Similarly to apple trees, crown rots of strawberries caused by P. cactorum can be partially diagnosed by cutting the crown of the plant and observing brown vascular tissues, and root rots by brown or black stunted roots. [7] Leather rot of strawberry is an additional disease affecting strawberry plants, with P. cactorum being the causal agent ...
Laminated root rot also known as yellow ring rot is caused by the fungal pathogen Phellinus weirii. Laminated root rot is one of the most damaging root disease amongst conifers in northwestern America and true firs , Douglas fir , Mountain hemlock , and Western hemlock are highly susceptible to infection with P. weirii .
Armillaria root rot is a fungal root rot caused by several different members of the genus Armillaria. The symptoms are variable depending on the host infected, ranging from stunted leaves to chlorotic needles and dieback of twigs and branches. However, all infected hosts display symptoms characteristic of being infected by a white rotting ...
Pythium-induced root rot is a common crop disease. When the organism kills newly emerged or emerging seedlings, it is known as damping off, and is a very common problem in fields and greenhouses. [2] Thus there is tremendous interest in genetic host resistance, but no crop has ever developed adequate resistance to Pythium. [3]
These basidiospores are carried long distances by wind currents. They infect trees (usually conifers) through damage such as freshly cut stumps. Once on the stump the fungus colonizes and moves into the root via mycelium. Heterobasidion annosum moves short distances from the roots of an infected stump through root grafts with other trees. It ...
