Increased Risk of Downy Mildew on Onions

Marion Paibomesai, Vegetable Crops Specialist, OMAFRA
Michael Celetti, Plant Pathology Lead – Horticulture, OMAFRA

In Ontario, this disease is common in July and August and if left uncontrolled, quality and quantity of yield may be reduced. When cool, humid conditions are present particularly when the canopy of the crop is advanced, the risk of downy mildew increases. Foliar symptoms first appear as pale light green patches on infected leaves (Figure 1).

Increased Risk of Downy Mildew in Onions

Marion Paibomesai, Vegetable Crops Specialist, OMAFRA

Onion downy mildew has been found on onions in Waterloo and York Regions (updated 18 Aug 2014).  In Ontario, this disease is common in July and August and if left uncontrolled, the size, quality and quantity of yield can be significantly reduced. The neck tissue of the affected onions may not ‘cure’ properly at harvest and is thus open to secondary fungal and bacterial pathogens which can further reduce yield quality. When cool, humid conditions are present particularly when the canopy of the crop is advanced, the risk of downy mildew increases. Foliar symptoms first appear as pale light green patches on infected leaves (Figure 1).

Figure 1. A purple-grey downy growth often appears in the lesions after a period of wet weather or when conditions favour dew formation.
