Pests
Numerous pests affect commercial grain, forage and livestock production in New York. All stages of crop growth may be susceptible to insects, weeds or disease causing pathogens which may result in poor seedling emergence, reduced yields and quality issues. Similarly, livestock are affected by nuisance insects, parasites and diseases both in the barn and out on the pasture. Correct pest identification is a crucial step in developing an integrated pest management program on your farm.NWNY Dairy, Livestock and Field Crops 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 crop and livestock pests can be found below. Additional information can be found under the pest categories of Diseases, Insects, and Weeds.
