gutters or surface waters. Applying this product in calm weather when rain is not predicted for the next 24 hours will help ensure that wind or rain does not blow or wash pesticide off the treatment area. Rinsing application equipment over the treated area will help avoid run off to water bodies or drainage systems. This product is toxic to bees exposed to direct treatment or residues on blooming crops or weeds. Do not apply this product if bees are visiting the treatment area.

Active Ingredients/Guaranteed Analysis:

Ammonium Nonanoate……………………………………….40.00%
Other Ingredients……………………………………………..60.00%
Total……………………………………………………………100.00%

Weed and Grass Killer
Feb 8, 2024  |  By Trudy
BioSafe's Weed and Grass Killer works within 24 hours. Spray on small weeds and they will dry up and fade away. This product is the answer to not using poisons on the soil.


Bamboo
Jun 3, 2023  |  By Janice
Arbico is a first class company. The customer service is helpful and orders are fulfilled immediately. I learned of the company from a landscape gardener who uses Arbico organic products exclusively. I've used Biosafe Weed and Grass killer for 2 seasons. My main target is a bamboo-like plant with big heart shaped leaves and hollow stems that grows rampantly out of my neighbor's yard. Biosafe, applied to the leaves, takes care of it within hours. Unfortunately, frequent new shoots require reapplication. After a large stand of bamboo was dug out of my yard, including soil, there was an errant stem left. Biosafe to the rescue. Haven't seen it return (yet). Great product. Great company!


Rapid results
Jul 15, 2022  |  By Warren May
Easy to follow instructions and next day visible effects of vegetation dying. Most vegetation completely dead and dried up within a week. Definitely ranks with the top herbicides I've used in the past and without paraquat.


Very effective
May 2, 2022  |  By Bill Jones
This 1 gallon concentrate will make 7 gallons of liquid to spray small grass shoots. This calculates to about $12/gal. including freight & taxes. No odor while spraying. Do not use with rain forecast in 24 hours. It washes off.


Weed Eliminated
May 21, 2021  |  By Joseph S Ruszczyk
Products worked great. As advertised, weeds began to wilt in less then an hour.

Great price, Great product, Great condition on delivery. I've ordered from you before, and will continue buying from your company.


Works well and safer
Aug 17, 2020  |  By terry wagner
This product is OMRI certified and labeled with WARNING, which is one of the least harmful of designations. It works well.


Best Weed Killer
Aug 2, 2020  |  By Lucille A Jaillet
Found Arbico over a year ago and tried a few of their products. This is one of the best weed killers that I have found. Arbico has great products that work!


Roots remain alive
Jun 29, 2020  |  By John Allyn Caird
The active ingredient, ammonium nonanoate, appears to kill green leafy weeds and grass rapidly above ground, but green shoots also come back a couple of days later, suggesting that the roots of the weeds and grass are still alive underground. Perhaps multiple applications of the product will be more effective.


Works better than clove oil-type sprays
May 11, 2020  |  By Darcy Elizabeth Hitchcock
Arizona weeds are tougher than most so I haven't had much luck with Weed Zapp and similar formulations. But this product has worked well for me, at 1 cup per gallon (less than the recommended concentration) on warm, sunny days. It's taken care of slick grasses as well as broad-leafed weeds. And you can see the results by the end of the day. It doesn't smell as nice as the spice oils but according to the EPA, the half-life is less than 1 day. Just don't use it near bodies of water.


BioSafe
Apr 16, 2020  |  By Colleen Mensel
I am looking for alternative weed control and read about BioSafe. I used it recently with about a 70% success rate. I used the dilution suggested and applied giving full coverage. The same type of weeds and grass had some die off, but not all. I will try a second coat to see if that works, but was expecting a better outcome.
