Comprehensive Defense without a Metabolic Tradeoff
Foundational plant health and season-long protection with just one application.
PreviSAR is a biological, mRNA-based foliar spray that primes a plant’s natural defenses to protect against disease.
Unlike traditional chemical treatments that require frequent applications, PreviSAR provides broad-spectrum protection with a single application. By activating the plant’s immune response, it defends against fungal, bacterial, and viral pathogens throughout the growing season, reducing the need for excessive chemical use and minimizing input costs. PreviSAR works by activating Systemic Acquired Resistance (SAR) — the plant’s own broad-spectrum, resistance-proof immunity — via a naturally occurring mRNA signal present in all plants.
Proven in the field: 39 peer-reviewed publications, 26 completed field trials with 14 more in the pipeline, and 100+ greenhouse trials across multiple U.S. states and 3 countries. In 2024, PreviSAR delivered a 43% disease reduction versus untreated crops — about 35% better than the leading biological — and over 90% control versus a conventional fungicide under low disease pressure.
Healthier plants require fewer chemicals and produce more marketable yield
Farmers today are under increasing financial strain as the costs of production continue to rise.
Traditional crop protection methods rely on frequent applications of chemical treatments, leading to higher input costs that also include equipment, labor and fuel. Additionally, repeated applications contribute to soil compaction, which can further impact crop health and productivity. As these challenges compound, farmers face mounting pressure to maintain profitability while protecting their crops from evolving threat of pathogens and disease.
