Potatoes

“European corn borer (ECB) is a major pest insect of many different host crops in the United States, including the northeast. These include sweet and field corn, snap beans, peppers, potatoes, apples, hemp, small grains and ornamental plants.”

“This pest is a threat to strawberries and will also damage peaches, pears, raspberries, apples, and grapes, as well as beans, beets, cabbage, cauliflower, celery, cucumbers, potatoes, turnips, and many ornamentals.”

“Incorporate diseased vines after harvest and avoid growing pepper, tomato, and potato in a continuous rotation.”

Yield was the same as, or moderately reduced from, the standard herbicide control plots in the two-year study. Hairy vetch, woollypod vetch, oats, barley, and an oats/ hairy vetch mix were suppressed as needed with fluazifop and metribuzin (341).”
