Harvest is underway on all farms with some growers still working on the first pass while others are on their second pass. The quality of tobacco cured so far appears good. There are no widespread problems being reported at this time. Currently, pressure from aphids and hornworms is not very significant in most fields. A few plants in some fields are showing infection from Potato Virus Y (PVY). White Mould (Sclerotinia sclerotiorum) is also being seen on a few plants in some fields as well. Certain varieties are showing more spotting (1-3 mm in diameter) on field leaves than others. The cause of this is from air pollutants and the variety’s susceptibility to this injury. The spots are initially brown or black and eventually will turn to grey or white. To date, there have been no reports this season of Blue Mold in Ontario.
