BlackHawk

Herbicide

BlackHawk® herbicide is a strong pre-seed burndown solution for battling tough weeds like Group 2- and glyphosate-resistant kochia, cleavers, and volunteer canola in cereals and soybeans.

Technical Information

Active ingredients: Group 14 (pyraflufen-ethyl), Group 4 (2,4-D ester)
Rainfast: 1 hour
Treatment rates: One case treats 60 acres at 300 mL/ac., one drum treats 320 acres at 300 mL/ac. 
Tank-mix order: BlackHawk, glyphosate
Notes: Fall applications can be made until freeze up with no cropping restrictions the following season. For best results make applications to actively growing weeds. Like other herbicides, best results will be achieved with applications on warm fall days 2-3 days after and prior to frost events. For best results, use higher water volumes for good coverage and contact activity.

Weeds Controlled with a Glyphosate Tank-Mix

Canada thistle Narrow-leaved hawk’s-beard (including Group 2 resistant biotypes)
Cleavers (including glyphosate-resistant biotypes) Pigweed (redroot and Russian)
Cocklebur Prickly lettuce
Cow cockle (suppression) Russian thistle
Dandelion (spring seeding and season-long suppression) Shepherd’s-purse
Flixweed Sow thistle
Kochia (including Group 2, 4 and glyphosate-resistant biotypes) Stinkweed
Lamb’s-quarters (including Group 2 and 5 resistant biotypes) Sweet clover
Mustards (except dog and tansy) Volunteer canola (including all herbicide-resistant biotypes)
Narrow-leaved hawk’s-beard (including Group 2 resistant biotypes) Wild buckwheat (suppression)*
Night-flowering catchfly Wild radish

*For optimum control of wild buckwheat, use a rate of 445 mL/ac.

Weed Control Challenge

Glyphosate alone used to provide an effective burndown option in cereal crops. But the widespread adoption of glyphosate-tolerant canola, and the alarming spread of glyphosate and Group 2-resistant kochia has dramatically reduced the effectiveness of glyphosate-only control programs.

Nufarm Solution

BlackHawk contains a Group 14 herbicide (pyraflufen-ethyl) in a pre-formulation with 2,4-D ester. It delivers faster, more complete weed control in a cereal pre‑seed burndown than glyphosate and Group 2 herbicides. With two active ingredients and two modes of action, BlackHawk is an innovative burndown solution that doubles as an effective tool for resistance management.

Benefits

  • PROVEN RESISTANCE MANAGEMENT with two non-Group 2 modes of action to target broadleaved weed species
  • FASTER CONTROL through systemic and contact activity
  • BETTER PERFORMANCE compared to glyphosate alone for pre-seed burndown
  • Makes in-crop weed control easier and more effective by having only new, small weeds present at time of application
  • Provides broad-spectrum weed control, including excellent control of narrow-leaved hawk’s-beard in the fall and at the 1-2 leaf in spring
  • No surfactant needed when applied with glyphosate
