For the week of July 15-19, 2019 there was no downy mildew reported in the Norfolk/Elgin or Kent County areas.
Looking at the IPM pipe website, the disease has now progressed as far north and New Jersey. Over the past week, there have been strong weather fronts originating in the Southern US. In the past, downy mildew often arrives in the great lakes basin after such events.
The 2019 downy mildew scouting program is funded by the Ontario Cucumber Research Committee. In Norfolk, the scouting services are provided by the Norfolk Fruit Growers Association. In Kent County, the program is managed by Tomecek Ag Services.
