Restoring Citrus-Greening (HLB) Groves to Marketable Fruit
A field program with GreenAgri Solutions LLC in Springhill, Florida, using a JC 9465 foliar-and-soil protocol on HLB-diseased citrus.
The Problem
The Challenge
Citrus greening — Huanglongbing (HLB) — has devastated Florida citrus. Since 2019, more than 75% of the state's citrus has been lost, with orange production down about 75% and grapefruit down about 85%. The disease starves trees of nutrients, degrades fruit, and has had no reliable cure.
Jenfitch partnered with GreenAgri Solutions LLC (Springhill, Florida) to test whether its reactive-oxygen-species chemistry could restore diseased trees to productive, marketable fruit.
The Program
The Jenfitch Solution
The protocol combined a foliar spray with a light soil drench, applied in the early morning and held at a disinfecting oxidation-reduction potential. JC 9465 is effective against 99.99% of bacteria and viruses, and it began working almost immediately in the grove.
- 2% JC 9465 foliar spray plus a light soil drench, applied early morning.
- Every two weeks over a six-week window, holding ORP above +700 mV.
- Started on a single tree — which pushed a new healthy "flush" within a week — then expanded to 20 trees.
- After 60 days, all treated trees had developed marketable fruit.
The Data
The Results
| Stage | Outcome |
|---|---|
| Single tree, first application | New healthy flush within a week |
| Scaled trial | Expanded to 20 trees |
| After 60 days | All treated trees developed marketable fruit |
| Program today | Now in its 4th year across 2 acres (1 control, 1 treated) |
| Pathogen efficacy | Effective against 99.99% of bacteria and viruses |
From diseased to marketable in 60 days
A single treated tree produced a new healthy flush within a week; the trial scaled to 20 trees, and after 60 days all developed marketable fruit. The program is now in its fourth year across two acres — one control block, one treated.

Frequently Asked Questions
About this citrus-greening program.
What is citrus greening (HLB)?
Huanglongbing (HLB), or citrus greening, has destroyed the majority of Florida citrus — more than 75% lost since 2019, with oranges down about 75% and grapefruit about 85%. It starves trees and degrades fruit.
What was the treatment protocol?
A 2% JC 9465 foliar spray plus a light soil drench, applied early morning every two weeks over a six-week window while holding ORP above +700 mV, in partnership with GreenAgri Solutions LLC in Springhill, Florida.
How fast did trees respond?
A single treated tree pushed a new healthy flush within a week. The trial expanded to 20 trees, and after 60 days all had developed marketable fruit.
Is the program still running?
Yes. It is now in its fourth year across two acres — one control block and one treated block. JC 9465 is effective against 99.99% of bacteria and viruses.
