This category includes economically significant plant diseases and the organisms that cause them including, fungi, bacteria, protists and viruses. For more information on plant pathology see phytopathology. For insects that transmit plant pathogens see Insect vectors of plant pathogens.
A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]
A soil borne pathogen is a disease-causing agent which lives both in soil and in a plant host, and which will tend to infect undiseased plants which are grown in that soil. [1] Common soil borne pathogens include Fusarium, [1] Pythium, [1] [2] Rhizoctonia, [1] Phytophthora, [1] Verticillium, [1] Rhizopus, [2] Thielaviopsis, [2] and nematodes [1 ...
The patterns may appear on a few or many leaves. Plants are infected by this virus at propagation using infected plant material. [4] Rose wilt – Rose wilt is a complex of viruses and is referred to as "dieback" in some areas. The disease can be spread by vectors such as aphids. Symptoms are variable and range from stunted growth to curled ...
When the smut invades the host plant it causes hypertrophy – the host's cells increase in size and number. (The fungus also destroys the flowering structures of the plant, so it does not make seed, but the plants can still be propagated asexually by rhizome.) In an environment such as a rice paddy, new sprouts of wild rice are easily infected ...
