Benefits

Take on large, dense leafy spurge infestations

Success against leafy spurge requires a strategic approach. Broadcast applications of Graslan® L herbicide will thin leafy spurge stands each year, increasing grass production and improving forage utilization. When spot-treating small patches or where new infestations pop up, go with the rate flexibility of Tordon® 22K herbicide. The goal with spot treatments is to eliminate the patch as quickly as possible.

High-load, low-odor formulation

Graslan L is a convenient premix of the active ingredient in Tordon 22K plus 2,4-D choline. Research shows that including 2,4-D in treatments with Tordon 22K improves leafy spurge control in-season and long-term.

Graslan L is a low-odor, high-load formulation, allowing for a lower use rate and less packaging. The formulation also is less volatile and carries a reduced signal word, compared with the old standard, Grazon® P+D herbicide.

Nip patches in the bud

Success against leafy spurge requires a strategic approach. Broadcast applications of Graslan L will thin leafy spurge stands each year, increasing grass production and improving forage utilization. When spot-treating small patches or where new infestations pop up, go with the rate flexibility of Tordon 22K. The goal with spot treatments is to eliminate the patch as quickly as possible.
 

Broadcast recommendation:

  • Apply 2.5 to 5 pints of Graslan L herbicide per acre
  • Two to three annual treatments are necessary for control; be sure to treat at least two consecutive years.
  • Monitor the treated area and reapply when the level of control falls below 80 percent.

Spot/patch recommendation:

  • Apply 2 to 4 quarts of Tordon 22K per acre
  • Use the higher rate in the rate range for older patches or inaccessible areas.
  • New patches often establish on the perimeter of the main infestation. They must be eliminated to contain the spread. Treat 15 feet beyond infested area to capture the full extent of the infestation in the application.
