“Downy mildew on cucumber has been verified in three cucumber producing counties on the west side of Michigan and one pickling cucumber producing county on the east side of Michigan.”
“Cantaloupe crops are also at risk of becoming infected by downy mildew and should be protected using the fungicides that have been proven to be effective in MSU research cucumber field studies.”
