Field studies on crop yield, food safety, post-harvest disinfection, shelf-life, and pathogen control using JC 9465 reactive oxygen species technology.
Jenfitch agricultural research covers crop yield, post-harvest disinfection, shelf life, and plant-pathogen control using JC 9465 reactive oxygen species chemistry. A 2023 Sawtooth Ag Research vineyard study in Selma, California recorded 49% higher harvestable yield and 50% less sour rot on foliar treatment, and citrus-greening trees returned marketable fruit within 60 days.

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. That covers foliar and soil-irrigation applications in the field as well as packhouse and post-harvest disinfection work. JC 9465 and JC 9450 are the same reactive oxygen species chemistry carried on two different registration paths, which is why the certifications differ between them.
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%. The trial ran on a six-year-old vineyard block in Selma, California, with four JC 9465 applications on April 26, May 18, June 16, and July 14. Foliar spray was applied at 390 mg/L and soil irrigation at 78 mg/L.
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. Because the oxidation happens at the surface and the reaction products are mineral oxides rather than persistent residues, treated produce can be handled through normal packhouse and post-harvest steps without picking up an off flavor.
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. The same JC 9465 reactive oxygen species chemistry inactivates 99.99% of bacteria and viruses. Because kill efficacy tracks oxidation-reduction potential, post-harvest systems are controlled to a target ORP rather than by concentration alone.
Applications
Using ORP between +650 mV and +750 mV, JC 9465 creates a disinfection barrier for field harvesting and post-harvest operations.
