Capreno Herbicide FAQ

Capreno Product Overview

What is Capreno herbicide?

Capreno® herbicide is a powerful, postemergence herbicide that provides growers with reliable, broad-spectrum weed control. Capreno delivers burndown control of grass and broadleaf weeds and provides long-lasting residual control to keep crops safe all season long.

Visit the Capreno product page for more details on Capreno herbicide.

How does Capreno work?

Capreno contains two sites of action – an HPPD inhibitor (Group 27) and ALS/AGAS enzyme inhibitor (Group 2) – to help with managing resistance.

What crops is Capreno registered on?

Capreno is registered for use in corn, including field corn, field corn for silage, seed corn and white corn.

Which weeds does Capreno control?

Capreno manages a number of tough-to-control driver weeds, including green and yellow foxtails, waterhemp, Palmer amaranth, kochia, giant ragweed, marestail and lambsquarters. Explore the full list of weeds controlled by Capreno.

Capreno Application and Use

When should Capreno be applied?

Capreno has a wide window of application, from the V1 corn growth stage up to 20 inches tall. Do not apply if the crop is more than 20 inches tall or at the V7 stage, whichever is more restrictive. Broadcast applications for corn grown for seed are recommended from the V1 to V5 growth stages. For full application instructions, consult the Capreno label.

What is the use rate?

Good coverage is essential to achieve optimum weed control. In postemergence applications, apply Capreno herbicide at 3 fl oz/A per application. Lower rates may result in incomplete weed control and reduction in residual activity. Capreno should be applied in a minimum of 10 gallons of water per acre. For weed control in dense weed populations or under adverse growing conditions, apply this product in 15 to 20 gallons of water per acre. For full application instructions, consult the Capreno label.

What are the recommended tankmix partners?

Tankmixing multiple effective sites of action is an important step to helping manage weed resistance. Adding a burndown herbicide to your tank, such as Roundup® or DiFlexx®, is recommended. The addition of atrazine in the tank mixture will further improve control of certain weeds by increasing the speed, spectrum and consistency of the weed control. Do not use atrazine if corn is more than 12 inches tall. Learn more about how an integrated weed management program can help you manage weeds and resistance.

For convenience and excellent disease control, Capreno can also be tankmixed with Delaro® fungicide or Stratego® YLD fungicide. Check the Capreno label for more information on tankmixing and tank mix partners.

Does Capreno need any adjuvants or surfactants?

Capreno herbicide is a suspension concentrate that requires the use of an external adjuvant and a nitrogen fertilizer source to achieve optimum weed control when weeds are present at the time of application. For specific adjuvant recommendations with tank mixtures, see the Capreno label.

What is the maximum amount of Capreno that can be applied in one year?

Do not exceed a total of 6 fl oz/A of Capreno per 365 days for all corn types.

What is the rainfastness?

Capreno herbicide is rainfast 1 hour after application to most weed species.

Capreno Product Safety

Is Capreno safe for the crop?

Capreno herbicide contains a safener, which greatly reduces or prevents the temporary yellowing or stunting crop response associated with applying this herbicide postemergence. If symptoms appear, corn quickly outgrows the effect and develops normally.

What are the crop rotation restrictions?

A number of rotational crops may be planted after applying Capreno herbicide in corn. You can replant corn immediately after a Capreno application, wheat after four months and soybeans after 10 months. Other crops, such as peanuts, alfalfa, beans and sugar beets have longer rotational intervals. Plant-back intervals specific to various crops are outlined in greater detail on the Capreno label.
