What fungicide do you use for begonias?

When it comes to treating fungal infections in begonias, there are a few fungicides that are commonly used. Two effective options are myclobutanil and triadimefon. However, it is important to note that while triadimefon is highly effective, it can cause stunting in some plants, so it’s important to use it with caution.

Myclobutanil is a systemic fungicide that is known for its effectiveness against a wide range of fungal diseases, including those caused by Pythium spp. It works by inhibiting the growth of fungi and preventing them from spreading. When using myclobutanil, it is important to follow the instructions provided by the manufacturer, as each product may have specific guidelines for application.

Triadimefon, on the other hand, is also effective against Pythium spp., but it has been known to cause stunting in some plants. This means that while it can effectively treat the fungal infection, it may also negatively affect the growth and development of the begonias. It is recommended to test triadimefon on a small area of the plant before applying it to the entire plant to assess any potential stunting effects.

In my personal experience, I have used both myclobutanil and triadimefon to treat fungal infections in begonias. Myclobutanil has been effective in controlling the spread of the fungus and promoting the recovery of the plants. However, when using triadimefon, I have noticed some stunting in certain varieties of begonias. This is why I prefer to use myclobutanil as my go-to fungicide for begonias, as it provides effective control without the risk of stunting.

In addition to using fungicides, it is important to also take preventive measures to reduce the risk of fungal infections in begonias. This includes providing proper air circulation, avoiding overwatering, and keeping the foliage dry. Regularly inspecting the plants for any signs of infection and promptly removing any infected plant material can also help prevent the spread of fungal diseases.

When it comes to treating fungal infections in begonias, myclobutanil is a highly effective option. While triadimefon can also be effective, it may cause stunting in some plants. It is important to follow the instructions provided by the manufacturer and consider testing the product on a small area of the plant before applying it to the entire plant. Taking preventive measures and practicing good plant care can also help reduce the risk of fungal infections in begonias.
