Sclerotinia diseases are very difficult to control using in-season foliar treatments. The sclerotia (resting bodies) of Sclerotinia can persist for several years in the soil and continue to cause infection of sensitive crops.
There are two main Sclerotinia species:
Sclerotinia sclerotiorum can infect many crops, particularly oilseed rape, lettuce, carrot, potatoes, beans (field and fresh), peas (combined, vining and fresh), vegetable brassicas and celery.
Sclerotinia minor particularly infects lettuce. It produces more, but smaller sclerotia and requires more intensive treatment than Sclerotinia sclerotiorum.
Based on a naturally-occurring fungus, Coniothyrium minitans, Contans WG reduces disease loading by attacking and destroying the sclerotia and mycelial growth (seen as white mould) in the soil. Applied pre-planting, it effectively cleanses the soil of Sclerotinia, improving its health within the crop rotation.
You can use Contans WG as part of an IPM (Integrated Pest Management) or ICS (Integrated Crop Solution) programme for lasting protection from Sclerotinia disease within the rotation. Indeed, it is an ideal complement to foliar treatments such as Nativo 75WG, Rudis or Serenade ASO (under EAMU 20130706*).
