Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. [ 1 ] It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with ...

Brown root rot disease is a destructive plant disease caused by fungi, primarily Phellinus noxius. [1] It affects a wide range of plants, including trees, shrubs, and crops, leading to root decay, poor growth, and often the death of the plant. This disease is common in tropical and subtropical regions with warm, moist climates. [2]
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 ...
Phytophthora cinnamomi is the leading cause of damage to avocado trees, and is commonly known as "root rot" amongst avocado farmers. Since the 1940s various breeds of root rot-resistant avocados have been developed to minimize tree damage. Damaged trees generally die or become unproductive within three to five years.
Silvicultural control involves planting species with low susceptibility. This could lower the root rot problem and free an infected site from inoculum. A more extreme measure is to remove the inoculum from the infected site. Proper planning and mixture schemes produce a better yield than a pure plantation (i.e. containing only one species).

Blossom end rot on a grape tomato. Calcium deficiency symptoms appear initially as localized tissue necrosis leading to stunted plant growth, necrotic leaf margins on young leaves or curling of the leaves, and eventual death of terminal buds and root tips. Generally, the new growth and rapidly growing tissues of the plant are affected first.
