FireHawk Bioherbicide kills weeds in a similar way to a heavy frost or extreme heat wave. Nonanoic Acid, the active ingredient, quickly breaks down the cells of the plant by degrading the protective film of sprayed plant areas to cause complete dehydration

The formulation is a highly effective desiccant, not a systemic poison, so plants are unable to build resistance.

Our FireHawk Bioherbicide is a natural herbicide designed for agriculture, government, municipalities, the education sector, revegetation programs, parks and gardens as well as small and large homes

When spraying a weed with our FireHawk Bioherbicide spray mixture, nonanoic acid, our active ingredient, penetrates the plant by breaking down the waxy layer that protects the weed's leaf. Contact Biosolutions proprietary delivery technology strongly aides this process. The nonanoic acid enters the plant's cells and destroys its membranes. This causes the weed's moisture to escape. As this process continues, the FireHawk Bioherbicide dehydrates the weed to termination. With no residues remaining in the soil, weeds are unable to build resistance.

As FireHawk Bioherbicde penetrates and desiccates the plant, the plant releases exudates into the soil which feed the soil microbes. A two - year soil study at the University of Missouri has independently confirmed the significant soil health benefits of using Contact Biosolutions Bioherbicides for weed control versus using glyphosate - based herbicides.

Made from natural, non - toxic ingredients means there are no toxins or poisons that can pass into the food chain or the human body

Yes, we have an online store. You can order our FireHawk Bioherbicide products online. The 200L and 1,000L pack sizes require a quote for shipping cost which we are happy to provide, you can contact us by email or phone.

Yes, FireHawk Bioherbicide is non - toxic in spray form and residue free. Domestic animals need to be away while spraying but can re - enter as soon as the product dries off

Toxicological information is provided in the Safety Data Sheet document on the products pages

Under Toxicity Data it states that consuming greater than 20,000mg/kg it would kill 50% of rats. A rat would have to consume 20L of the spray mixture per kg or part thereof, of its own weight to kill it. Therefore a farm animal would have to consume hundreds of litres of spray mixture to reach and exceed this toxicity limit. In a normal spot spraying operation one sprays approximately 10ml per 1sqm of treated area which is way below the toxicity limit of the product. However, Contact Biosolutions recommends keeping people, pets and farm animals out of the area being sprayed, at least until the product has been absorbed in the plants and dried off

No! FireHawk Bioherbicide is non - toxic in spray form and residue free.

FireHawk Bioherbicide Spray Mixture is not detrimental to bees. If bees come in contact with the product in the case of spray drift or wet plants after spraying.

Despite its overall low eco - toxicity and low absolute volume, you should not overspray waterways with FireHawk Bioherbicide spray mixture. Spot spraying weeds in the vicinity of a creek is fine as the spray mixture will enter the weeds and will be used up during the desiccation process. Spray mixture over-sprayed onto the ground is typically absorbed in the soil and neutralized. As the residual product is biodegradable and naturally occurring it will biodegrade within a couple of weeks resulting in a spray site with no FireHawk Bioherbicide residue left

Contact Biosolutions has developed non-toxic FireHawk Bioherbicide products from natural ingredients for several key target markets.

• Around the home and garden
• Landscaping• Public Spaces
• Hobby Farms
• Horticulture
• Vineyards
• Regenerative agriculture
• Crop desiccation
• Invasive and glyphosate-resistant weeds.

Brochures for these market segments are included in the Resources Tab.

Our products have been approved for use in Australia, the USA , New Zealand and Japan

Over many years, environmentally aware gardeners have used vinegar as a basic herbicide. There are many recipes published on the internet which are based on a combination of vinegar, salt and dish washing liquid. If you prepare such a product and spray weeds with it, the initial result looks promising, but it is not really convincing as weeds regrow quickly and hardier weeds are not affected at all.
This is where our product development started and our technology comes into play. Contact Biosolutions' history is in health science and dietary supplement development. We are specialists in making active ingredients bio - available through cutting edge technology and delivery systems
We have applied our delivery technology to acetic acid in our original HomeSafe, LocalSafe and FarmSafe Weed Terminator product range. We continued our research and development and have developed proprietary delivery technology for our nonanoic acid active ingredient and created our FireHawk Bioherbicide that is a superior non - toxic, fast acting , high performing and soil friendly bioherbicide.
Much of the concern over the health and environmental effects of glyphosate - based weedkillers focuses not on the effects of glyphosate alone but on the effects of the adjuvants, both alone and in combination with glyphosate.
How do you know that your adjuvants are safe, both individually and in combination with the active ingredient?
Contact Biosolutions products are based on nonanoic acid and safe adjuvants that are all well - known and occur in nature and are on the USA Environmental Protection Agency (EPA) Inerts Products List
US EPA conducted a thorough review of Contact Biosolutions FireHawk Bioherbicide Concentrate and Ready - To - Use products and compositions, and granted their unconditional regulatory approval for our bioherbicide products.
Europe's TSG Consulting has also conducted independent reviews of Contact Biosolutions raw materials and product compositions and issued their toxicity and eco - toxicity reports, and Safety Data Sheets. These reviews confirm that our products are non - toxic and non - hazardous to the environment at the dilution levels used.

The main benefit of the use of Contact Biosolutions FireHawk Bioherbicide is the low environmental impact of this product. The active ingredient, Nonanoic Acid, is generally regarded as safe, readily biodegradable and leaves no toxic residue. This product provides a safer alternative to toxic synthetic pesticide-based herbicides.

The University of Missouri, a leading research university in the USA, has conducted a 2 year comparative study of the impact of Contact Biosolutions Bioherbicide product and Glyphosate on soil microbiology.Click here to read that report. Please note the product names in the report are the USA product names.

The research confirmed that controlling weeds with Contact BioSolutions FireHawk Bioherbicide is beneficial to soil microbiology and therefore to agriculture.

One of the most damaging organisms to soil health is a fungus known as fusarium. Research laboratory evaluations confirmed that in comparison to glyphosate which caused a dramatic increase of the fusarium Contact Biosolutions Bioherbicide had a dramatic effect on fusarium to the point of almost elimination. Fusarium can contribute significantly to the loss of propagation material.

A most important bacteria known as the Pseudomonas fluorescens had multiplied dramatically. This particular organism is responsible for the creation of root nodules. Root nodules in turn are responsible for collecting nitrogen from the soil and the atmosphere and making it bio-available to the plant.

FireHawk Bioherbicide is a contact herbicide with Nonanoic acid as the active ingredient. Nonanoic acid is a fatty acid that naturally occurs in vegetables and oils like the oil of the pelargonium plant.

FireHawk Bioherbicide spray mixture at a 1:20 dilution rate will kill weeds and grasses that have been directly sprayed. The trunk/bark of young trees will not be affected as it is much hardier. If tree leaves are sprayed on, there might be a small level of browning noticeable, but the tree health will not be affected by the FireHawk Bioherbicide spray mixture. Nonanoic acid will start biodegrading within hours of spraying and will fully biodegrade over a couple of weeks and will not leave any residue in the area.

The potency of FireHawk Bioherbicide product depends on its dilution level. FireHawk Bioherbicide in a fully concentrated form would burn surface roots of young plants. However, at a 1:20 dilution level, it will not harm surface roots of young plants when sprayed on weeds in the surrounding area.

FireHawk Bioherbicide spray mixture is based on Nonanoic Acid and has a slightly acidic pH of 5. Contact Biosolutions advises not to spray the product directly onto waterways. However, as it is being used for weed control through spot spraying and its active ingredient, Nonanoic Acid, will biodegrade over a shorter period of time, there will not be a large enough quantity of the product in the system to have any impact on aquatic life.

Please consult FireHawk Bioherbicide spray mixture SDS before spraying. FireHawk Bioherbicide spray mixture is a non-hazardous product. It contains nonanoic acid as the active ingredient and a minor amount of Limonene, a natural oil derived from lemon peel. However, as it has a pH of 5 it can cause irritations of the eyes and skin if directly sprayed on or through spray drift. Please wear recommended personal protective equipment and wash your hands after use. Details are included in the SDS

FireHawk Bioherbicide spray mixture is non-hazardous and non-toxic. It will be fully absorbed by the plants sprayed within a very short time. It will start biodegrading within hours of the spray and will fully biodegrade over a couple of weeks and will not leave any residue in the area.

Children/Pets can enter the area safely when spray has dried off or after a day of spraying.

The FireHawk Bioherbicide product is rain proof after 1 hour but we advise not to conduct a weed spray if rain is expected within 2 hours. The product works by penetrating the weed through its green parts, which need to be covered in the spray mixture. If rain washes the mixture off soon after application you may not see the full effect of our product and need to re-apply. However, depending on the time of day, weather conditions prior to rain, rain amount and weeds targeted, you may still see optimal results even if rain occurs soon after application.

At this stage, our FireHawk Bioherbicide product has not been certified for organic production. The key reason is that our FireHawk Bioherbicide includes a surfactant which is fully biodegradable but chemically made. The current organic certification scheme does not certify products that include chemically made surfactants.

While we hold patents on organically certifiable herbicides, we focus our business on offering the market a non-toxic, non-residue, high performing and cost effective bioherbicide. Our product has been independently validated by the University of Missouri in a 2 year research study as beneficial to soil microbiology. This is a most important verification of our product’s environmentally friendliness and perfectly positions us as a key player in regenerative agriculture that is all about improving soil health. We are not aware of any organic input certified herbicide which has that soil health validation.

Our FireHawk Bioherbicide has been formulated from natural ingredients, is non-toxic and beneficial to soil health when being applied in a weed spray application.

The FireHawk Bioherbicide Ready to Use product range is available through our Online Store, it is shipped from our warehouse in Melbourne, Victoria.

The FireHawk Bioherbicide Concentrate product range is available from us directly, and through our resellers and distributors Freight is organized through our networks and it depends the location.

FireHawk Bioherbicide is a high-performance, broad spectrum, contact bioherbicide made from natural ingredients. Our proprietary delivery technology significantly enhances the effectiveness of nonanoic acid, the active ingredient. FireHawk Bioherbicide kills weeds by desiccation.

When you spray weeds with FireHawk Bioherbicide, you will see results typically in a couple of hours. Depending on type of weed, climate and dilution the desiccation process can take up to one week.

As our FireHawk Bioherbicide is a contact herbicide, it is recommended to spray the weeds to run off. The green parts of the weeds should be covered with the spray mixture. FireHawk Bioherbicide will kill and control your normal pathway weeds including fleabane, fireweed, milk thistle, thistle, small oxalis, clover, richardia, bindii, flat weed, various creeping weeds, winter grass, summer grass, calthrop, paspalum grass, couch grass and general everyday weeds.

Some woody or perennial weeds and those with deeper roots will require a re-spray. For example, couch grass with its large root system and runners will require a couple of resprays to get fully under control. It is recommended to respray after 2-3 weeks when the plant is in the process of recovering and putting all its energy into this process.

As a broad spectrum, non-selective bioherbicide FireHawk Bioherbicide does affect all plants it comes into contact with. The target weeds only should be sprayed. However, it does not impact larger woody plants, trees and bushes when spray drifts on them. For example, a limited spray drift on grape vines will barely be noticeable - most likely just resulting in only a couple of brown spots on the leaves.

Take care when spraying near seeds and flower heads of actively growing plants so that the desiccation nature of our FireHawk Bioherbicide does not harm the plant.

Control of tougher weeds is possible by increasing the concentration of the FireHawk Bioherbicide in the spray mixture and increasing application rates. Please refer to the label and our Weed Guide for instructions.

Large invasive grass plants, such as pampas grass may require a higher concentrated spray mixture once you have desiccated the seeds. Cut it down low and spray the remaining clump. This is a tough gnarly root to kill. Check and re-spray until dead. Targeting various wild grasses such as Lomandra's, love grass, serrated tussock, and Kikuyu will require spraying the centre until soaked.

Use a stronger mix on tougher weeds like Crofton, varieties of calthrop, Patterson's curse, farmers friend, African burs, stink weed, nettle, penny wart and giant parramatta grass, and Round-up resistant weeds. Nut grass is best to spray in flower.

Weed runners like turkey rhubarb and fleshy madeira vine with tubers, require spray to defoliate. The re-growth will tell you where the tuber is. Spike down the centre of its base and add some mix down the hole. For onion weed in lawns and gardens rip off the head and spray down the centre of its base. For oxalis, spray the foliage and soak the base. For wandering jew, rake it, bin it, then spray with a stronger mix to kill off the runners. You will need to pick out all the bits that hide under roots and rocks, then re-spray and make sure you re-check or it may come back.

Healthy buffalo grass - mow low first and spray it twice.

Targeting woody weeds like bitou bush, blackberry, juvenile privet, lantana and camphor laurel

Spray plants to kill seeds and buds. Cut it down, scrape some bark off the root or stem to the cambion layer, and spray that. Come back and spray and soak any re-growth.

If you can't cut it down, spray when it is flowering. Knock out all the flowers and buds. The weed will go into shock and will become dormant. Spike around the root base and scrape to the Cambion layer and spray.

Follow up with FireHawk Bioherbicide spray to knock out the re-growth and kill the seeds. You may need to repeat a few times until you gain full control of these really tough weeds.

Once weeds are controlled, dilute the mix to the lower maintenance levels.

Please Refer to our Weed Guide

Best way we have found to beat lantana is to use a mulcher slasher like the INO mulcher then when any young shoots sprout you can spray them with FireHawk Bioherbicide.

You must saturate all leaves with this product for it to be effective. Reducing the volume of leaf also makes the process more economical for you.

Please Refer to our Weed Guide

Mother-of-millions - Bryophyllum delagoense is a hardy succulent that would need to be sprayed with a strong mix rate of FireHawk Bioherbicide: Water of 1:10. We would also cut the plant down and spray new growth for a better economic outcome for you. Ochna has over 80 species, but the most common in your area has a solid firm bark. Once again, repeat the process above and also scrape back the bark on the trunk to expose around 100 to 200mm, what is called the cambium layer. This is a thin green layer under the bark, spray that exposed area at the same time. We have had also success with this method on plants such as black berry and other bramble types.

Do you have a product that is effective on aggressive woody weeds like lantana? Best way we have found to beat lantana is to use a mulcher slasher like the INO mulcher then when any young shoots sprout you can spray them with FireHawk Bioherbicide.

You must saturate all leaves with this product for it to be effective. Reducing the volume of leaf also makes the process more economical for you.

When you spray weeds with FireHawk Bioherbicide, you will see results typically in a couple of hours. Depending on type of weed, climate and dilution the desiccation process can take up to one week.

As our FireHawk Bioherbicide is a contact herbicide, it is recommended to spray the weeds to run off. The green parts of the weeds should be covered with the spray mixture. FireHawk Bioherbicide will kill and control your normal pathway weeds including fleabane, fireweed, milk thistle, thistle, small oxalis, clover, richardia, bindii, flat weed, various creeping weeds, winter grass, summer grass, calthrop, paspalum grass, couch grass and general everyday weeds.

Some woody or perennial weeds and those with deeper roots will require a re-spray. For example, couch grass with its large root system and runners will require a couple of resprays to get fully under control. It is recommended to respray after 2-3 weeks when the plant is in the process of recovering and putting all its energy into this process.

As a broad spectrum, non-selective bioherbicide FireHawk Bioherbicide does affect all plants it comes into contact with. The target weeds only should be sprayed. However, it does not impact larger woody plants, trees and bushes when spray drifts on them. For example, a limited spray drift on grape vines will barely be noticeable - most likely just resulting in only a couple of brown spots on the leaves.

Take care when spraying near seeds and flower heads of actively growing plants so that the desiccation nature of our FireHawk Bioherbicide does not harm the plant.

Control of tougher weeds is possible by increasing the concentration of the FireHawk Bioherbicide in the spray mixture and increasing application rates. Please refer to the label and our Weed Guide for instructions.

Large invasive grass plants, such as pampas grass may require a higher concentrated spray mixture once you have desiccated the seeds. Cut it down low and spray the remaining clump. This is a tough gnarly root to kill. Check and re-spray until dead. Targeting various wild grasses such as Lomandra's, love grass, serrated tussock, and Kikuyu will require spraying the centre until soaked.

Use a stronger mix on tougher weeds like Crofton, varieties of calthrop, Patterson's curse, farmers friend, African burs, stink weed, nettle, penny wart and giant parramatta grass, and Round-up resistant weeds. Nut grass is best to spray in flower.

Weed runners like turkey rhubarb and fleshy madeira vine with tubers, require spray to defoliate. The re-growth will tell you where the tuber is. Spike down the centre of its base and add some mix down the hole. For onion weed in lawns and gardens rip off the head and spray down the centre of its base. For oxalis, spray the foliage and soak the base. For wandering jew, rake it, bin it, then spray with a stronger mix to kill off the runners. You will need to pick out all the bits that hide under roots and rocks, then re-spray and make sure you re-check or it may come back.

Healthy buffalo grass - mow low first and spray it twice.

Targeting woody weeds like bitou bush, blackberry, juvenile privet, lantana and camphor laurel

Spray plants to kill seeds and buds. Cut it down, scrape some bark off the root or stem to the cambion layer, and spray that. Come back and spray and soak any re-growth.

If you can't cut it down, spray when it is flowering. Knock out all the flowers and buds. The weed will go into shock and will become dormant. Spike around the root base and scrape to the Cambion layer and spray.

Follow up with FireHawk Bioherbicide spray to knock out the re-growth and kill the seeds. You may need to repeat a few times until you gain full control of these really tough weeds.

Once weeds are controlled, dilute the mix to the lower maintenance levels.

Best way we have found to beat lantana is to use a mulcher slasher like the INO mulcher then when any young shoots sprout you can spray them with FireHawk Bioherbicide.

You must saturate all leaves with this product for it to be effective. Reducing the volume of leaf also makes the process more economical for you.

Mother-of-millions - Bryophyllum delagoense is a hardy succulent that would need to be sprayed with a strong mix rate of FireHawk Bioherbicide: Water of 1:10. We would also cut the plant down and spray new growth for a better economic outcome for you. Ochna has over 80 species, but the most common in your area has a solid firm bark. Once again, repeat the process above and also scrape back the bark on the trunk to expose around 100 to 200mm, what is called the cambium layer. This is a thin green layer under the bark, spray that exposed area at the same time. We have had also success with this method on plants such as black berry and other bramble types.
