Benefits of Cotegra

Cotegra fungicide inhibits spore germination and also inhibits mycelial growth and sporulation of the fungus on the leaf surface. It can be applied in either pre- or post-infection, however, optimum disease management is achieved when it is applied preventatively in a scheduled protective spray program.

Application Tips

Rainfastness – Avoid applying when rain is forecasted within 3 hours of application.

Pre-harvest interval
36 days after application for canola, Oriental mustard and rapeseed.
21 days after application for lentils, field peas, chickpeas, dry beans, and soybeans.

When to Apply

Crop

Staging

Canola, Oriental mustard, rapeseed         

20 - 50% flowering

Chickpeas, field peas, lentils

Beginning of flowering or at first sign of disease

Dry beans1

20 - 50% flowering

Soybeans

Prior to disease development (late R1/R2 to R3)

 

Note: A 2nd application can be made 7 to 14 days after 1st application if disease persists, or weather conditions favour disease development. Use the shorter interval when disease pressure is high to obtain extended protection and maximum yield benefit.

FAQ

What are the scouting tips to detect sclerotinia?

  • Around mid-June before flowering, look for apothecia (golf-tee shaped mushroom structures) under the canopy. Spores are shot in the air and can move locally and in nearby fields. If you find signs of sclerotinia, it’s already too late. This is why consistent scouting and fungicide timing is so important.
  • Weather; cool moist periods increase risk. At around 10-11am walk through in a w-pattern. The bottom of your pants will be wet from dew showing moisture.
  • Risk also increases with these factors:
    • Number of susceptible crops planted in 3-4 years rotation
    • Density of canopy; healthy vigorous crop have higher risk
  • Fungicide prevention:
    • At the 20-30% bloom stage (15-20 open pods) it’s ideal to apply a fungicide.
    • Make sure to continue monitoring highest yielding areas.

What are the symptoms to scout for when identifying sclerotinia?

Around mid-June before flowering, look for apothecia (golf-tee shaped mushroom structures) under the canopy. Spores are shot in the air and can move locally and in nearby fields. If you find signs of sclerotinia, it’s already too late and preventative disease control is not possible.

What is the ideal temperature for storing fungicides and what is the freezing point?

The ideal temperature for storing fungicides is above the freezing point at 0°C. See page 228 in the Agricultural Solutions Guide.

When is the best time to apply Fungicide on my crop?

Nexicor® fungicide should be applied early at the 2 to 6 leaf stage.  Lance® and Cotegra® fungicides should be applied at the 20-50% flowering stage.

What are the best practices for storing fungicides?

  1. Store the leftover product in original tightly closed container. Protect from freezing.
  2. DO NOT ship or store the product near food, feed, seed and fertilizers.
  3. Store the product in a cool, dry, locked, well-ventilated area without a floor drain.

Where can I find the tank cleaning recommendations?

Tank clean out recommendations can be found on the product label.

What are the differences between Cotegra®, Lance and Nexicor® fungicides?

Each fungicide has one or more unique mode(s) of action, controls a different disease(s) and is applied at specific crop staging.

 

Nexicor fungicide controls blackleg and contains three active ingredients, including Group 3,7 and 11. It can be applied early at the 2 to 6 leaf stage.

 

Lance fungicide contains a Group 7 active ingredient and controls alternaria black spot and sclerotinia. Cotegra fungicide contains Group 7 and 3 active ingredients and controls sclerotinia in canola. Both of these fungicides can be applied at the 20-50% flowering stage.

Are there any registered follow crops for Cotegra, Lance and Nexicor fungicides?

No, there are no registered follow crops for Cotegra, Lance and Nexicor fungicides.

What is the correct mixing order? (tank mixes with herbicides, fungicides, insecticides, surfactants)

Mixing order for Cotegra® fungicide:

  1. Fill the cleaned spray tank 1/2 full of water and start agitation.
  2. Add the required amount of Cotegra fungicide to the tank.
  3. Continue agitation while filling the remainder of the spray tank.
  4. After use, clean the spray tank according to label precautions.

What are the application tips for using Cotegra fungicide?

Cotegra fungicide:

  1. Rainfastness is important, and application should be avoided when rain is forecasted within 3 hours of application.

What are the recommended water volumes and application rates for fungicides?

For aerial applications, the recommended water volume for all fungicides is 20 L/ac (5 gal/c). For ground applications with Lance or Nexicor fungicides, the recommended water volume is 40 L/ac (10 gal/c). Whereas for ground application with Cotegra fungicide, the recommended water volume is 40 to 80 L/ac (10 to 20 g/ac). Higher water volume is recommended for optimal coverage.

What are the best conditions to look for when applying Cotegra® fungicide on canola?

Restrictions/conditions for Cotegra fungicide application in canola:

  1. DO NOT apply during periods of dead calm.
  2. Avoid application of this product when winds are gusty.
  3. For aerial application, DO NOT apply when wind speed is greater than 16 km/hour at flying height at the site of application.
  4. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification. For ground application, boom height must be 60 cm or less above the crop or ground.
  5. For aerial application, to reduce drift caused by turbulent wingtip vortices, the nozzle distribution along the spray boom length MUST NOT exceed 65% of the wing- or rotorspan.

Can I still apply Cotegra fungicide on canola that is at the late flowering stage?

Cotegra fungicide is most effective when applied at the recommended 20-50% flowering stage. Applying at the late flowering stage may be too late.

At which crop stage should I be spraying a fungicide?

  • If you're using Nexicor fungicide, you should spray between the 2-leaf and bolting stage.
  • For Lance or Cotegra fungicides, you should spray between the 20-50% flowering stages.
