Valtera™ is a pre-emergent residual herbicide that offers up to 8 weeks of early season broadleaf weed control in pulses, soybeans and spring wheat.


  • Active ingredient:  Group 14 (flumioxazin)
  • Rainfast:  Rain is required for activation
  • Treatment rate:  56 g/ac. – One case treats 160 acres
  • Application:  Tank mix with glyphosate and/or BlackHawk/GoldWing for enhanced control of emerged weeds
  • Application timing:  Fall apply as late as possible but prior to freeze up for any registered crop, apply up to 3 days after seeding soybeans and field peas, should be applied 7 days prior to seeding spring wheat and field corn
  • Tank-mix order:  Valtera, glyphosate, BlackHawk or GoldWing (if used)
  • Notes:  Apply Valtera up to 3 days after seeding soybeans and field peas. Seeding after application requires the use of minimum to zero till drills. Valtera should be applied a minimum of 7 days before seeding spring wheat.

Registered crops

  • Chickpeas
  • Field peas
  • Lentils (fall application prior to large green and small red lentils)
  • Soybeans
  • Spring wheat (not including durum)(Apply 7 days prior to seeding)

Weeds controlled

  • Chickweed
  • Dandelion (seedling)
  • Green foxtail (suppression)
  • Kochia
  • Lamb’s-quarters
  • Pigweeds
  • Volunteer canola – all biotypes (suppression)

Weed Control Challenge

Early season competition from tough-to-control weeds

Early season weeds put serious pressure on young pulse and soybean plants, competing with the vulnerable crop for nutrients, moisture and sunlight. And when weeds include tough-to-control pigweed, volunteer canola, lamb’s-quarters, dandelion and nightshade, pulses and soybeans have to fight that much harder to get off to a strong start.

Nufarm Solution

Residual weed control for stronger yields

Valtera™ herbicide knocks out troublesome broadleaf weeds with long-term (up to 8 weeks) residual control in pulses, and both Roundup Ready and conventional soybeans. Using Valtera (pre-plant or pre-emergent) with a glyphosate burndown provides residual control, boosts yields, and provides flexibility to seed wheat if cropping plans change.


  • Early season control eliminates early season broadleaf weed pressure in lentils, field peas, chickpeas, spring wheat and soybeans
  • Extended control with powerful residual activity that provides longer lasting control of tough weeds (up to 8 weeks)
  • Resistance management tool that also controls glyphosate-resistant weeds


  • Apply in fall or spring (check label for specific crop registrations)
  • No hassle application that doesn’t include the handling and incorporation of bulky granulars
  • Extended early season control for extra in-crop herbicide flexibility and to improve the efficacy of in-crop herbicide applications by having to target fewer, smaller weeds
  • Yield potential is increased through early elimination of weed competition, especially in soybeans
  • More re-cropping flexibility the following year
  • Tank mixable with most burndown and pre-emergent herbicides (ie. glyphosate, GoldWing and BlackHawk)

Performance Tips

  1. Emerged weeds – use with glyphosate
  2. Flushing weeds – residual activity for newly emerging weeds
  3. Emerged crop – Valtera alone can be used up to 3 days post seeding but prior to emergence of registered crops other than wheat
  4. Refer to label or crop guide for rates and use patterns
  5. DO NOT incorporate after application or anytime prior to seeding
  6. Pre-seed applications require the use of minimum disturbance seeding systems
  7. Non-ionic surfactant required if glyphosate is not being tank mixed
