Express 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.
Get the rate for your field: build a program and FieldMarshal cites the exact per-acre rate for your crop to 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 ID, MN, OR, UT, and WA.
Get the interval for your rotation: build a program and FieldMarshal cites the exact plant-back for your rotational crop to the label line.

What crops is Express labeled for?

What is the active ingredient in Express? Is it a generic?

What's the plant-back interval after Express?
It depends on your rotational crop, application rate, and region, so the label gives a table, not one number. Build a program and FieldMarshal cites the exact interval for your rotation to the label line, so you can verify it.
Build a program →Can I tank-mix Express?
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 cites the condition on each, so you can verify it.
