Nightshade Management Reduces Crop Loss
Julie Kikkert, Team Leader, Extension Vegetable Specialist
Cornell Vegetable Program
For processing pea growers, nightshades can turn to nightmares as many fields with bountiful pea crops can be rejected by processors at harvest time because nightshade berries have similar size and shape as peas. Similar crop loss can occur in beans where nightshade berries stain and cause soil to stick to pods. Nightshades should be managed in other crops as well because they reduce crop yields, and harbor diseases of Solanaceous crops such as early blight and late blight of potatoes and tomatoes. Nightshades may become more of a problem in NY if early, warm spring weather becomes a more frequent pattern.
