The proven and consistent standard for advanced disease control in corn, soybeans and alfalfa, with the additional benefits1 of AgCelence®.

  • The same, unique AgCelence benefits1 found in Headline® fungicide including greener leaves, stronger stems and stalks and better management of minor heat, cold, and drought stress, all leading to higher yield potential.2
  • Includes the active ingredient Xemium® for more consistent and continuous protection against disease.
  • Multiple modes of action for broad-spectrum disease control as part of a resistance management plan.

Disease Management

See label for all details on diseases controlled or suppressed.

Crop Disease
In alfalfa. Blossom blight (Sclerotinia sclerotiorum)5
Common leaf spot (Pseudopeziza medicaginis)
In corn (field, pop, seed and sweet) Common rust (Puccinia sorghi)
Gray leaf spot (Cercospora zeae-maydis)
Northern leaf blight (Setosphaeria turcica)
Eye spot (Aureobasidium zeae)5
In soybeans. Asian soybean rust (Phakopsora pachyrhzi)
Frog eye leaf spot (Cercospora sojina)
Septoria brown spot (Septoria glycines)
Sclerotinia stem rot (Sclerotinia sclerotiorum)5

1 AgCelence benefits refer to products that contain the active ingredient pyraclostrobin.
2 All comparisons are to untreated, unless otherwise stated.
3 While Priaxor can be applied at earlier growth stages, research suggests the stated timing provides optimal AgCelence benefits.
4 Maximum of two applications per season.
5 Suppression only.

Priaxor Fungicide

Introducing Priaxor, a unique chemistry for corn and soybeans.

Your corn’s got potential. It’s time to realize it.

Realizing your corn’s yield potential doesn’t depend on genetics alone. Explore innovative solutions to help you tackle weeds and diseases all through the season.

Solutions For Soybeans

Keeping soybean fields clean comes down to choosing the right tools.

When it comes to soybeans, you’ve got standards. Get ready to exceed them.

Growing soybeans takes knowledge, hard work and dedication – and no one knows it better than you. Learn about major crop production challenges and explore best-in-class solutions for every stage of your operation.

How it Works

  • Priaxor provides two modes of action: Group 11 pyraclostrobin (same active found in Headline) and a new Group 7 active ingredient, Xemium for broad-spectrum activity with curative, preventative and residual effects.
  • The active ingredients work together across multiple stages of fungal growth to inhibit spore germination, mycelial growth and sporulation.
  • In addition, Priaxor provides the unique benefits of AgCelence for larger, greener leaves, stronger stalks and stems and better management of minor heat, cold and drought stress, all leading up to increased yield potential.

Application Tips

Rainfastness - 1 hour.

Priaxor should be applied preventively, prior to the onset of disease.

While it can be applied at earlier growth stages, research suggests the stated crop-stage timing is optimal for AgCelence benefits,1 including disease control.


Pre-harvest interval

7 days after application for sweet corn.
14 days after application for alfalfa.
21 days after application for corn and soybeans.


1 AgCelence benefits refer to products that contain the active ingredient pyraclostrobin.
2 All comparisons are to untreated, unless otherwise stated.

When to Apply

Priaxor should be applied preventively, prior to the onset of disease. While it can be applied at earlier growth stages3, research suggests the following timing for optimal disease control and AgCelence benefits.

Crop Staging3
Alfalfa 10 to 20 cm (4 to 8 inch) height4
Corn Pre-tassel to full tassel
Soybeans Early flower to mid-pod development (R1 to R3)

3 While Priaxor can be applied at earlier growth stages, research suggests the stated timing provides optimal AgCelence benefits.
4 Maximum of two applications per season.

How Much to Apply

Please refer to product label for full rate, mixing and application information.



Water volume

Ground application 40 to 80 L/ac (10 to 20 gal/ac)8
Aerial application9 20 L/ac (5 gal/ac)

8 Use higher water volumes to ensure adequate coverage and better activity on leaf disease.
9 Class 2 pesticides, such as Priaxor, require a permit to be applied by aerial application in Ontario. No permit is required for an application on ground.



Mixing order
  1. Ensure the spray tank is clean before use.
  2. Fill the spray tank half full of water and start agitation.
  3. Add the required amount of Priaxor fungicide to the tank.
  4. Continue agitation while filling the remainder of the spray tank.
  5. After use, clean the spray tank according to label precautions.
