During 2023, Sawtooth Ag Research of Selma, CA tested JC 9465, a mineral oxychloride disinfectant, on wine grapes and cut sour rot in half while sharply increasing crop yield. Foliar application alone delivered a 50% drop in sour rot compared to the control and a 50% increase in crop yield.
The trial
The study was conducted on 6-year-old French Columbard wine grapes with a history of virus infections that emerged under seasonal stress. Four treatments were applied between April 26 and July 14, 2023.
Application schedule
- Soil irrigation: 78 mg/l concentration
- Foliar spray: 390 mg/l concentration, dosed at 0.05 oz/gal
The trial compared four groups: an untreated control, foliar spray only, soil irrigation only, and a combined foliar-plus-soil application.
Results
A 50% drop in sour rot compared to the control and a 50% increase in crop yield using JC 9465 through foliar application alone.
Yield improvements
- Foliar treatment produced 73 clusters per 2 vines, a 21.7% increase over the control's 60 clusters.
- Foliar spray produced 76 lbs per 2 vines, a 49.0% increase over the control's 51 lbs.
- The combined treatment achieved the maximum 50% sour rot reduction.
