Spring Infection: two types of spores are produced in spring which can infect blossoms. Conidia are produced on cankers and fruit mummies on the tree. Apothecia (small mushroom-like structures) form on mummies lying on the ground. [3] The apothecia discharge ascospores during the bloom period, but don't contribute to fruit infection later in ...

Fruit rot caused by the brown rot pathogen Monilinia fructigena is a notorious ailment found in Malus domestica—the apple tree—with the fungus occasionally spreading from the infected fruit to the branches, causing cankering. With apple infections, a varying symptom can occur within the fruits, causing what is commonly known as “black ...
Therefore, it is not economically viable to try to control them, except when they infect perennial species, such as fruit trees. [citation needed] Most plant viruses have small, single-stranded RNA genomes. Some also have double stranded RNA or single or double stranded DNA.
Cankers and other dead wood and bark tissue, as well as mummified fruit (fruit infected by the pathogen and remaining in the orchard) serve as sources of primary and secondary inoculum. [8] Both pycnidia and pseudothecia are observed on plant tissues, producing conidia and ascospores. [3] [8] Conidia are produced in greater numbers. [7]

Penicillium digitatum (/ ˌ p ɛ n ɪ ˈ s ɪ l i əm ˌ d ɪ dʒ ɪ ˈ t eɪ t əm /) is a mesophilic fungus found in the soil of citrus-producing areas. [1] [2] [3] It is a major source of post-harvest decay in fruits and is responsible for the widespread post-harvest disease in Citrus fruit known as green rot or green mould.
Monilinia laxa is an ascomycete fungus that is responsible for the brown rot blossom blight disease that infects many different types of stone fruit trees, such as apricots, cherries and peaches. [2] It can also occasionally affect some pome fruits; for example, apples and pears. [ 3 ]
