Paramount for Field Bindweed Control
Quinclorac (Paramount) provides excellent field bindweed control (Table 2) and should be applied with a methylated seed oil at 1.5 to 2 pints per acre. Ammonium sulfate at 2.5 pounds per acre or urea ammonium nitrate may also be added. Quinclorac may also control foxtails, barnyard grass, and volunteer flax.
Quinclorac may carryover in soil for one year or more. Most crops may be planted 10 months after quinclorac application except flax, chickpea, dry pea, and sugarbeet which require a 24-month interval between application and seeding. Consult the label for complete rotational restrictions.
