Protect your plants from Common Plant Diseases by learning to identify the symptoms and practice prevention. Firstly, you have to identify the correct symptoms of your plant disease. Then you should start a safe treatment for that specific disease. Are you a home gardener, or a farmer who grows plants & crops seasonally? Whoever you’re, you’ll surely need the basic information regarding plant Diseases and Treatment. Also, bookmark the page for later identification or treatment information.
Plant Disease
A Plant Disease is an impairment of the normal state of a plant that interrupts or modifies its normal & vital functions. All plant species, either wild or cultivated, are subject to disease. Although each species has specific diseases according to the environmental conditions as well as nutrient supplies deficiencies.
List of Common Plant Diseases
The Common Plant Diseases list has been prepared by me after completing research on the given plants. During my bachelor’s, I read a special course on Plant Pathology, Importance, Classification, and Treatment of the Major & Common Plant Diseases.

Common Plant Diseases
Let’s read out some of the Common Plant Diseases and preventive measures to reduce the chances of these diseases.
Chlorosis
Chlorosis is the yellowing of green leaves due to lack of photosynthetic pigment, chlorophyll. Chlorosis can be produced due nutrient deficiencies related to soil alkalinity (high pH), drought conditions, poor drainage, and compaction of the soil. It’s one of the very Common Plant Diseases.
Powdery Mildew
Powdery Mildew is a fungal disease that affects many of the landscape plants, flowers, vegetables, and fruits. You can easily identify this plant disease. Infected plants will have a white powdery substance on upper leaf surfaces, or anywhere like stems, flower buds, and even the fruit of the plant.
Black Spot
Black Spot is commonly caused by species of Pseudomonas bacteria or by fungus species in the genera Asterina, and Asterionella etc. This infectious disease is produced during damp periods and round to irregular black spots are developed on leaves, petioles, stems, and flowers of the plants. Black Spot of roses is a widespread disease caused by the fungus Diplocarpon rosae.
Downy Mildew
Downy Mildew is caused by algae. In Downy Mildew, grayish fuzzy-like spores are produced on the lower surfaces of leaves. Pale green or yellow spots may also be produced on the upper surfaces of older leaves. While on the lower surfaces of leaves, a white to greyish, cotton-like downy substance is developed.
Citrus Canker
Citrus Canker is often caused by fungal or bacterial pathogens. Some cankers are not serious while others can be lethal. Common symptoms of Citrus Canker are sunken, swollen, cracked or dead tissue found on stems, limbs or trunk.
Potato Blight
Potato Blight is a common disease in Potatoes but can also affect other plants such as tomatoes. Do you remember the potato famine in the 1840’s? In 1840’s, as a result of the Potato Blight, one million people died due to hunger famine. It is commonly a fungal disease which spreads through spores. These spores spread widely and reached faraway areas.
Anthracnose
Anthracnose is a fungus that infects many deciduous and evergreen trees & shrubs, as well as fruits, vegetables, and grass. Very small lesions are developed along the leaves and the veins. These dark, sunken lesions may also be found on stems, flowers, and fruits of the deciduous and evergreen plants.
Apple Scab
Apple scab is a common disease of plants in the rose family (Rosaceae) that is caused by the ascomycete fungus. The symptoms of the Apple Scab disease are found in the foliage, blossoms, and developing fruits of affected trees, which turned dark, irregular in shape after lesions production.
