Root rot occurs when the roots don't receive enough oxygen, usually because of too much water. A parasite called Pythium makes its way in, and needs to be sterilized from the soil! Use peroxide or bleach to do this!
Chemicals, such as chloropicrin or methyl bromide, won't completely cure the disease but can reduce the level of the infection. These fumigants are applied in and around the base of the infected trees or in holes left after trees have been removed.
Hydrogen peroxide can help to control fungal growth and fungal infection, such as root rot, by preventing the growth of fungi. It can also help kill fungus and bacteria on plant roots.
Yes, you can cut off rotten orchid roots with a sharp, sterilized tool; spray it with a 10 percent isopropyl alcohol solution between cuts. Remove roots at the base that have lost all firmness or turned dark. Roots that still show healthy color should be cut back to healthy tissue. Treat cuts with hydrogen peroxide.
Rubbing alcohol is best known for its efficiency in killing spider mites, aphids, and whiteflies. Make a spray solution of 1:8 ratio of rubbing alcohol and water. First, run a patch test on a small leaf. Once it passes the test, you can spray the plant, leave it on for 15-20 minutes, and rinse with water.
Hydrogen peroxide or bleach can be used to sterilize the soil and kill the fungus spores.
Apart from being more mindful of how often and how much water you give your plants and plant roots, you can also use a mixture of 3 percent hydrogen peroxide concentration mixed in 1 quart of water once a week to encourage healthy root growth in your plants' roots or treat the spread of root rot and root decay.
Another product that'll help prevent the spread of root rot is non-flavoured cinnamon. After having removed the dead roots, sprinkle a thin layer onto the healthy tissue before placing into a bed of new compost.
with either Daconil® Action™ fungicide (3.5 fl. oz./1,000 ft.2) or Secure® Action fungicide (0.5 fl. oz./1,000 ft.2) on a 14-day interval are most helpful when take-all root rot symptoms break through.
Dealing with Root Rot
Prepare plants for replanting by cleaning the roots gently under running water and removing all brown, mushy roots with a sharp pair of scissors. Cut the healthy root just above the damaged area. Work quickly to replant within a few hours.
If you use a higher concentration of hydrogen peroxide on the foliage of the plant you run the risk of burning it. You could burn the roots, but since it's necessary to kill the root rot-causing bacteria, it's a risk worth taking.
Cut off any diseased roots using a sterile cutting tool like a knife or scissors. You want to make sure that you're cutting off the roots that are black and mushy. After you've cut off any dead roots, we recommend soaking them in an 80:20 solution of water to hydrogen peroxide. Five minutes or so should be sufficient.
First option: Remove the plant from its pot.
Gently remove all the potting medium from around the roots of your plant. Once completely exposed, either spray or pour the hydrogen peroxide solution all over the root ball. Repot the plant in a new, damp potting mixture. Let the soil dry before watering the plant again.
Under aerobic soil metabolism conditions, hydrogen peroxide degrades with a half-life of ca. 1.4 hours in diluted test solutions. This half-life value was extrapolated to ca. 7 hours for concentrated test solutions.
Baking soda has a pH of around nine, and its alkalinity will act as poison for fungi. It will eliminate it from the roots by alkalizing the soil and preventing it from developing.
Personally, I use hydrogen peroxide more often than bleach. I mix hydrogen peroxide in my nutrient water to prevent root diseases such as root rot. While I use bleach only when cleaning my hydroponic system reservoir and gardening materials.
Dawn dish soap can save your plants from pest infestation, but it can damage them as well — this may sound contradictory, but it's true! Too much of it dissolved in water can burn the leaves of your sensitive plants. If you want to make this work, do these things: For a gallon of water, 1 teaspoon of it is fine.
Can Too Much Rubbing Alcohol Hurt the Plant? Yes, too much rubbing alcohol can hurt or kill a plant. It is best to apply rubbing alcohol as a spot treatment using a cotton swab or dilute the alcohol with water before applying it to the plant.
Double Up Your Protection with Isopropyl Alcohol
With the peroxide helping to keep your plants healthy and free of bacteria, you now need to prevent contamination of the tools and equipment you use to plant, trim, and water your crops.
