Late Blight Spores found in Ontario Spore Traps


High numbers of late blight spores were found in the filters of the two spore traps placed near Delhi, Ont. This area has received enough rain recently to create favourable conditions for disease development.

Keep the crop protected, especially new growth.  It’s the best way to reduce the risk of outbreaks.

Some early planted fields are being topkilled in Norfolk County. Tank mixing Reglone with Copper Hydroxide (e.g. Parasol) should ensure that spores landing on stem areas not killed by Reglone will be killed by Copper.  The label states that Parasol should not be applied within 2 days of harvest.
