Plants are susceptible to diseases, and proper care must be given to them to grow gloriously.
It is essential to know about common plant diseases so that you can take appropriate action at the right time and save the plants from dying. No one would want their hard work to go to waste because of insects, pests, or plant diseases.
Plants get affected by diseases when they are weak and unhealthy. Several factors that can make plants more prone to diseases could be wet or humid conditions ideal for bacteria, fungi, and viruses to grow. Humidity leads to the growth of molds, mildew and algae on plants. Some of the common plant diseases are-
Powdery Mildew- Powdery Mildew can be identified as tiny white spots on the leaves that tend to spread, and ultimately the leaves turn yellow and die. It is caused mainly due to high humidity and cool temperature.
Root and Stem Rot- If you overwater the plants, the roots and stem can start to rot. The growth of fungi leads to the rotting of roots, which can spread to the entire plant.
Blight- Tomatoes and potatoes are most commonly affected by blight. In this disease, the leaves get spots, which gradually leads to fruit rot and stem lesion.
Damping Off- In the early stages, seedlings and young plants are prone to damping off. It occurs mainly due to over-watering, and the leaves start withering.
Rust- Rust is another common disease that causes spots and scars on the leaves. It is a fungal disease and can affect a wide variety of plants like Hollyhock, Roses, Fuchsias, Roses, and Chrysanthemums.
Some other diseases include Tobacco Mosaic Virus, Downy Mildew, Wilt disease, and Leaf Curl. Most of these diseases can be prevented if the plants are being grown in harmonious conditions and are getting ample nutrients, minerals, sunlight, and water to thrive. Several fungicides and other chemicals are available to treat plant diseases.
