Showdown 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 AL, AR, CA, CO, FL, GA, KS, LA, MO, MS, NC, ND, NE, OK, SC, SD, TN, TX, VA, and WY.

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.

Showdown FAQ

What weeds does Showdown control?

The Showdown label names 144 weeds, including alfalfa, spurred anoda, jerusalem artichoke, bahiagrass, balsamapple, and barley. Control varies by crop, rate, and timing.

What crops is Showdown labeled for?

Showdown is labeled for 33 crops and uses, including field corn, soybeans, wheat, cotton, and potato.

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

Showdown's active ingredient is glyphosate (MOA Group 9). 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 Showdown?

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 Showdown?

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.
