Hydrogen peroxide - Great Tool for Many Jobs

Hydrogen peroxide is not just good for scrapes and cuts. It is part of the Sick Tree Treatment to cure oak wilt, rose rosette and various other diseases like powdery mildew on crape myrtles and early blight on tomatoes. A few years back our salt- water pool was full of mustard algae, rare algae reported to have come from Mount St. Helens. Apparently neither chlorine from toxic chemicals nor from salt will control this algae problem. My pool man and others in the business said that toxic chemistry products like copper sulfate and sodium bromide must be used. Well - not in my pool!

I asked about hydrogen peroxide. The answers were consistent no’s, - that peroxide was just an oxidizer and would do nothing. Well, I thought about the experts and the university web sites that say no to hydrogen peroxide for other diseases. They were wrong about that, why not this? My pool man agreed that we should give it a shot. I had some 30% peroxide product left around from a previous project, so I put 3 gallons of the concentrated hydrogen peroxide in the water. The label said to use one gallon of product per 5000 gallons of pool water. The only change at first was a foaming that showed up in the skimmer.

Within a few hours, all the algae were gone and the water was crystal clear - all with one application. It has not returned.

The peroxide also works on the string algae in our koi ponds. For this I use the grocery store 3% product at about ½ gallon per 1000 gallons of water.

You can also use the grocery or drug store 3% stuff for treatment of fire blight, curly top on tomatoes and other plant pathogens. If you chose the 3% product, use about 2 parts water and 1 part hydrogen peroxide in the mix. Or better still, for plant diseases, add it to Garrett Juice instead of using just water. Adding about 16 oz. of 3% hydrogen peroxide to 1 gallon of Garrett Juice (ready-to- spray mix) seems to work very well for controlling various plant diseases. Spraying straight 3% product will burn plants in hot weather and is a waste of money.

Whether using concentrated 30% product or grocery store 3% product, the spray coming out of the sprayer should be about 1% hydrogen peroxide or slightly less. It is amazing how well it works and there is no need for the toxic chemicals. Hydrogen peroxide is a chemical but just one atom different than water (H 2 O 2 vs H 2 O) and degrades very quickly to water and oxygen. It will even happen in the original bottles after being exposed to air, so always keep the caps on tight and use fresh material only – even for those personal cuts and scrapes.
