Make your own preventative spray for powdery mildew. Pharmaceutical grade (3%) hydrogen peroxide diluted down to the 0.5-1% (5000/10000ppm) level makes an organic remedy useful as a natural fungicide for powdery mildew. You can apply it to the soil and or spray a fine mist on plant leaf surfaces for effective control. Powdery mildew is often associated with high humidity. If you are growing plants hydroponically, try adding the H2O2 directly to the hydroponic nutrient solution.
All Indigo® hydrogen peroxide test strips come with a 3 year minimum guaranteed shelf life with full documentation including Certificate of Analysis, Stability & SDS; Certificate of Conformance on request. Be prepared for any health & safety audit or inspection. See Documentation below.
Much stronger peroxide solutions (10%) kill mold spores on hard surfaces such as greenhouse walls. For this application, use Indigo® 10% H2O2 test strips to confirm correct dilutions of food grade concentrates down to the required ppm level.
