‘From superfood to super crop’: Univ of Idaho researchers find promise in quinoa as rotation crop to curb PCN

Researchers at the University of Idaho have identified quinoa, often hailed as a “superfood,” as a potential solution to the pale cyst nematode (PCN) infestation plaguing potato farmers in eastern Idaho. Quinoa, which has seen a surge in cultivation in the region, functions as a “trap crop” by stimulating the PCN to hatch without providing a viable host. This reduces the nematode’s viability in the soil. While another plant, the litchi tomato, has shown even greater effectiveness in combating PCN, it lacks the economic advantages of quinoa.
