Fierce

Herbicide

Fierce® herbicide provides extended grass and broadleaf weed control for pulses, soybeans, and spring wheat crops with two active ingredients (Group 14 and 15) to help manage resistance weeds.

Technical Information

Active ingredients: Group 14 (flumioxazin), Group 15 (pyroxasulfone) 
Treatment rate: One case treats 128 acres at 85 g/ac. (32 ac./jug)
Application timing: Fall apply as late as possible but prior to freeze up for any registered crop, pre-plant or pre-emergent for chickpeas, field peas, and soybeans, should be applied a minimum of  7 days prior to seeding field corn and spring wheat, apply up to 3 days after seeding chickpeas, field peas and soybeans
Tank-mix order: Fierce, BlackHawk or GoldWing (if used), glyphosate
Notes: Seeding after application requires the use of minimum to zero till drills, requires moisture to activate in the soil and can provide up to 8 weeks extended control

Registered Crops

  • Chickpeas
  • Field corn
  • Field peas
  • Lentils (fall application prior to large green and small red varieties)
  • Soybeans
  • Spring wheat (not including durum)

Weeds Controlled

Chickweed Dandelion
Green foxtail Green and Redroot pigweed
(including Group 2- and Group 5- resistant biotypes)
Kochia
(Group 2-, 4- and glyphosate-resistant biotypes)
Lamb’s quarters
(including Group 2- and triazine-resistant biotypes)
Wild buckwheat Wild mustard
Volunteer canola (suppression)  

Benefits

  • BETTER PERFORMANCE than other leading residual herbicides on tough broadleaf weeds
  • GRASSY WEED MANAGEMENT for cleaner fields with a different mode of action
  • LONGER CONTROL with residual activity that lasts up to 8 weeks
  • TWO ACTIVE INGREDIENTS (proven Group 14 and new Group 15)  for management of Group 1-, 2-, 4-, 5- and glyphosate-resistant weeds 
  • Convenient application eliminates the need for granular broadcast herbicide products
  • Tank-mixable with most burndown and pre-emergent herbicides (i.e. glyphosate, BlackHawk and GoldWing)

Performance Tips

  • Emerged weeds – use with a burndown herbicide partner like glyphosate, BlackHawk and/or GoldWing
  • Flushing weeds – residual activity for newly emerging weeds
  • Emerged crop – Fierce alone can be used up to 3 days post seeding of soybeans
  • Refer to label or crop guide for rates and use patterns
  • DO NOT incorporate after application or prior to seeding
  • Pre-seeding applications require the use of minimum disturbance seeding systems
  • Non-ionic surfactant required if glyphosate is not being tank mixed
  • Leave a small check-strip in the field to show performance

Weed Control Challenge

Remember when glyphosate or other non-residual herbicides were all it took to control your wild oats and most broadleaf weeds? Unfortunately, herbicide-resistant weeds mean that Groups 1, 2, 4, 5 and 9 can’t handle the problems alone anymore. Maximizing soybean and wheat yields depend on residual control of tough grass and broadleaf weeds.

Nufarm Solution

Fierce herbicide delivers broad-spectrum, extended residual weed control. Pyroxasulfone is registered for suppression of wild oats and control of various foxtail and brome species at a rate consistent with the upper registered range of Fierce. This provides another option to reduce the effect of Group 1 and 2 resistant grassy weeds, and other broadleaf weeds that impact yield and harvest management. Fierce controls resistant weeds before they become a problem.
