The other thing to consider is that this is 99.8% water. Are Marigolds Good for Companion Planting? Then thoroughly wash off the chemical by running water over the seeds for a minute.”.
“For plants with root rot or fungal infections, use 1 tablespoon hydrogen peroxide per cup of water”. It is water with an extra oxygen atom attached. To use, simply spray plants with undiluted 3 percent hydrogen peroxide that you can purchase almost anywhere.
Current science does not support this practice. The key here is to use controls.
“Mix some peroxide into your watering can before you take it out into the garden. the plants were sprayed after transplanting and before the disease started.

Hydrogen peroxide is technically water with an additional oxygen atom. By continuing you agree to the use of cookies. A lot of the commercial potting soil I see has mycorrhizal fungi added. A soak in hydrogen peroxide did not improve the germination of Kentucky bluegrass. Make sure to coat the leaves as well as spraying around the base of the plant to prevent the root-boring insects from damaging your crops. Some of the seed needs to be treated in a normal way to compare it to seed treated with peroxide. While some people are talking about disinfecting media, others are adding microbes to make plants grow better.
Use the same solution to help your seeds sprout faster and be less susceptible to insect damage. Experiments were carried out under greenhouse conditions aiming to evaluate phenotypical, biochemical and molecular features in these pepper plants. Hydrogen peroxide at 6, 14 and 18 mM induced tolerance to PepGMV either by absence of symptoms as well as by attenuating and/or delaying them. The peroxide releases oxygen and somehow this opens up the pores in soil. However: Powdery mildew seems to be a difficult fungus to cure once plants have it. Most of the claims made on gardening blogs and social media are not supported by science. Adult bugs do not like hydrogen peroxide. Many gardeners are always looking for methods to keep bugs off their plants. This kind of information is almost nonexistent. Also note this requires a higher concentration of peroxide than the normal consumer product and that inhaling this higher concentration is harmful to lungs. To keep bugs from infecting your garden plants, spray them once a week with the hydrogen peroxide mixture. You can keyword search: The Oxidative Burst in Plant Disease Resistance for detailed information. Pour the mixture into a spray bottle using a funnel if necessary. “You can use hydrogen peroxide to combat every kind of fungal infection on your plants.” One site recommends using a 0.75% solution for spraying plants, which is a 200 mM solution. Light will also degrade it, explaining why it is kept in brown plastic containers.
It is very reactive and easily loses the extra oxygen when it comes into contact with all kinds of other chemicals. If you spray an insect or eggs it is quite likely it will be harmed and might even be killed. As soon as water is absorbed, natural peroxide levels influence several of the key processes that need to happen before seeds germinate and higher levels can speed up the process. Robert I started a garden this year and your blog has been invaluable. Experimentation with seeds would be a good place for some citizen science work.
In low amounts it can trigger a plant to initiate the production of natural pesticides which in turn protect the plant from insects and diseases. PepGMV is a main phytopathogen in Mexican pepper crops. The blanket statements on the internet about speeding up all seed germination is false since most types of seed have not even been tested. Given the above mentioned phytotoxicity levels, this is quite possible but it would also kill non-weed plants.
The problem for the gardener is to know which cases work, when to spray and what concentration to use. Soak your media in peroxide and it will kill some of the microbes – but is this a good thing? Sanitizing seeds might have helped in some cases, but in general, seeds do not need to be sanitized. “A 1% hydrogen peroxide solution is safe to use and will keep away insects and kill any eggs.
Hydrogen peroxide is made by plants and used to control a number of internal hormonal systems.
Popular suggestions also ignore the potential harm these treatments can do.

Copyright Leaf Group Ltd. // Leaf Group Lifestyle. It is suggested to use a 3% soak for 30 minutes. Peroxide soaks can help with germination but the actual mechanism is complex and still being elicited by scientists. Stir and it is ready for a spray bottle. A hydrogen peroxide concentration of over 1% reduced the number of lettuce seed that germinated, but even at 0.1%, the length of the radical (root) was reduced in size. The problem being solved is, too much water in the soil. Some claim peroxide kills larvae and eggs of fungus gnats, but I could not find a reliable source that confirms this. “Raw or lightly cooked sprouts are a common source of foodborne illness.” Unlike the above recommendation, UC Davis suggests to, “treat the seed by heating on the stovetop for five minutes in a solution of 3% hydrogen peroxide preheated to 140°F (60°C).”. In wet conditions even sterilized seed will get damping off. Other claims include the following. In fact, an older method for measuring the amount of organic matter in soil used peroxide as the main reagent.
One concern with seedlings is damping off disease. It does not work for all seeds and too much can harm them.
Robert, thank you for your posting your clarification on H2O2. We’re is your scientific proof that some of these h202 methods don’t work. Many gardeners are always looking for methods to keep bugs off their plants.
Simply add 1 tablespoon of hydrogen peroxide to a gallon of water. Hydrogen peroxide contains no chemicals harmful to humans, pets or plants.
There is one case were seed sanitation may be a good idea and that is for growing sprouts (i.e. Peroxide will release oxygen, but it will not build up enough pressure to open up new pores in soil. Should Hydrogen Peroxide Be Used in the Garden? Do not proceed if there is any damage to plant tissue.
If you have a problem it might be worth your while to do some experimentation by applying different concentrations and seeing if there is an improvement in plants. Each chemical of concern should be researched and evaluated on its own merits.
Peroxide is sold in most pharmacies as a disinfectant in either a 3% or 6% solution, but is also available at higher concentrations.
Controlled elicitation using hydrogen peroxide in pepper is an alternative to protection against PepGMV infections. Pour the mixture into a spray bottle using a funnel if necessary. The present work examined the effect of exogenous application of hydrogen peroxide (H2O2) on inducing resistance to PepGMV infection in pepper plants. The claim goes something like this.
Plants don’t grow well in compacted soil and it is claimed that pouring peroxide onto it will reduce compaction.
