John F. Tooker and Steven D. Frank Genotypically diverse cultivar mixtures for insect pest management and increased crop yields Journal of Applied Ecology 49
Intraspecific plant diversity can improve plant fitness via bottom–up and top–down effects on pest populations and niche partitioning. Further research is required to refine implementation practices and demonstrate value in terms of reduced pesticide use and increased yield. Growers can implement intraspecific crop diversity with minimal financial investment or changes in production practices. As the benefits of biodiversity for yield stability are increasingly recognized, intraspecific diversity is poised to become a prominent and sustainable management tactic.
