Weed Control Challenge

Growing range of weed control challenges in canola
Glyphosate has been used for years for effective burndown. But with the widespread adoption of glyphosate-tolerant crops like canola and the spread of glyphosate- and Group 2-resistant weeds like kochia and cleavers, growers are now faced with more weed control challenges than ever. Products with a single active ingredient have too narrow a spectrum to control the growing range of weeds.

Nufarm Solution

Complete weed control that’s safe on canola
CONQUER® delivers faster, more complete weed control in a canola pre-seed burndown than glyphosate alone. CONQUER has two active ingredients with two separate modes of action, and when mixed with glyphosate, weeds face a triple action threat especially kochia, cleavers, narrow-leaved hawk’s-beard, volunteer canola, plus Group 9- (glyphosate) and Group 2- tolerant volunteers.


  • Volunteer canola control.
  • Fast. Exceptionally fast burndown compared to bromoxynil alone
  • Excellent control. Superior weed control including all Group 2 and 9- resistant biotypes of volunteer canola, kochia and cleavers. Contains a Group 14 active thats new for Canada, and a group 4 active ingredient that work together to control tough-to-kill weeds.
  • Non residual. No soil residual activity eliminates any risk to emerging canola crop


  • No safer product available for use before seeding canola
  • Controls the most troublesome weeds including resistant volunteer canola
  • Protects long-term viability of agronomic tools such as glyphosate and glyphosate-tolerant traits
  • No surfactant required when used with glyphosate
  • Active Ingredient: 
    • Group 14 (carfentrazone)
    • Group 6 (bromoxynil)
  • Rainfast: 
    • 6 hours
  • Treatment area: 
    • One case treats 80 acres
  • Tank-mix order:
    • carfentrazone
    • bromoxynil
    • glyphosate
  • Notes: 
    • Canola can be seeded immediately after application

Performance Tips

CONQUER is a contact herbicide and must be applied directly on growing weeds for effective results.

  1. Droplet size – use a combination of nozzle type and sprayer speed to achieve a fine to medium droplet size. Adjust sprayer speed to optimize weed coverage.
  2. Water volume – use 10 gal./ac. water volume for adequate coverage on weeds.
