Fusarium Basal Plate Rot of Onion in 2016

Michael Celetti, Plant Pathologist – Horticulture Crops (OMAFRA)

Basal plate rot is beginning to show up in some onion fields in Ontario due in part to the warm 2016 growing season. The causal agent of basal plate rot, Fusarium oxysporum f.sp. cepae, is not new to Ontario. It is a persistent soil-borne organism that can also contaminate onion sets or cloves of garlic used for seed. In fact it is most likely introduced into non-contaminate fields on infested garlic cloves or onion sets. The disease tends to occur more frequently on Spanish onions varieties than on yellow cooking onion varieties. Continue reading Fusarium Basal Plate Rot of Onion in 2016

Increased Risk of Downy Mildew on Onions

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).
