Use the most effective fungicides (those with thiophanate-methyl, polyoxin-D, triflumizole or fludioxonil) preventively.
The benzimidazole fungicides such as thiophanate-methyl are very active against the fungus and are used as soil treatments to control it.
To make a safe hydrogen peroxide mixture, start by mixing 1 part hydrogen peroxide with 9 parts water. Next, soak the roots in the solution for 30 minutes. After 30 minutes, remove the roots from the solution and rinse them off with clean water.
However, some of the most common and effective fungicides include copper sulfate, hydrated lime, and baking soda.
"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.
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.
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.
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.
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.
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.
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!
Root rot is caused by numerous fungi, especially Armillaria mellea, Clitocybe tabescens, and Fusarium, and many oomycetes, including Pythium, Phytophthora, and Aphanomyces. Plants lose vigour, become stunted and yellow, and may wilt or die back and drop some leaves.
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.
Most root rot fungi prefer wet soil conditions and some, such as Pythium and Phytophthora, produce spores that can survive for long periods in soil.
For established plants: Mix 1:1 ratio of 3% H2O2 and water (eg: 1 cup of each). Bottom or top water as usual (water soil only, do not pour on leaves).
If you are treating a sick plant or one infested with insects, use a slightly stronger mixture of one tablespoon of hydrogen peroxide in eight ounces of water. Don't use hydrogen peroxide on your plants more frequently than twice each week. If you make more than you need, you can store it.
It is perfectly safe for plants when properly diluted and used in moderation. Adding hydrogen peroxide to water promotes better growth in plants and boosts roots ability to absorb nutrients from the soil. Diluted 3% peroxide adds needed aeration to the soil of plants and helps control fungus in the soil.
Best Overall
We chose the Lamisil Terbinafine Hydrochloride Antifungal Cream as our top pick because it works to address a variety of infections, including toenail fungus. The prescription-strength cream comes highly recommended by Dr. Lipner because it can treat athlete's foot before it spreads to the toenails.
What happens if you use too much fungicide or insecticide? Over-application of both fungicides and insecticides has the risk of damaging your grass and even killing it. It's worth knowing which specific type of grass you have so you can feel reassured your chosen pesticide is safe to use on your turf.
Lamisil comes in a spray and powder spray, in addition to the cream form. How it works: The most effective of all OTC treatments, according to the American Academy of Family Physicians, terbinafine is an antifungal product that kills the fungus and keeps it from coming back by inhibiting an enzyme it requires to grow.
