Field Bindweed Management

quinclorac (Facet)

Rate 0.25-0.375 lb ai/A (22 to 32 fl oz/A Facet L))

Time Apply in fall after harvest but before a killing frost. Field bindweed should be actively growing and at least 4 inches long.

Remarks May be used on Kentucky bluegrass, annual and perennial ryegrass, and fine and tall fescue seed fields. Adequate soil moisture and/or light rain after application is required for root uptake. Repeat applications are necessary to maintain adequate control. Adding methylated seed oil or crop oil concentrate is required for consistent control. Nitrogen solutions or ammonium sulfate can be added to enhance control but should not replace the MSO or COC.

Caution Do not graze treated fields. Do not feed treated grasses, forage, hay, silage, straw, seed, or seed screenings to livestock. Do not apply by air west of the Cascades or in Spokane County, Washington.
