Intensity 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, NY, OR, 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.

Intensity FAQ

What weeds does Intensity control?

The Intensity label names 63 weeds, including annual bluegrass, barley, common barnyardgrass, bentgrass, bermudagrass, and perennial bluegrass. Control varies by crop, rate, and timing.

What crops is Intensity labeled for?

Intensity is labeled for 26 crops and uses, including field corn, soybeans, cotton, sunflower, and potato.

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

Intensity's active ingredient is clethodim (MOA Group 1). 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 Intensity?

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.

Can I tank-mix Intensity?

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.
