It is important to know about the 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 go to waste because of insects, pests or plant diseases.
Plants get affected with diseases when they are weak and unhealthy. Several factors that can make plants more prone to diseases could be wet or humid conditions that are ideal for bacteria, fungi and viruses to grow. Humidity leads to the growth of moulds, 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 mostly due to high humidity and cool temperature.
Root and Stem Rot- If you over water the plants the roots and stem can start to rot. Growth of fungi leads to the rotting of roots and it can spread to the entire plant.
Blight- Tomatoesand potatoes are most commonly affected by blight. In this disease, the leaves get spots and gradually it leads to fruit rot and stem lesion.
Damping Off- In theearly 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 which causes spots and blotches on the leaves. It is a fungal disease and can affect many varieties 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 in the market for the treatment of plant diseases.
