I spray my plants with Greencure (not sold anywhere now ) but it is Potassium Bicarbonate.. which can be bought in small amounts , I spray early in the AM once a week , works for me . I use approx 1 tbs per gallon in pump sprayer and coat top and bottoms of all the leaves and stems.

Food grade hydrogen peroxide?

Been like 12 years since I’ve used it but the plants loved it.

Used to get it from the health food store.

What are your mixing ratios. I have a similar product BioSafe ZeroTol HC. Used full strength and burnt the shit of the plants.
when in doubt , read the label..



APPLICATION RATES AND DIRECTIONS
Pre-Plant Dip Treatment
Use OxiDate 2.0 for the control of damping-off, root disease and stem rot disease caused by Pythium, Phytophthora, Rhizoctonia, Fusarium or Thielaviopsis, on seeds, seedlings, bulbs, or cuttings. Remove dead or dying foliage prior to dipping.

2. Immerse plants or cuttings; remove and allow to drain. Do not rinse. 3. Excessive foaming or bubbling during the dipping process is an indication
of high levels of disease contamination.
Seed Treatment
Use OxiDate 2.0 for the control of damping-off, root disease and stem rot disease caused by Pythium, Phytophthora, Rhizoctonia, Fusarium or Thielaviopsis, on seeds of seed sprout crops such as mung bean, red clover, soybeans and alfalfa, and on crops grown exclusively for seed for planting. 1. Use OxiDate 2.0 at a dilution rate of 1:100 (64 fl. oz. per 50 gallons

drain. Do not rinse. Plant seed according to seed package directions.
