Technical Information

Active ingredient:  Group 14 (flumioxazin)
Rainfast:  Rain required for activation
Treatment area:  60-90 mL/acre, one case treats 106-160 acres (consult label for more information)
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-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 activate in the soil.

  • EARLY SEASON CONTROL helps eliminate broadleaf weed pressure in pulses, wheat and soybeans during critical weed periods 
  • EXTENDED SOIL ACTIVITY takes out multiple flushes of tough weeds for up to 8 weeks
  • RESISTANCE MANAGEMENT TOOL that helps manage weeds on the Valtera EZ product label that are resistant to Group 2-, 4- and glyphosate-resistant herbicides
  • RE-CROPPING FLEXIBILITY – most crops not listed on the product label can be seeded 12 months after application
  • Apply in fall or spring (check product label for specific crop registrations)
  • No hassle application that doesn’t include the handling and incorporation of bulky granular herbicide products
  • Extended early season control for extra in-crop herbicide flexibility that helps to improve the efficacy of in-crop herbicide applications by targeting fewer, smaller weeds
  • Yield potential is increased through early elimination of weed competition

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. Application flexibility – Valtera EZ alone can be used up to 3 days post-seeding, but prior to emergence of soybeans, chickpeas and field peas
  4. DO NOT incorporate after application or prior to seeding
