Drill 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

Drill FAQ

What crops is Drill labeled for?

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

Drill's active ingredient is diuron (MOA Group 5). 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 Drill?

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.

Can I tank-mix Drill?

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.
