Food crops such as rice, maize and cabbage are grown over two-thirds of Korea’s total arable land. Damage inflicted by soil-borne insects threatens yields, with losses of up to 30%. The proliferation of these pests is the result of a lack of safe, feasible control methods. This project aims to improve pest management through making an effective, low-cost biological control agent – insect-killing nematodes (microscopic worms) – locally available.
