Field study — wine grapes
Sawtooth Ag Research (Steven Deitz) ran a 2023 field study on a mature six-year-old French Colombard vineyard in Selma, California. JC 9465 was applied four times — April 26, May 18, June 16 and July 14 — via both soil irrigation (78 mg/L) and foliar spray (390 mg/L).
Vineyard results
| Measure | Control | Treated (foliar) |
|---|---|---|
| Clusters per vine | 60 | 73 |
| Harvestable yield | Baseline | +49% |
| Sour rot | Baseline | −50% |
| Foliar dose | — | 390 mg/L |
| Soil-irrigation dose | — | 78 mg/L |
Citrus greening (HLB)
Since 2019, huanglongbing (citrus greening) has destroyed more than 75% of Florida citrus — roughly 75% of oranges and 85% of grapefruit. Working with GreenAgri Solutions LLC of Springhill, Florida, Jenfitch applied a 2% JC 9465 foliar spray plus a light soil drench early each morning, every two weeks over six weeks (three applications) at an ORP above +700 mV.
Emerging plant-disease work
Xylella clogs olive xylem by building a protective biofilm. The hydroxyl radicals generated by JC 9465 break down the biofilm's EPS matrix, then oxidize the bacterial DNA. Results have been positive and PCR-based trials are expanding.
Bakanae disease (Fusarium fujikuroi) typically causes around 30% yield loss in Southeast Asian rice. In Jenfitch trials, loss was reduced to below 10%.
Food safety
In UC Davis Post-Harvest testing, JC 9465 delivered a 6-log CFU reduction in under 10 seconds against E. coli, Listeria and Salmonella when held at +700 mV ORP. University of Washington work showed it eliminates cross-contamination during apple harvesting — a critical control point for post-harvest wash and hydro-cooler operations.
Across trials, crop-yield gains have ranged from 30% to 60%. The technology is also in use beyond row crops: aquaculture programs in Norway and Louisiana, and Canadian dairy hoof-disease studies. Because it works by oxidation rather than a persistent chemical residue, it extends shelf life without changing taste.
Held between +650 mV and +750 mV, JC 9465 creates a food-safety disinfection barrier for field harvesting, wash lines, hydro-coolers and ice — inactivating spoilage organisms as ROS-treated ice melts.
Questions
Yes. JC 9465 is EPA FIFRA registered (2020) and USDA NOP organic certified (2021, 7 CFR Part 205), so it can be used in certified-organic growing and post-harvest operations.
In the 2023 Sawtooth Ag Research study on mature French Colombard, the foliar treatment increased harvestable yield by 49%, raised clusters per vine from 60 to 73, and cut sour rot by 50%.
No. The chemistry works by generating reactive oxygen species that oxidize on contact and then revert to mild mineral-oxide by-products below FDA limits. It extends shelf life without altering taste.
At +700 mV it produced a 6-log reduction in under 10 seconds against E. coli, Listeria and Salmonella in UC Davis testing, and eliminated cross-contamination in University of Washington apple-harvest work.
Applications
Using ORP between +650 mV and +750 mV, JC 9465 creates a disinfection barrier for field harvesting and post-harvest operations.
