What are the main causes of plant diseases?

Most plant diseases – around 85 percent – are caused by fungal or fungal-like organisms. However, other serious diseases of food and feed crops are caused by viral and bacterial organisms. Certain nematodes also cause plant disease.

What are the three major factors involved in the development of disease in plants?

Plant diseases– their occurrence and severity– result from the impact of three factors: the host plant, the pathogen, and the environmental conditions. This is represented with the disease triangle. If any one of the three factors is missing, the triangle is not complete, no disease will occur.

Symptoms of common plant infections are shown in the slideshow below.

Can viruses jump from plants to humans?

Direct plant-to-human transmission This is a very rare and highly unlikely event as, to enter a cell and replicate, a virus must “bind to a receptor on its surface, and a plant virus would be highly unlikely to recognize a receptor on a human cell. One possibility is that the virus does not infect human cells directly.

What factors contribute to disease?
