Sodium carbonate peroxyhydrate, the active ingredient in PerCarb, is a combination of sodium carbonate infused with hydrogen peroxide (H2O2). The active ingredient, upon activating with water, releases H2O2 which oxidizes pathogen cell structures upon contact resulting in significant surface and intracellular damage resulting in cell death of pathogens. The residual Sodium Carbonate plays a preventative role by inhibiting the development of fungal mycelium and spores through changes in pH and osmotic pressure of the target pathogen cells.
Foliar Spray Program
USE FOLIAR SPRAY APPLICATIONS THROUGHOUT THE GROWING SEASON ON LABELED CROPS. PREPARE SOLUTION BY MIXING 0.25–0.75 LBS. (4–12 OZ.) OF PERCARB/25 GALLONS OF WATER (1–3 LBS./100 GALLONS OF WATER). USE UP TO 400 GALLONS OF SPRAY SOLUTION/ACRE.
FOR THE MOST EFFECTIVE RESULTS, USE ENOUGH VOLUME OF SPRAY SOLUTION TO OBTAIN COMPLETE AND UNIFORM COVERAGE OF FOLIAGE AND STEMS. REPEAT SPRAYS AT 7–10 DAY INTERVALS DURING PEAK DISEASE PRESSURE.
