Roundup PowerMAX 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 AZ, CO, KS, NE, NM, OK, OR, SD, TX, 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.
