Garlic and Onion Diseases

Wednesday, July 4, 2012

I wrote about white rot and its risk to garlic industry in Nova Scotia. That threat is still real and growers should be using only seed from clean seed program.

Aside from white rot, there are other garlic diseases which can be devastating to garlic crop, namely botrytis and downy mildew. I have already seen some heavy botrytis disease pressure in commercial garlic crop plantings. Warm and humid weather is very conducive for disease development.

Botrytis and downy mildew are serious crops of onions and growers must apply fungicides to keep those diseases to the minimum.
