    Corvus herbicide provides outstanding control of a broad spectrum of broadleaf and grass weeds in corn.

    •

    Delivers three levels of control to fight weeds: rapid burndown for emerged weeds, residual control to prevent newly emerging weeds and reactivation with rain for prolonged weed control

    •

    Offers flexibility in application timing as it can be applied pre-emerge, pre-plant incorporated, or early post-emerge (up to 2 leaf)

    •

    Excellent resistance management tool and tank-mix partner with Roundup® brands

      Will provide improved (over lower rates) control of tall waterhemp, large crabgrass and green foxtail

      Plant corn at least 4 cm deep. Failure to close the seed furrow may allow herbicide spray to directly contact the seed which can cause injury.
      Corvus treatments are most effective in controlling weeds when adequate rainfall is received within 14 days after application
      For ground application:
      For best results use flat fan nozzles or comparable nozzles to achieve uniform spray distribution. Do not apply with hollow cone nozzles or with other application equipment which does not provide uniform coverage.
      Apply Corvus in a minimum of 150 L/ha (15 gal./ac.) of total spray volume. Sprayable fluid fertilizer (nitrogen solution) may replace all or part of the water as a carrier for pre-plant (surface or incorporated) and pre-emergence applications.
      Accurately calibrate the sprayer prior to mixing the herbicide treatments
      Do not use sprayable fluid fertilizer (nitrogen solution) as the carrier for early post emergence applications as the nitrogen solution can typically cause corn injury such as tissue burn (necrosis)
      Do not use any adjuvants with Corvus when applied to emerged field corn
      Do not apply Corvus to field corn grown on loamy sands or sands and/or soils with less than 2% O.M.Apply Corvus alone or in tank mixtures, by ground equipment only. Do not apply with aerial application equipment.
      Refer to the nozzle manufacturer’s recommendations for proper nozzle, pressure setting and sprayer speed for optimum product performance and minimal spray drift
      Agitate thoroughly before and during application with either bypass or mechanical agitation
      Pre-plant/pre emergence burndown spray additives:
      For control of emerged weeds prior to corn emergence, Corvus may be used in conjunction with an adjuvant: COC or MSO applied at 1% volume/volume or a non-ionic surfactant (NIS), such as Agral® 90 or Agsurf®, applied at 0.25% volume/volume
      Early post emergence to corn:
      If applying early post emergence to corn, do not use any adjuvants with Corvus
      Refer to the product label for any post-emergent applications

      		45 days of harvesting corn forage
      		12 hours
      		Do not graze or feed the immature corn to livestock prior to 45 days of Corvus application

      Ground application only.
      Corvus herbicide can be applied broadcast in a minimum of 150 L/ha (15 gal./ac.) of total spray volume. Sprayable fluid fertilizer (nitrogen solution) may replace all or part of the water as a carrier for pre-plant (surface or incorporated) and pre-emergence applications.

      2 hours Avoid application of Corvus when heavy rain is forecast

      For a list of permissible tank-mix partners and mixing order, please refer to the product label.

    title-additional-guidelines

      Corn (field, seed): Immediate plant back.
      Wheat (winter): 4 months after a spring application of Corvus.
      Barley (spring), Corn (field, seed), Soybeans, Wheat (spring): 10 months

      Please note that Corvus is both a Group 2 and a Group 27 herbicide. Any weed population may contain or develop plants naturally resistant to Group 2 and/or Group 27 herbicides.
