Disease Control Challenge

Devastating yield losses from Sclerotinia in Canola
Sclerotinia sclerotiorum is a constant threat in the primary canola producing regions of Canada. Yield losses every year range in the millions of dollars. Scouting and forecasting for the disease is difficult and foliar control options are costly.

Nufarm Solution

  • Integrated pest management. Delivers the right level of protection as part of an Integrated Pest Management strategy, including hybrid trait tolerance, to deliver the level of protection required by your crop in your fields
  • Pulse protection. Excellent solution for powdery mildew, white mold, ascochyta blight in pulse crops, and early blight and white mold in potatoes
  • Active Ingredient: 
    • Group 3 (metconazole)
  • Rainfast: 
    • 2 hour
  • Treatment area: 
    • One case treats 80 acres
  • Tank-mix order:
