A plant generally develops a disease when it is persistently bothered by a causal agent that causes an abnormal physiological process that interferes with the plant's natural structure, growth, function, or other activities. The disruption of one or more of a plant's vital physiological or biochemical systems results in the occurrence of recognizable pathological diseases or symptoms[1]. Depending on whether their major cause is infectious or noninfectious, plant diseases can be widely categorized. An infectious pathogenic organism, such as a fungus, bacterium, mycoplasma, virus, viroid, nematode, or parasitic flowering plant, is what causes infectious plant illnesses. An infectious agent is capable of procreating both inside or on its host and spreading to additional hosts that are susceptible to it. Non-infectious plant illnesses are brought on by unfavorable growing conditions, such as temperature extremes, unfavorable oxygen-moisture ratios, noxious materials in the soil or atmosphere, and an abundance or shortage of a vital mineral[2].Noninfectious causal agents are not transmissible since they are not living things that can reproduce inside of a host. In the natural world, multiple disease-causing agents may be affecting plants at once. A plant is frequently more vulnerable to infection by a pathogen when it must deal with nutrient deprivation or an imbalance between soil moisture and oxygen, and a plant that has been infected by one disease is frequently vulnerable to invasion by secondary infections. The term "disease complex" refers to the aggregate of all plant-damaging agents [3].

The Extension Plant Pathology Team at the University of Nebraska- Lincoln Department of Plant Pathology created the content in this area. It is intended to assist crop producers, agricultural consultants, extension educators, and other agricultural professionals in Nebraska diagnose and control plant diseases, a significant yield limiting factor for many Nebraska crops. Finding a reliable diagnosis is the most important factor in the profitable management of plant diseases. The question of whether diseases will strike Nebraska in a particular year is irrelevant; what matters is which illnesses strike, how frequently, and how severely [4].

Disease prevention techniques

Plant diseases can cause significant harm to crops and gardens,reducing yield and quality. To prevent and manage plant diseases, it's important to follow these best practices:

Proper planting: Make sure to plant crops in well-draining soil in a location that provides adequate air circulation to prevent fungal diseases from spreading.

Crop rotation: Rotating crops annually helps reduce the buildup of disease-causing organisms in the soil.

Proper watering: Overwatering can lead to an increase in fungal diseases, so it's important to water plants thoroughly, but infrequently, and avoid getting the leaves wet.

Sanitation: Remove and destroy infected plant parts, including leaves and fruits, to reduce the spread of disease.

Fertilization: Provide plants with the proper nutrients to promote healthy growth and increase their resistance to disease.

Chemical control: If necessary, fungicides and insecticides can be used to control specific diseases and pests. However, it's important to follow label instructions and to rotate the use of different chemicals to avoid the development of resistance [5].

Monitoring: Regularly inspect plants for signs of disease, such as yellowing leaves, discoloration, or wilting, and take action if necessary.

By following these guidelines, you can help prevent and manage plant diseases and maintain a healthy garden or farm.


In conclusion, bacteria that have the ability to commandeer the cellular machinery and nutrition in our bodies are what cause infectious diseases. There is no one approach to effectively control the spread of infectious diseases; instead, it requires collaboration between people, communities, and healthcare institutions.
