Valtera EZ


Valtera™ EZ is a new liquid pre-emergent soil active herbicide that offers early season broadleaf weed control in pulses, soybeans, wheat and field corn. It knocks out troublesome weeds like kochia, chickweed, lamb's quarters, pigweed and many more.

Technical Information

Active ingredient:  Group 14 (flumioxazin)
Rainfast:  Rain required for activation
Treatment area:  One case (2 x 4.8 L) treats 160 acres at 60 ml/ac. rate
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. Pre-plant or pre-emergent for soybeans, field peas and chickpeas. Should be applied a minimum of 7 days prior to seeding field corn, wheat and lentils. Apply up to 3 days after seeding soybeans, chickpeas and field peas. Must be applied 30 days prior to seeding durum wheat.
Tank-mix order:  Valtera EZ, BlackHawk or GoldWing (if used), glyphosate
Notes:  Seeding after application requires the use of minimum to zero-tillage drills. Valtera EZ requires moisture to activiate in the soil.

Registered crops

  • Chickpeas
  • Field corn
  • Field peas
  • Lentils (large green and small red varieties)
  • Soybeans
  • Wheat

Weeds controlled

  • Annual sow-thistle
  • Canada fleabane*
  • Chickweed
  • Cleavers (suppression)
  • Common ragweed
  • Dandelion (seedling)
  • Green foxtail (suppression)
  • Green pigweed
  • Kochia (including Group 2-, 4- and glyphosate-resistant biotypes)
  • Lamb’s-quarters
  • Nightshade
  • Palmer amaranth*
  • Redroot pigweed
  • Russian thistle (suppression)
  • Volunteer canola – all biotypes (suppression)
  • Waterhemp (including Group 2-, 5- and glyphosate-resistant biotypes)*
  • Wild buckwheat (suppression)

*Farmers in Southern Manitoba should watch for these weeds moving northward from the US.


  • Early season control eliminates broadleaf weed pressure early on in pulses, wheat and soybeans
  • Extended residual control (up to 8 weeks) on tough weeds
  • New liquid formulation requires no surfactants and is easier to handle
  • Resistance management tool helps to manage glyphosate-resistant weeds
  • Apply in fall or spring (check label for specific crop registrations)
  • 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
  • More re-cropping flexibility the following year
  • Tank-mixable with most burndown and pre-emergent herbicides (ie. glyphosate, BlackHawk and GoldWing)

Performance tips

  1. Emerged weeds – use with a burndown herbicide partner like glyphosate and BlackHawk or GoldWing
  2. Flushing weeds – residual activity for newly emerging weeds
  3. Emerged crop – Valtera EZ alone can be used up to 3 days post planting but prior to emergence of soybeans, chickpeas and field peas
  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-plant applications require the use of minimum disturbance seeding systems
  7. Leave a small checkstrip in the field to show performance
