Ozone and heat treatment protocol for Pythium control in corn seeds
A novel protocol combining ozone and heat treatments to control Pythium in corn seeds. This method optimizes ozonated water immersion followed by hot water treatment, aiming to sanitize seeds, enhance germination, and improve crop growth.
Overview
This innovative protocol aims to control Pythium, a pathogen affecting corn seeds, through a combined treatment of ozone and heat. By submerging corn seeds in ozonated water followed by hot water treatment, this approach seeks to sanitize seeds effectively, reducing infection rates and potentially enhancing germination and crop yield.
Technical specifications
- Ozonated water treatment: Corn seeds are submerged in water infused with ozone to target and reduce Pythium pathogens.
- Hot water treatment: Following the ozone treatment, seeds undergo a hot water immersion to further sanitize and eliminate pathogens.
- Optimization: The protocol is being optimized for timing, dosage, and sequence to maximize seed health and growth outcomes.
Technology readiness level
The protocol is currently at TRL 4, having shown promise in prior studies with other seed species. Laboratory experiments and field trials are planned to further validate its efficacy for corn seeds and optimize treatment conditions.
