Educational challenges with the use of biopesticides: Grower expectations of product performance

Biopesticides are broadly classified into three main categories: microbial pesticides, biochemical pesticides, and plant-incorporated protectants (PIPs). A prime example in potato management is the novel dsRNA, Calantha. A key advantage of biopesticides is their high target specificity, which minimizes harm to non-target organisms like beneficial insects, wildlife, and humans, a crucial factor in maintaining ecosystem balance. They are also biodegradable, leave minimal toxic residues, and have short pre-harvest intervals, aligning with the principles of organic farming and Integrated Pest Management (IPM) programs. While challenges like slower action, lower shelf life, and technical barriers to efficacy exist compared to some synthetic counterparts, ongoing research and new formulations (including nanotechnology) are improving their performance and market viability. Ultimately, the integration of biopesticides represents a critical and sustainable strategy for modern potato insect management, ensuring productivity while safeguarding environmental and human health.
