Overview
FireHawk Bioherbicide Super Concentrate is a fast-acting, non-selective contact herbicide made with nonanoic acid, a fatty acid. Mixed with water, it burns down actively growing broadleaf weeds, grasses, mosses and other unwanted green vegetation, with visible effects on most weeds within hours.
Where to use it
- Driveways, walkways, patios, gravel and mulch beds
- Fence lines, edging and along foundations
- Landscaped beds and around trees and shrubs, sprayed only on the weeds
- Bed preparation before planting: treated areas may be reseeded or planted once the weeds are controlled
How it works
FireHawk works on contact and is not translocated: it burns only the green plant parts the spray covers, so coat the whole weed. It does not damage mature, non-green, woody parts of plants and leaves no residual weed control in the soil. Young weeds that are actively growing respond best; repeat treatments are needed for new weeds coming up from seed or regrowth.
Mixing
Shake well. Fill the sprayer 3/4 with water, add the product, then top off with water and mix. The label rate table calls for 2.0 fl oz per gallon of spray for young weeds, 2.6 fl oz for establishing control and mature weeds, 4.1 fl oz for mature perennial weeds and 6.1 fl oz for woody weeds and maximum burndown. At the lowest rate, 16 fl oz makes up to 6.25 gallons of spray, 32 fl oz up to 12.5 gallons, 1 gallon up to 50 gallons and 1.33 gallons up to 67 gallons. A cone nozzle gives the most even coverage.
Important
- Non-selective: it damages any green plant it touches, including lawn grass. Shield plants you want to keep from drift with cardboard or plastic.
- Do not apply if rain is expected within 2 hours, or to weeds wet from dew, rain or irrigation.
- Keep people and pets off treated areas until the spray has dried.
- Wear the protective equipment listed on the label when mixing the concentrate (gloves and eye protection).
- Always read and follow the label directions. Keep out of reach of children.
