Stewardship and Best Practices

Please read the information below and complete the form to acknowledge your agreement with the Stewardship and Best Practices program.

Corteva Agriscience™, Agriculture, Division of DowDuPont, range and pasture products are effective tools in managing weeds and brush in permanent pasture and grazed rangeland. Understanding precautions, restrictions and how to steward range and pasture products properly is important to ensure satisfactory results and to protect desirable species and the environment.

APPLICATION TIMING

Herbicide application should be made after the majority of the target weed populations have emerged and are actively growing.

  • The ideal timing for application will generally be in June through mid-July with the exception of Canada thistle which enters
    its ideal timing in mid- to late July when the majority of plants have emerged.
  • Timing varies from season to season due to environmental conditions that influence growth and plant staging.
  • When targeting shrubs such as buckbrush or wolf willow, they must be fully leafed out prior to an application.

HAY, SOIL AND MANURE MANAGEMENT

  • Soil from treated areas should never be moved to areas where sensitive plants may be planted within five years.
  • Manure from livestock consuming treated grass should never be used for compost or around susceptible plants.
  • Clippings from grass which have been treated with Corteva Agriscience range and pasture herbicides should never be used for composting or mulching.

BUFFERS

  • Reclaim™ II and Restore™ II should NOT be used over the top of desirable trees. They should only be used up to the drip line (outermost edge of the tree canopy) of desirable trees. Use additional caution around lateral root systems, shallow rooting species and those that propagate vegetatively through layering.



  • Grazon™ XC and Tordon™ 22K should NOT be used over the top of desirable trees. Applications should remain a distance of 1.5× the height of desirable trees at all times.
  • Do not apply Grazon XC or Tordon 22K to coarse texture soils (>40% sand) with a high water table (within 1.8 metres or 6 feet of the soil surface).
  • Do not apply Grazon XC or Tordon 22K within 30 metres (approximately 100 feet) of an open water body (does not include dugouts) or as per provincial regulations.

 

GRAZING AND CUTTING RESTRICTIONS

  • No grazing restrictions for livestock. Seven day grazing restriction for lactating dairy animals for Restore™ II, Reclaim™ II or Grazon™ XC; six weeks for Tordon™ 22K.
  • Withdraw all animals three days prior to slaughter.
  • If forage must be removed from an area treated with Restore II,Reclaim II, Grazon XC, or Tordon 22K, do not cut the forage within 30 days of application.
  • If livestock is being moved from a pasture treated with Corteva Agriscience range and pasture herbicides to a legume-based pasture it is recommended that animals be grazed on an untreated, non legume-based pasture for three days when treating with Restore II or Reclaim II and seven days when treating with Grazon XC or Tordon 22K.

Range and pasture products are designed for permanent pasture and rangeland where grazing is the method of harvest. The manure or compost from an animal fed treated forage should only be used on appropriate use sites where the loss of broadleaf plants, including legumes, can be tolerated.

RE-SEEDING AND GRASS TOLERANCE

Newly seeded grass

Newly seeded grass

Newly seeded grass should not be sprayed until secondary root development and a minimum of four leaf surfaces have established – well past the seedling stage.

Actively growing

Actively growing

  • Safe to established grasses.
  • Grasses may be seeded 10 months following an application.
  • Legume re-establishment may be affected for up to five years.
  • Soil organic matter, rainfall and temperature all affect the rate of degradation.

Not actively growing

Not actively growing

Avoid applications under stress conditions when grass is not actively growing (hot or cold weather,excessive moisture, or drought) as grass injury,including leaf discolouration and stunting of growth, in the season of application may result.

2019 Range and Pasture Stewardship Form

Stewardship REB8 Program: Customers purchasing eligible products on the Stewardship REB8 Program must complete this form in order to receive their rebate. See terms and conditions of 2019 Stewardship REB8 Program for product eligibility and program deadline.

Range and pasture products by Corteva Agriscience™, Agriculture Division of DowDuPont, are effective tools in managing weeds and brush in permanent pasture and grazed rangeland.

Understanding precautions, restrictions and how to steward range and pasture products properly is important to ensure satisfactory results and to protect desirable species and the environment.

In consideration of the sale of range and pasture products by Corteva Agriscience or its authorized distributors or retailers, the undersigned acknowledges receipt of the following information, cautions and restrictions.

Grazon™ XC (active ingredients: picloram and 2,4-D) is a herbicide that provides effective control of a broad spectrum of annual and perennial broadleaf weeds, brush and trees.

Tordon™ 22K (active ingredient: picloram) is a herbicide that is very effective for the control of deep-rooted, perennial and biennial weeds. It is essential to manage the use of Grazon XC and Tordon 22K effectively due to their persistent nature and non-selective control of broadleaf plants. For this reason, Grazon XC and Tordon 22K are sold for use on permanent grass pastures and labeled uses only.

Reclaim™ II (active ingredients: aminopyralid, Metsulfuron and 2,4-D) is a herbicide that provides effective control of a broad spectrum of annual and perennial weeds and woody shrubs.

Restore™ II (active ingredients: aminopyralid and 2,4-D) and Milestone™ (active ingredient: aminopyralid) are herbicides that provide effective control of a broad spectrum of annual and perennial broadleaf weeds. For this reason, Reclaim II, Restore II and Milestone are for use on permanent grass pastures and labeled uses only.

CAUTIONS AND RESTRICTIONS:

  • Prior to application, read and follow label directions.
  • Do not apply range and pasture products to garden or lawn areas. They are registered for permanent pasture only.
  • Most grasses are tolerant to Grazon XC, Tordon 22K, Reclaim II, Restore II and Milestone. However, some grasses may show temporary symptoms like yellowing or delayed growth following an application.
  • Do not apply any range an pasture products to areas where the elimination of legumes or other susceptible species cannot be tolerated.
  • When applying Grazon XC and Tordon 22K, leave a buffer zone of at least 1.5 times the height of desirable trees. When applying Reclaim II, Restore II or Milestone stay outside the drip line of desirable trees.
