About this Product

Double-duty disease control
Unlike other leading single-mode-of-action fungicides, Astound is the only fungicide that does double duty on canola.  With its two complementary modes of action - one contact and one systemic - Astound protects your canola from the outside in and the inside out, making it the most complete protection available against Sclerotinia.

 

Product Benefits

Astound fungicide protects your canola.

  • Works on contact to kill active disease spores and prevent them from germinating
  • Works systemically within the plant to protect new growth
  • Provides two modes of action for resistance management
  • Complete protection available against Sclerotinia sclerotiorum
  • Registered for aerial application
  • Provides exceptional crop safety

Uses

canola

For management of

Sclerotinia sclerotiorum (Sclerotinia stem rot).

Sclerotinia stem rot is the most economically significant disease of canola in Western Canada. Sclerotinia sclerotiorum, the fungal pathogen that causes the disease has staying power in the soil and, with the right combination of weather and crop conditions, can cause heavy infections in all canola growing regions of Western Canada.

Yield loss occurs through: 

  • Smaller and fewer seeds 
  • Shrunken seeds 
  • Premature ripening of infected stems 
  • Shattering
     

What is Sclerotinia costing you?
The presence of sclerotinia in your canola crop equates to lost bushels, which equates to lost yield.  That's why a preventative approach is so important.  And that's why there is such value in an application of Astound.

To calculate the potential yield loss per acre from sclerotinia, multiply the amount of               infection (%) by 0.5.  In 2010, the average incidence of sclerotinia across the 3 provinces was 22%1.

1. Yield loss due to sclerotinia:  22% infection x 0.5 = 11% yield loss

2. Potential $ yield loss per acre:  11% yield loss x 45* bu/ac x $14**/ac = $69/ac

3. ROI: $69 - $30/ac (Astound SRP $22/ac plus aerial application costs $8/ac)
           = $6,240 per quarter section

Application Information

Timing makes the difference
Application timing is very important to ensure best control against Sclerotinia sclerotiorum (stem rot) in canola. Because it infects petals first, Astound® fungicide should be applied during crop bloom to cover as many petals as possible, while ensuring that it penetrates into the canopy to help protect potential infection sites. Ideally, application should be at 20–50% bloom, depending on local weather conditions, Sclerotinia risk maps and emergence of apothecia (the cup-shaped body that discharges the infection spores) in the area.

Follow the steps below to identify the stage of your crop:

  1. Locate the main stem.
  2. Remove the secondary branches.
  3. Count the open flowers on the main stem, including aborted flowers and newly formed pods.
  4. Take a sample from several plants across the field.
  5. Multiply the number of flowers and pods on the main stem and multiply by two.  (For example, 10 open flowers on the main stem x 2 = 20% bloom.)

Mixing Order

  1. Add 1/2 the required amount of water to the mix tank.
  2. With the agitator running, add the required amount of Astound.
  3. If using, add the required amount of Matador.
  4. Continue agitation while adding the remaining amount of water.
  5. Begin application after the Astound has completely dispersed into the mix water.
  6. Maintain agitation until all of the mixture has been applied.

Use Restrictions

Application

  • Avoid application of more than two consecutive sprays of Astound or other Group 9 and 12 fungicides in the same season
  • Do not apply during periods of dead calm. Avoid application of this product when winds are gusty

Re-cropping

  • Do not plant any other crop for a period of 30 days after harvest or crop failure unless Astound is registered for that use

Pre-harvest interval

  • 35 days

Storage

  • Store in a dry place

Tank Mixes

Astound can be tank mixed with Matador® for insect control.

Mode of Action

Astound contains fludioxonil, an active ingredient that works on the plant surface to inhibit spore germination. It works on contact, working from the outside in, providing preventative protection from infection.

The 2nd active ingredient in Astound is cyprodinil, a potent systemic fungicide that inhibits a pathogen’s ability to penetrate plant tissue and form mycelia. It’s gradually absorbed into the plant and moves through leaf tissue into the xylem, the plant’s water conducting system where it moves up and out into new growth. It works from the inside out, to provide curative protection against Sclerotinia in canola.

Because it works inside and outside the plant, Astound provides more effective, thorough protection against Sclerotinia in canola.

Resistance Management

Astound is the only canola fungicide with two modes of action (Group 9 and Group 12 fungicides) to provide better resistance management on your fields while controlling disease.
