Handle Diseases

A disease is an interruption or disorder of a body or system. Just as with humans, the best way to avoid  diseases is to stay healthy. Diseases occur most often in weakened plants. Yet everybody gets sick sometime. Most diseases will pass automatically with time, but some are structural and can become be fatal.
When diseases become structural, replace the plants with another species. make sure your yard is healthy, soil quality, ventilation, sun hours and humidity are important factors for diseases, so make sure your plants are suitable for the local climate and their location.

Virus Infection

Bacterial Infection

Fungal Disease


Blight Investation


Plant viruses are generally transmitted from plant to plant, through air or by insects. The viruses cause various types of plant diseases, but the diseases do not typically result in plant death. They do however, produce symptoms such as ringspots, mosaic pattern development, leaf yellowing and distortion, as well as deformed growth. . Some plant viruses are not limited to one particular plant host, but may infect different varieties of plants. Currently, there is no cure for these viral diseases. If you want to avoid virus damaged plants, your infected plants must be removed and destroyed.

Bacteria and Protozoa

Bacteria and Protozoa are tiny cellular organism that can create symbiotic relationships with plants. Only a small number cause disease, but most are beneficial for the soil and the plants. Bacteria can also be used as organic pesticides; Milky spore is responsible for a disease of the white grubs and can be used in lawn care.


Nematodes are small, multicellular wormlike animals. Many live freely in the soil, but there are some species that parasitize plant roots. Just like bacteria, nematodes can be beneficial or damaging. Nematodes are common on the roots of legume plants and help transforming the nitrogen in the air into a form of nitrogen that can be used in the soil for fertilization. Nematodes are also used as a natural pesticide for lawn grubs.


Fungi reproduce via spores. Spores may be spread long distances by air or water, or they may be soilborne. The fungus may appear on the foliage, near the base of the plant, in the soil or on the fruit and flowers of the plant. Though some fungi can be beneficial or just create some cosmetic hassle, other fungal outbreaks can cause permanent injury and even death of the plant. Plants, often already weakened plants, that are infected with fungal diseases may develop cankers, lesions and rot. Some rot diseases are curable with fungicidal treatments, others are irreversible.


Blight is not a disease but a symptom. It is a rapid and complete decoloration, browning, then death of plant tissues such as leaves, branches, twigs, or floral organs Many diseases caused by viruses, bacteria or fungi  exhibit this symptom and are called blights.
