A good place to start is a mix of mild liquid soap and water, sprayed onto houseplants. One teaspoon of soap per litre of water will do the job. It sounds simple, but this formula will treat a lot of common houseplant pests. Add just a teaspoon of bicarbonate of soda and it becomes a great fungicide as well.
A fungicide for root rot is a chemical that kills the fungal pathogens that cause this condition. Fungicides come in both organic and synthetic forms, and they can be applied to the roots of plants to kill the fungus and prevent it from causing further damage.
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.
Turns out it can work wonders on a sick plant. The way it works is the chemical in hydrogen peroxide kills the bacteria that causes root rot in plants and breaks down into the soil to release extra oxygen to encourage the growth of healthy, new roots.
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.
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.
Hydrogen Peroxide Fungicide
To make a hydrogen peroxide fungicide, mix one tablespoon of hydrogen peroxide (3%) and one gallon of water. Shake the mixture well and spray it on the plants, making sure to cover both sides of the leaves. This recipe is particularly effective against root rot and damping-off.
Once root rot is identified, you must determine if the plant can be saved. If the entire root system has already become mushy, it is too late to save the plant. However, if some healthy, white, firm roots exist, try to bring the plant back to good health by replanting in fresh soil with good drainage.
It is not possible to reverse root rot. The treatment of this disease involves removing the affected portions of the plant. Once the rotting or dying parts have been removed, they can then be repotted in fresh soil to give the remaining healthy roots a fresh start.
Use cinnamon rooting hormone to encourage root development
Like sulphur, cinnamon is a natural fungicide that helps most plants root, while inhibiting the spores that cause rot in stem cuttings. Dip prepared plant stems in cinnamon and push them into the soil.
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.
Yes, coffee grounds can help prevent soil diseases… in a laboratory. Mixed into a growing mix, they have been found to control such harmful fungi as Pythium (which causes root rot) and Fusarium and Sclerotinia (vascular diseases).
Don't just pour straight hydrogen peroxide on the roots. Instead, create a mixture of one part 3% hydrogen peroxide and two parts water, and put it in a watering can or spray bottle. You can either use it while the plant is still in the pot, or after taking it out of the pot.
By strategically sprinkling cinnamon around the edge of containers and baskets, most pests will simply leave it alone and move on. Even with its strong smell, cinnamon will not cause any harm to the plants.
Baking soda (sodium bicarbonate) is an effective and inexpensive antifungal agent that is readily available at a supermarket. It is an organic and eco-friendly remedy for black spots and fungal diseases such as powdery mildew. Fungus can quickly damage plants and cause plants to wilt and die.
"Triazole fungicides are the most widely used fungicide class in the world," says Mueller. These locally systemic fungicides move up and down the plant but not in the leaf. Triazole fungicides (Folicur, Domark) inhibit an enzyme that plays a role in fungi sterol production.
Mix 50ml of Hydrogen Peroxide 3% – Oxygen PlusTM per 4 litres of water (60:1 ratio of water to H2O2). Soak the roots into this solution for about 6 hours. Replant in a new container with clean, fresh potting mix.
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.
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.
Hydrogen peroxide (H2O2) is steadily gaining more attention in the field of molecular biology research. It is a major REDOX (reduction–oxidation reaction) metabolite and at high concentrations induces oxidative damage to biomolecules, which can culminate in cell death.
