Soybean Cyst Nematode in NY
Katelyn Miller, Field Crops and Forage Specialist
Southwest New York Dairy, Livestock and Field Crops Program

Compiled from presentation by Erik Smith, CNY Field Crop Specialist
Soybean Cyst Nematode (SCN) is a plant-parasitic roundworm that feeds on the roots of various hosts such as beans (soy and dry), peas, and clovers. Its feeding slows root growth and decreases the uptake of water and nutrients. The symptomology of this pest is dependent on population density, soil texture, fertility, and rainfall. Often, damage can be confused with nutrient deficiencies, herbicide damage, and environmental stress. Due to the root feeding nature of this pest, soil-borne pathogens like white mold and sudden death syndrome are often introduced to the plant. The most common symptom though is stunted growth above ground, accompanied by yellow, wilted plants.
Native to Japan, the pest has now spread throughout NY and is the #1 yield reducing pest of soybean. In 2016, the first NY county identified it; today that total is up to 38 counties in NYS. So, how do you know if you have SCN present in your field(s)? The only sure way to know is by taking samples and sending them into a lab for analysis. This pest can cause a 30% reduction in yield with no above-ground symptoms, so taking samples can be a preventative measure to ensure that you are getting the most from your soybeans.
