Desiccation by dehydration is the mode of action for FireHawk Bioherbicide. Death by drought is what Dr Rick Haney said when introduced to FireHawk. Nonanoic Acid is the active ingredient. It is combined with the correct mixture of natural oil and wetting agent with an emulsifier package.

FireHawk is a proprietary bioherbicide containing Nonanoic Acid, a naturally occurring organic acid, as active ingredient. Limonene, a natural oil, is added to soften waxy plant tissues. The formulation is optimized for its aqueous spray application with readily biodegradable emulsifier and wetting agent.

Spray directly onto unwanted weeds, making sure to fully cover the leaves and stems. For best results, apply during warm, dry weather and avoid watering or rain shortly after application.

Yes, FireHawk Bioherbicide is safe to use around animals. We recommend keeping animals away from sprayed areas until the spray material has dried. For spray applications made in grazing areas, we recommend keeping the animals out of areas where you will spray until the treated plants have died. If you spray a poisonous plant with FireHawk the plant is still poisonous after it is dead. The necessary steps to prevent animals from eating dead poisonous plants are needed. Additional toxicological information is provided in the Safety Data Sheet document on the products pages.

No! FireHawk Bioherbicide is not harmful to bees. We have numerous customers who are using FireHawk in their apiary operations.

FireHawk can be sprayed adjacent to bodies of water but not on bodies of water that contain aquatic life. The ingredients in FireHawk are readily biodegradable and rapidly digested by the soil microorganisms and leave behind no harmful residue.

FireHawk Bioherbicide is a contact herbicide. It only affects the soft tissue parts of the plants it touches like green leaves and stems. It does not permeate through woody parts of the plants like bark, branches or a tree trunk. It is not systemic and will not translocate in the plant.

: If you spray your weeds with FireHawk Bioherbicide Ready to Use Spray Mixture, people and pets may enter treated areas after the spray has dried. If you use FireHawk Bioherbicide Concentrate, you have to first prepare a spray mixture by diluting the Concentrate with water. The concentrate needs to be handled with care and avoid getting any of the concentrate in your eyes or on your skin. Wear goggles to protect your eyes, wear a long-sleeved shirt and pants, and also wear gloves to cover your hands. Due to the high concentration of the nonanoic acid and natural oil in the FireHawk Bioherbicide Concentrate, the EPA has classified this product with a ’Danger’ hazard rating that automatically carries a 48-hour reentry period even when sprayed as a diluted spray mixture. For your information, that spray mixture (made from the concentrate) has the same concentration level of ingredients as the Ready To Use Spray Mixture that has an allowed reentry after the spray has tried.

The FireHawk Bioherbicide spray mixture is rain safe in 1 hour.

FireHawk is a proprietary bioherbicide containing Nonanoic Acid, a naturally occurring organic acid, as active ingredient. Limonene, a natural oil, is added to soften waxy plant tissues. The formulation is optimised for its aqueous spray application with readily biodegradable emulsifier and wetting agent. Based on the current US organic certification scheme, our product does not meet its criteria. We are continuously developing our weed control technology and intend to attain organic certification in the future.

The current warehouse is in Utah but will be in numerous retail outlets in the near future.

We have an online store. You can order either the FireHawk concentrate or Ready to Use Spray Mixture (RTU) online. The 55G & 275G containers require a quote for shipping cost which we will gladly provide. You may contact us by email or phone. Info@firehawkbioherbicide.com 712-973-8407

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.

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.
