Plants can get diseases, too. If you are regularly observing your plants and you notice that they are beginning to look odd, chances are that these plants of yours are already infected by plant diseases.
Now, you have to act fast because you know that plant diseases could spread to all the other neighboring plants. But sadly, you don’t know what to do. That could be the worst scenario, right?
Today, we are going to learn all about the common plant diseases and what to do when you encounter them. Read on and discover a lot about these pesky diseases.
What are plant diseases?
Plant diseases are typically caused by fungi. Some other causes include bacterial and viral infections. These are some of the most common plant diseases.
Cankers are characterized by dead areas on a plant’s stem that turn to be discolored. They usually form on woody stems, and can be sunken areas, cracks or raised areas of abnormal or dead tissue. They may ooze or girdle trunks or shoots, which can cause everything to die.
Types of cankers are cytospora and nectria cankers.
There are a few types of blight to watch for. All of which are easily identifiable as they all cause the sudden death of all plant tissues such as the flowers, stems and leaves.
Fire blight is a bacterial disease that affects fruit trees, roses, and other small fruits. Shoots will look blackened once they get affected. You may notice lesions on the branches and limbs that secretes an amberish-brown liquid on very warm days.
Fungal blight can infect plants, vegetables, shade trees and fruit trees, but when it strikes tomatoes, peppers or potatoes, it’s called as early blight. Symptoms include brown to black colored spots on leaves which develop concentric rings. When heavily blighted, the leaves dry up and die as the spots grow together. The symptoms are noticeable on the lower leaves first.
Late blight can infect certain flowers causing dieback of shoots and stem cankers. It can also common in tomatoes, potatoes, and peppers. The early symptoms include water-soaked spots on lower leaves, which widen gradually and are mirrored beneath the leaf with a white soft growth. You may see dark-colored blotches penetrate the flesh on potatoes appearing as sunken lesions. The affected plant is about to rot and die during wet season.
This is not the ones you see on metal. Rusts are another type of fungal disease. Two different plant species may be needed by these to use as hosts in order to complete their life cycle. The usual symptom is a light brown to rust-hued coating, that often appears first on small branches.
These are just a few of the common kinds of plant diseases. Discover more about the others in the part 2 following this post.
