Root rot is a common disease that can affect many different plants. If you’re wondering what the best fungicide for root rot is, we have you covered. We’ll cover how to treat root rot in general and then give you some specific recommendations on what fungicides are effective against it.

Root rot is caused by a fungus called Phytophthora. It’s typically found in areas with heavy rainfall or poorly drained soil, but it can also be found in areas with stagnant water or where irrigation drains back into the soil. The fungus attacks the roots of plants, which weakens them and eventually causes them to die off entirely. Root rot can be very destructive because it often attacks entire fields at once; this means that entire crops may die off even though there are no visible signs of damage on the surface of the soil or plants themselves.

Fungicides are only effective for stopping the spread of fungi. They do not treat the root rot itself. If there is no way to remove the infected plant, then you may have to resort to treating it with a fungicide to prevent it from spreading to other plants.

Best Fungicide For Root Rot

Many gardeners swear by cinnamon to control root rot. Interestingly, this natural fungicide has relatively low toxicity and has been found effective against more than 40 varieties of crops. The active ingredient in cinnamon is cinnamaldehyde, so it has minimal side effects. Read on to learn more about cinnamon’s effectiveness and what other natural products you should try to protect your garden from root rot.

Phytophthora root rot

Phytophthora root rot is a fungal disease that infests many ornamental trees. This disease develops root and crown rot in trees. Trees with this disease often show early signs of the disease by losing their leaves. They may appear brown and orange, and they may smell decayed. Symptoms of this disease can be difficult to detect, so be sure to identify your trees’ particular symptoms.

Phytophthora root rot is more difficult to control than Rhizoctonia or Pythium. Depending on the species of the disease, it may spread from one crop to another, including prefinished plants and used flats. It may also be spread by soil-borne pathogens. If you suspect that your plants are infected, consult with a nursery or a farm advisor.

Prevention is key when it comes to protecting your trees. Phytophthora species are spread by splashing rain, irrigation, runoff water, and contaminated garden equipment. Plants in moist, cool climates are more susceptible to fungus. Low rainfall, flooded soil, and soil that has been saturated is also conducive to the spread of this disease. Fortunately, fungicides have become an effective tool against Phytophthora root rot.

Fortunately, new fungicides are emerging. In addition to a range of phenyl amide fungicides, these agents have proven effective in controlling the disease. For more than 10 years, RIDOMIL GOLD 480 EC has been the standard fungicide for the control of Phytophthora on raspberries and snapdragons. Recent failures of this fungicide have likely been due to increased resistance among the pathogen and the fungi used to control this disease.

Orkestra Intrinsic

Orkestra Intrinsic fungicidal granules are a fungicide that is used as a preventive control for certain soilborne plant diseases, including Fusaria spp., root rot, and crown rot. They should be applied to well-drained substrates between seven and 28 days before the first signs of root rot appear.

The Orkestra Intrinsic branded fungicide is a dual-mode fungicide that offers both early and residual protection against key plant diseases. Its dual-action mechanism prevents the growth of fungal cells and improves photosynthetic efficiency, resulting in stronger and more disease-free plants. It is registered in California. While other products are based on a single active ingredient, Orkestra Intrinsic fungicide is registered for use in ornamental plants.

In one study, some fungicides provided effective control of Phytophthora root rot on dogwood seedlings. Preventive application of Subdue MAXX (a fungicide) consistently inhibited the growth of P. cinnamomi in all flood durations. By contrast, nontreated and inoculated control plants consistently displayed signs of root rot disease. The longer the flooding time, the greater the disease pressure on the plants.

Preventive treatment of trees with Orkestra Intrinsic, Empress Intrinsic, and Tartan Stressgard significantly reduced disease pressure. Preventive application of these products reduced the disease pressure and the number of ambrosia beetle attacks. The efficacy of the Orkestra Intrinsic fungicide was also evaluated in a further study on tree fungi.

Another study conducted on Prosodic used a fungicide formulated by Helena Chemical Company and an antibiotic named Subdue MAXX to control plant rot. The fungicide treatment was performed in a one-time application as directed on the label. It is available in 2.5-gallon jugs and 250-gallon totes. Prosodic is available in many forms, including sprays, granules, and sterile water for plant growth.


If you’re looking for a fungicide for root rot, the best choice is likely phosphatacid. This chemical is effective against a variety of fungi, including the common potato tuber rots. Interestingly enough, phosphatacid is also effective against some other diseases, including crown rot and downy mildew. It has also been shown to be effective against the pathogen responsible for sudden oak death.

When applying fungicide, always remember to read the label on the product. For example, ammonium sulfate, which is a type of quick-release soluble nitrogen, should only be used in small amounts. However, in the case of St. Augustinegrass and Bermudagrass, you should never use more than four or five pounds of nitrogen per thousand square feet per application. In addition to following the label instructions, you must also wear safety gear. To make the process as safe as possible, consult compatibility charts and/or with your Extension agent. Keep in mind that fungicides must not be mixed.

Fosetyl-Al, a systemic fungicide, is registered by the EPA in 1983. This fungicide controls root rot and damping-off of plant roots. In addition, fetal-Al is taken up by plants, where it ionizes to phosphonate. It is not effective against fungi that infect ornamental plants.

Besides fungicidal activity, phosphorus acid is also an effective agrochemical. It has an advantage over phosphorous sulfate, a synthetic fertilizer with low nutritional value. Phosphoric acid is effective against a variety of die-back diseases caused by Oomycota and is available in a variety of different products. It is a safe, non-scheduled fungicide.

Hydrogen peroxide

You can use hydrogen peroxide to treat your garden in several ways. It can be applied directly to the roots of the plants, as well as to gnats and other pests. Hydrogen peroxide can also be used as a preventative measure if your plants are suffering from root rot. To use hydrogen peroxide as a preventative measure, simply soak your seeds in the mixture for eight to 24 hours. Afterward, just spray the mixture on a paper towel before you plant your seeds. Not only will this help your plants grow healthy and strong, but it can also help protect them from the harmful effects of overwatering.

Hydrogen peroxide is an excellent fungicide for root rot, as it kills bacteria that cause the rot. When applied to infected plants, a solution of 3% hydrogen peroxide in distilled water is enough to cure root rot. Hydrogen peroxide will also help disinfect the soil and potting mix. When applied to the roots, this solution will boost the oxygen level in the soil, which helps the plants absorb nutrients.

Hydrogen peroxide is also helpful for cleaning and disinfecting small wounds. While it can be harmful to plants in large quantities, hydrogen peroxide as a fungicide is safe to use on plants. Its use is recognized by the United States Environmental Protection Agency (EPA).

Hydrogen peroxide is also a general fertilizer. It promotes plant growth by encouraging healthy root development. As a result, your plants will grow quickly. In addition to its many benefits, hydrogen peroxide also discourages the growth of bacteria and fungus. Besides being a natural fertilizer, hydrogen peroxide helps your plants absorb nutrients more efficiently from the soil.

Baking soda

Baking soda is an organic fungicide, making it a natural option to combat plant diseases. The mixture contains one tbsp of baking soda with two-1/2 tbsp of vegetable oil and half a teaspoon of Castile soap. The solution is applied to plant leaves and soil surface, where it will work to destroy fungus and mildew. The solution should not be applied to the hot sun, which will burn the leaves of plants.

Although baking soda contains sodium, it can be toxic to plants. Using baking soda to prevent rot is safe for your Monstera, but it’s important to know that too much of it can harm your plants. You can use up to a cup of baking soda per gallon of water. You can also use apple cider vinegar to prevent fungal black root rot by mixing it with a gallon of water and spraying the leaves of your Monstera.

A fungicide can kill root rot quickly, and it’s cheap and easy to use. There are many types of fungicides available, both organic and synthetic, and can be found in most garden stores. The chemical-based products are not a permanent solution and should be used in conjunction with other methods to prevent further damage. This is a temporary solution to a serious problem and should not be relied on as a one-time solution.

If you notice discoloration in your plant’s roots or leaves, you may have black root rot. This disease kills plants and kills their foliage. It can also cause the entire plant to die. When the fungus spreads rapidly throughout a plant, it can kill off its spores and cause other problems. For this reason, potassium bicarbonate is a great alternative to copper and other harmful chemicals. It kills both the mature fungus as well as its spores.
