A recent study from Penn State's College of Agricultural Sciences revealed that different cover crops can influence plant defense mechanisms against pests. Published in Basic and Applied Ecology, the research showed that plants grown in soil previously used by pea cover crops emitted more indole, boosting stress hormones and defensive chemicals, but had lower levels of benzoxazinoid, a natural pesticide. These findings highlight the potential for cover crops to impact plant resilience and pest management strategies, offering valuable insights for climate solutions experts seeking sustainable agricultural practices.
