estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming an average 5% crop loss from Brassica black spot bacterial disease, this technology could enable a 2% loss avoidance through early and precise diagnosis. With an estimated annual domestic Brassica vegetable production value of ~$1.35B (AI est.), the potential economic impact is calculated as ~$1.35B
× 2% × 0.5 (target crop ratio) = ~$13.5M/year (AI est.). This could contribute to stabilizing farmer profitability.

Speed to Market
6× faster than in-house development
This technology is based on established PCR techniques for primer set design and usage, with fundamental algorithms and protocols already proven. The patent document provides detailed primer sequences and examples, eliminating the need for licensees to conduct research and development from scratch.
