Seeker 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 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 MO and ND.
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.
Seeker FAQ
What weeds does Seeker control?

What crops is Seeker labeled for?

What is the active ingredient in Seeker? Is it a generic?
Seeker's active ingredient is mesotrione (MOA Group 27). Other products list the same active ingredient; rates, formulations, and labeled crops differ — verify each on its own label.
What's the plant-back interval after Seeker?
It depends on your rotational crop, application rate, and region, so the label gives a table, not one number. Build a program and FieldMarshal gives you the exact interval for your rotation from the label line, so you can verify it.
Build a program →Can I tank-mix Seeker?
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.
