Build a program →Can I tank-mix M1691?
It depends on your target weeds, crop stage, and which partners the label approves. Build a program and FieldMarshal checks the label for approved partners and gives the condition on each, so you can verify it.
Build a program →Plan in minutes, not hours.
Start with M1691 and let FieldMarshal build a defensible herbicide program for your field, every product, rate, and plant-back cross-referenced and checked against the label.
