Pests

PestsNumerous pests affect commercial vegetable production in New York. All stages of plant growth may be susceptible to insects or disease causing pathogens which may result in poor seedling emergence, reduced yields and quality issues. Similarly, weeds compete with vegetable crops for light, nutrients and water often reducing yields. Weeds can also act as a reservoir for insects and diseases. Furthermore, weed seeds and other parts can be a contaminant of certain vegetable crops.

Cornell Vegetable Program Specialists conduct research and educational programs on many important insects, diseases and weeds in New York. While not an exhaustive list, current information on many important vegetable pests can be found below. The most recent pest content is listed below but you can find more pests under the pest categories of Diseases, Insects, and Weeds.

    Video: Downy Mildew

    Downy mildew is a potentially devastating disease to cucurbits. It usually affects cucumbers and cantaloupes first; later in the season it can be found on summer squash and zucchini. During some seasons, downy mildew can spread to winter squash and watermelons. Growers need to be monitoring their fields. This short video shows the different stages of the disease and possible outcomes if it is not controlled.
