July 5th, 2016: cucurbit downy mildew was identified today in a processing cucumber field in Kent County, Ontario. Now that the disease is present in the great lakes region, growers should immediately move to a targeted downy mildew spray program.
See the 2016 Downy Mildew Control Strategy for Cucumber Crops for an up-to-date list of registered control products.
Use only the downy mildew targeted products listed in the strategy. Research trials in Ridgetown, Simcoe and in the neighbouring states have shown these products to be the most consistent from year-to-year.
Rotate between all three of the targeted downy mildew products, starting with the most effective product, Orondis Ultra, and then rotate to either Zampro or Torrent within 7-days.
