In Wheat, In Wheat Year / Wheat Stubble
Treatment After Harvest or in Fall
Bindweed may be treated in wheat stubble immediately after harvest with a tank mix of eight ounces Picloram (Tordon 22k or Outpost 22K) with 32 ounces of 4# 2,4-D Amine per acre on land that will be summer fallowed next year.

We recommend the use of the 16 ounces of Picloram with the 2,4-D Amine if you are treating the property for the first time with Tordon. If you have treated the property in the previous year with Picloram then we recommend that you only use the eight ounces of Picloram with the 2,4-D Amine to avoid a buildup of Picloram in the soil that may start causing wheat damage.

We also recommend that if the bindweed is under drought stress or if the weather is hot and dry, that you delay treatment with Picloram by either tilling the bindweed until fall or spraying with just one quart of 2,4-D Amine or Landmaster now, and using the tankmix of Picloram and 2,4-D Amine in the fall after the first light frost if the land is to be summer-fallowed the next year.

Bindweed should be sprayed by ground application equipment with 20 gallons of water per acre or maximum amounts of surfactants when less than 20 gallons is used. Persistence over the course of many years is the only thing that can kill an established bindweed plant.

Other Mixes
Picloram may be applied tank-mixed with Landmaster instead of 2,4-D Amine to control other broadleaf weeds and grasses in the stubble. Landmaster is not available for cost share through the County.
