The frequent rains, heavy dews, fog, overcast skies and moderate temperatures have promoted infections by downy and powdery mildew. Strictly protectant fungicides cannot stand up to the heavy rains that have occurred this year. Dense canopies prevent air movement to dry off foliage and fruit and also impair good deposition of sprays.

Spotted wing Drosophila (SWD) populations usually start to soar in late-July, after the majority of the tart cherry crop is harvested. However, numbers rose quickly this year, reaching levels much higher than normal by the time cherries started to colour. Eight cherry blocks in Niagara were monitored for SWD using apple cider vinegar traps (ACV). Each week the traps were emptied and refilled and the number of SWD counted. We have used ACV as a bait in our monitoring programs since 2011, and while it is cost effective and easy to obtain work with, it is not very selective or effective at attracting SWD at low population densities. For this reason, we have recommended protective sprays for ripening fruit when SWD is present in a region (SWD + ripening fruit = spray).
