If you see white stuff on your African violets, it is probably powdery mildew. This is a common fungal disease that can be controlled with a fungicide.

How do you get rid of white fungus on African violets?

There are two main methods of controlling fungal diseases in African violets – using laundry bleach or bicarbonate soda. Both of these methods work by killing the fungus spores, preventing them from infecting the plants.

To use laundry bleach, mix one teaspoon of bleach with one litre of water and spray the solution onto the affected leaves. This will kill the fungus spores and prevent them from causing further damage to the plants.

To use bicarbonate soda, mix one teaspoon of soda with one litre of warm water and spray the solution onto the affected leaves. This will change the pH of the leaf surface, making it uninhabitable for the fungus.

There are a few effective organic fungicides for treating powdery mildew, which include sulfur, lime-sulfur, neem oil, and potassium bicarbonate. These are most effective when used prior to infection or when you first see signs of the disease. Baking soda has also been proved by many gardeners to be effective in treating powdery mildew.

Does overwatering cause powdery mildew

Powdery mildew is a type of fungal growth that can occur on leaves and stems in high humidity or overwatered conditions. The fungus produces a white or gray powdery growth on the surface of the plant tissue. Powdery mildew can weaken the plant and cause it to produce abnormally small leaves. In severe cases, the plant may be killed.

Powdery mildew is a fungal disease that affects many different types of plants. It is characterized by a powdery gray or white coating on the leaves and stems of infected plants. Powdery mildew typically starts out as a few spores on the leaves, and quickly spreads, eventually yellowing the leaves and causing premature leaf drop.

If you see white stuff on your African violet leaves, it is probably powdery mildew. This is a common problem with African violets, but there are a few things you can do to prevent it.

First, make sure your African violet is getting enough light. Powdery mildew thrives in humid, dark environments, so if your plant is in a low-light area, it may be more susceptible to the fungus.

second, water your African violet from the bottom, not the top. Watering from the bottom will help to prevent the leaves from getting wet, which can create a more favorable environment for powdery mildew to grow.

Third, keep your African violet pot clean. Remove any dead leaves or other debris from the pot on a regular basis, and disinfect the pot with a diluted bleach solution every few months.

fourth, consider using a fungicide to prevent powdery mildew. There are a number of products on the market that are specifically designed to combat the fungus.

By following these tips, you can help to prevent powdery mildew from growing on your African violet leaves.

If you have white stuff on your African violets, it is probably powdery mildew. You can get rid of it by mixing one tablespoon of baking soda with two and a half tablespoons of horticultural oil in a gallon of water. Spray your plants with this solution once a week for three weeks.
