Powdery Mildew Prevention and Control
Prevention and Control of Powdery Mildew is a very important thing to consider. If you ever see a flour-like substance on your plants that is more than likely what is called powdery mildew.
It is a fungus that infects a wide variety of plants such as squash, pumpkins, melons, tomatoes, roses, and beans.
There are certain plants that are resistant to this disease that you can incorporate to deter the fungus. These plants include, but are not limited to phlox, bee-balm, and zinnias.
Once the fungus begins to take over one of your plants you will see a layer of white mildew. This is made up of many spores causing the white film. They travel from plant to plant by the wind.
There are many ways to control and prevent powdery mildew.
Consider spraying the infected plants with protectant fungicides, if you do not want to use a chemical fungicide try spraying your plants with a bicarbonate solution.
Mix one teaspoon of baking soda with one quart of water and spray your plants thoroughly, this solution will only kill fungus that it meets.
Selectively pruning the plants so they are not overcrowded is a good way to help reduce humidity and reduce the chances of the disease spreading.
Also try to keep these plant varieties in sunnier spots as the fungus prefers shady areas.
If you have plants that are already infected, it may be difficult to get rid of the disease.
Consider removing the infested foliage, stems, and fruit and destroy them.
Do not compost them as they may still be able to spread the disease. Controlling and preventing fungal diseases in plants should be a top priority!
