A plant disease is defined as “anything that prevents a plant from performing to its maximum potential.” This definition is broad and includes abiotic and biotic plant diseases.
How do you identify plant diseases?
Diseased plants can be identified by abnormal growth or by signs of the disease-causing organism, such as bacterial slime (an external sign of a disease called bacterial wet wood) or insect larvae which hatches from eggs and feeds on leaves.
How will you detect and diagnose the plant disease?
Laboratory-based techniques such as polymerase chain reaction (PCR), immunofluorescence (IF), fluorescence in-situ hybridization (FISH), enzyme-linked immunosorbent assay (ELISA), flow cytometry (FCM) and gas chromatography-mass spectrometry (GC-MS) are some of the direct detection methods.
How do you kill bacteria on plants?
The best way to treat suspected bacterial infections is to cut out all infected plant parts in order to prevent further spread. You can also use a bactericide in the early stages of the disease. Certain bacterial infections (such as wilts) can be transmitted by insects as they bite and feed on plant tissue.

What is a plant disease and what are the causes?
Abstract. Infectious plant diseases are caused by living (biotic) agents, or pathogens. These pathogens can be spread from an infected plant or plant debris to a healthy plant. Microorganisms that cause plant diseases include nematodes, fungi, bacteria, and mycoplasmas.
What does fungus look like on plants?
Fungi thrive on the energy from the plants on which they live. … Different types of fungi have a variety of appearances that include wilting, scabs, moldy coatings, blotches, or rotted plant tissue. Some come through the air via spores and attach onto the plant’s leaves.
How do you kill plant diseases?
A variety of chemicals are available that have been designed to control plant diseases by inhibiting the growth of or by killing the disease-causing pathogens. Chemicals used to control bacteria (bactericides), fungi (fungicides), and nematodes (nematicides) may be applied to seeds, foliage, flowers, fruit, or soil.
What are the symptoms of bacterial disease in plants?
Symptoms of bacterial infection in plants are much like the symptoms in fungal plant disease. They include leaf spots, blights, wilts, scabs, cankers and soft rots of roots, storage organs and fruit, and overgrowth. Bacterial spots: the most common symptom of bacterial disease is leaf spots.
Which plant disease is caused by fungus?
Some fungal diseases occur on a wide range of vegetables. These diseases include Anthracnose; Botrytis rots; Downy mildews; Fusarium rots; Powdery mildews; Rusts; Rhizoctonia rots; Sclerotinia rots; Sclerotium rots.
What is the importance of plant disease?
Importance of Plant Diseases The study of plant diseases is important as they cause loss to the plant as well as plant produce. The various types of losses occur in the field, in storage or any time between sowing and consumption of produce. The diseases are responsible for direct monitory loss and material loss.

Can you get diseases from plants?
Plant pathogens are very similar to those that cause disease in humans and animals. The pathogens responsible for causing most biotic plant diseases include viruses, bacteria and phytoplasmas, fungi and fungal-like organisms, nematodes and parasitic higher plants.
