What is the White Powdery Substance on My Plants?

Thursday, September 15


What is the white powdery substance on my plants? This probably is the most common problem for all gardeners. Almost all the plants and trees get affected by this disease which is known as Powdery Mildew. It can be identified by the appearance of white- grayish powder like substance on the leaves of plants or trees. It also results in stunted plant growth, distortion of buds and discoloration of leaves.

Powdery Mildew can pose as a serious threat to your plants and it can completely damage them. Powdery Mildew happens to be a fungal disease that is caused by many different species of fungi. If this disease is not controlled on time then it has the capacity to spread to other parts of the plants and even affect the surrounding plants. The affected leaves eventually turn yellow and die. This disease spreads and becomes severe in hot and dry climatic conditions. Plants that are growing in damp areas with poor air- circulation are more susceptible to powdery mildew.

Powdery Mildew can be prevented by growing disease resistant plants in your garden. There are several disease resistant varieties available in the market. If disease resistant variety for a particular plant is not available then it is advisable to plant them in sunny location where there is proper air circulation. You can also use organic or inorganic fungicides that are widely available to control the problem of powdery mildew. Get rid of the leaves that are infected with this disease so that it does not spread to the other parts. If you do not destroy the infected leaves then the disease can easily spread to the other plants.

By keeping all these things in mind you can control powdery mildew and avoid it from spreading. However, prevention is always better than cure so it is crucial to maintain healthy and hygienic conditions for plants to grow. Healthier plants are less prone to diseases so take good care of your plants…
