According to USDA records, pickling cucumber acreage declined nearly 25 percent between 2004 and 2015. Globally, downy mildew threatens fields as far flung as India, Israel, Mexico and China.
“This is the number one threat to the pickle industry,” says vegetable pathologist Lina Quesada-Ocampo of North Carolina State University. The growers, she says, lose money on failed crops and pricey fungicides. “It is a really bad double whammy.”
Fortunately for pickle lovers, vegetable breeder Michael Mazourek of Cornell University is close to releasing varieties that resist downy mildew.
