DuPont BL1 rates and plant-back
The label answers both with a table, not a single number. Here is what drives each answer.
Application rate
Your rate depends on your crop and your soil texture.
Get the rate for your field: build a program and FieldMarshal gives you the exact per-acre rate for your crop from the label line.
Plant-back and rotation
Your interval depends on your application rate, the rotational crop, and your state, region, and rainfall — some intervals differ in CO, KS, ND, NE, NM, OK, OR, SD, TX, and WY.
Get the interval for your rotation: build a program and FieldMarshal gives you the exact plant-back for your rotational crop from the label line.

Build a program →Can I tank-mix DuPont BL1?
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 DuPont BL1 and let FieldMarshal build a defensible herbicide program for your field, every product, rate, and plant-back cross-referenced and checked against the label.
