Abiotic diseases are the result of the interaction, over an extended period of time, between the plant and one or more factors such as lack of space for root growth, the presence of chronic or acute levels of air or water pollutants, or the presence of extremes of moisture, heat, light, soil pH, and nutrients.
What are abiotic diseases in plants?
For the purposes of this article we will refer to them as abiotic disorders. Unfavorable soil properties, fertility imbalances, moisture extremes, temperature extremes, chemical toxicity, physical injuries, and other problems are examples of abiotic disorders that can reduce plant health and even kill plants.
Which one is the abiotic causes of disease?
Hot weather, inadequate moisture, drifting of herbicides, freezing temperatures, transplant shock, compacted soils, mower injury, and lack of nutrients are examples of factors that can cause abiotic disease problems.
What are the biotic and abiotic causes of plant disease?
Biotic (infectious) diseases are developed owing to microbial infection, while abiotic (noninfectious) diseases are developed due to environmental factors. In this chapter, we are concerned with plant pathogens or phytopathogenic microbes such as bacteria, viruses, fungi, mollicutes, and so on.
How are diseases caused in plants?
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.
How biotic factors that causes plant disease?
The infectious causes are classified as biotic (living) causes of plant problems. They include (but are not limited to) insects, mites, and disease pathogens. Environmental stresses, such as temperature injury and water or nutrient stress, are abiotic (nonliving) factors that may affect plant health.
How do plants treat abiotic disease?
How to Treat Abiotic Disorders
- Testing soil and fertilizing accordingly.
- Collecting and testing samples to identify and treat pests or diseases.
- Aerating compacted soil with an air tool to “fluff” it without damaging roots.
- Pruning to help a tree recover from damage caused by storms, road salt, or extreme temperatures.
Are plants biotic or abiotic?
Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.
How do abiotic factors help disease occurrence?
Abiotic events such as drought or over watering often stress plants and make them susceptible to secondary insect and disease organisms that would normally not cause a problem. Most infectious diseases are caused by fungi, bacteria and viruses. However, nematodes, and mycoplasmas also cause diseases.
What are the biotic pathogens of plant disease?
Fungi, fungal-like organisms, bacteria, phytoplasmas, viruses, viroids, nematodes and parasitic higher plants are all plant pathogens.
