Resource Description
Cropping systems, including crop rotations, off-farm chemical inputs and mechanical and cultural tactics, can alter the volatile organic compounds (VOCs) emitted by crops, which serve as attractants or repellents for pests. The study found that wheat grown in rotation with fallow emitted greater amounts of certain VOCs, attracting a major wheat pest. However, the study also found that wheat grown in rotation with cover crops emitted more VOCs indicative of abiotic stress in the second year, potentially due to reduced water availability.
