To watch someone die would be the most unfortunate experience, and to be through the various stages leading to death will only augment the effect. One such living being that exists to blow oxygen into the beating heart of its owner is a plant. The green shade imparts a sense of unexpressed passion and infinite generosity.

Plant Disease

Every plant lives to extract the energy out of sunlight and produce flowers and fruits just to be plucked off later. But some other beings feed on these plants for survival, which gradually leads to their death. What you get is all the produce in abundance, and what do they get in return? Patches and pores all over their body.

To be stricken by disease and to live with it is quite excruciating. While we humans go in search of every possible cure, the plants that get affected are left out in the soil to be further distorted into nothingness. To care for these plants and to breathe back vitality into them are the duties of every human being. Most of the plants and trees get afflicted by diseases due to fungi, bacteria and viruses.

A few other diseases are called abiotic diseases, where the causes are non-infectious like that of air pollution, toxicities, and nutritional deficiencies. Please pay close attention to the plants and see whether they exhibit any symptoms or signs in the form of patches or any discolored surfaces.

If they do, make sure to take the necessary precautionary steps to control the spread of the pathogen, and find an appropriate cure. You can always seek help from various agencies for tree services to protect the plants and trees from being destroyed by the pathogens.

Signs and Symptoms of plant disease

Signs and symptoms are quite similar but are also different for their specific characteristics. When looking for a sign of plant disease, it should be the physical evidence of the pathogenic presence that should be noted. The symptoms of plant disease would be the visible effects such as discoloration and deformation of the plant structure. Most of the bacterial disease signs are not visible or observing it would be difficult. In the case of viral diseases, the viruses cannot be found on the leaf surface, and no signs will be exhibited.

The powdery mildew that is formed on lilac leaves is the fungal parasite (Microspaera alni) itself. Verticillium albo-atrum and V. dahliae are pathogens with a fungal nature that cause the wilting of leaves. The symptoms of a bacterial disease could include a bright yellow halo along the margin of a leaf, or on the interiors of leaves of the bean plant. Brown, necrotic lesions could also develop on the interiors or center portions of the leaves of other species.

Plant Disease Signs

What you see as signs would most probably be the pathogen itself, whereas the symptoms that have been mentioned are not pathogens, but they merely indicate the start of a disease. Following are a few common symptoms and signs of pathogenic plant diseases.

Signs

  • Fungal disease signs
  • The formation of rust on leaves (corn)
  • Rust on stems of plants such as wheat and rice
  • Powdery mildew
  • Bacterial disease signs
  • Oozing bacterial paste
  • Lesions that are soaked by water
  • The bacteria will exude in the form of water through a cut stem.

Plant Disease Symptoms

Symptoms

  • Fungal disease symptoms
  • Spots that resemble the shape of a bird’s eye starting to surface on berries.
  • Brown spots on leaves
  • The discoloration of leaves and their yellowing.
  • Bacterial disease symptoms
  • Cankers
  • Spots on fruits
  • Yellow halo on leaves
  • Viral disease symptoms
  • Leaves with a mosaic pattern
  • Extremely yellowed leaves
  • Stunting of plants and crinkling of leaves.

Common signs of tree disease

  • Holes left on the surface of leaves of trees and shrubs due to excessive insect attack
  • Infestation by mites can make the foliage yellow, dry and stippled
  • Presence of white spots on branches, leaves, and twigs
  • Tiny to huge holes on the barks of shrubs and trees
  • Black sticky liquids left on the surface of leaves by the insects.

Conclusion

All the greenery that surrounds us has life within them; they are equally subject to potential threats as well. For as long as the trees and plants stay immobile, it is the humans who have to feed them with the right nutrients and essential growth simulators. Also, make sure to check the plants and trees for signs of any diseases, and take the necessary steps to prevent their destruction.
