- Dual II Magnum (metolachlor plus safener) controls annual grasses and pigweed, and
controls or suppresses waterhemp, black nightshade, and yellow nutsedge.
- Mode of action: shoot meristem inhibitor.
- Dual II Magnum can be applied preplant or preemergence before the crop and weeds emerge. Dual II plus atrazine can be
applied broadcast up to 5-inch corn or as a directed spray up to 12-inch corn, and before grass and broadleaf weeds exceed the 2-leaf stage.
Do not apply in liquid fertlizer after the corn has emerged.
- May be applied up to 30 days before planting as a single application. When applying 30 to 45 days before application, apply
2/3 full rate early, followed by 1/3 full rate at planting.
- Incorporation to a depth of 2 inches will improve yellow nutsedge control and reduce dependence upon rainfall.
