The Soybean Cyst Nematode (SCN) is a microscopic roundworm that primarily affects soybean plants. It is a significant pest in agriculture, causing reduced yields by feeding on the roots of the plants. The nematode enters the roots, forming cysts that contain eggs, which can survive in the soil for many years, making it challenging to control. SCN is often identified by yellowing leaves and stunted growth in affected soybean crops. Farmers can manage SCN through crop rotation, resistant soybean varieties, and soil testing to monitor nematode populations. Effective management is crucial for maintaining healthy crops and maximizing yields.
