Helpful Disease Survey Data for Local Corn & Soybean Farmers

As Northern New York farmers scout corn and soybean fields for any diseases that may impact crop health and yield, they can use five years’ worth of survey results as a guide to newly-emerging and common crop pathogens in Clinton, Essex, Franklin, Jefferson, Lewis and St. Lawrence counties.

The corn and soybean disease survey project is funded by the farmer-driven Northern New York Agricultural Development Program. In addition to identifying current areas of concern and trends, the project provides regional farmers with the expertise of Cornell Cooperative Extension specialists who scout 12 sentinel fields of corn and 21 sentinel fields of soybeans. These fields on Northern New York Farms represent different soils and growing conditions, and a variety of cropping practices.

Fields are assessed at various stages of crop growth. The Bergstrom Lab at Cornell University in Ithaca, N.Y., has cultured and analyzed field samples since 2013.

“Multi-year surveys better capture variations in weather from year-to-year, from a wet spring to drought in the past five years. The data helps farmers make more informed corn and soybean variety selections, evaluate soil and crop debris for potential problems, and plan management strategy,” said project leader and Cornell plant pathologist Dr. Gary C. Bergstrom, Ithaca, N.Y.

This disease survey project was started in 2013 as the first systematic assessment of corn and soybean diseases conducted in Northern New York in recent decades.
