Monilinia rubi is a species of fungus in the family Sclerotiniaceae. The species is a plant pathogen causing "dry berry disease" of caneberries. The species was formerly known by the invalidly published name Rhizoctonia rubi. [1]
The blackberry is an edible fruit produced by many species in the genus Rubus in the family Rosaceae, hybrids among these species within the subgenus Rubus, and hybrids between the subgenera Rubus and Idaeobatus. The taxonomy of blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. For example, the entire subgenus Rubus has been called the Rubus fruticosus aggregate, although the species R. fruticosus is considered a synonym of R. plicatus.
Botrytis cinerea is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold".
The Pseudomonadales are an order of Pseudomonadota. A few members are pathogens, such as species of Pseudomonas, Moraxella, and Acinetobacter, which may cause disease in humans, animals and plants.
Phytophthora drechsleri is a plant pathogen with many hosts.
Monilinia laxa is a plant pathogen that is the causal agent of brown rot of stone fruits.
Mycosphaerella coffeicola is a sexually reproducing fungal plant pathogen. It is most commonly referred to as the asexual organism Cercospora coffeicola.
Colletotrichum kahawae is a fungal plant pathogen that causes coffee berry disease (CBD) on Coffea arabica crops. The pathogen is an ascomycete that reproduces asexually. The asexual spores (conidia) are stored within acervuli. This disease is considered to be one of the major factors hampering C.arabica production in the African continent, which represents the current geographic range of the fungus. Coffee berry disease causes dark necrosis in spots and causes the green berries of the coffee to drop prematurely. High humidity, relatively warm temperatures, and high altitude are ideal for disease formation. Given the severity of the disease and the lack of effective control measures, there is great concern that the fungus may spread to other coffee producing continents, such as South America, which could have catastrophic consequences.
Peronospora sparsa is an oomycete plant pathogen that causes downy mildew in berry producing plants; especially in the genus's Rubus and Rosa. Downy mildew plant pathogens are often host specific and cause problems in cloudberries, blackberries, boysenberries, strawberries, and arctic bramble. Since they are host specific, Peronospora sparsa will not cause downy mildew in grapes because a different plant pathogen causes downy mildew in grapes; Plasmopara viticola. Although it depends on the cultivar, symptoms do not normally start until later stages of disease and can look different on different plants. The most common symptoms include red lesions in the veins of leaves, with dry and deformed berries.
Verticillium albo-atrum is a plant pathogen with many hosts.
Phytophthora fragariae is a fungus-like (oomycete) plant pathogen that causes red stele, otherwise known as Lanarkshire disease, in strawberries. Symptoms of red stele can include a red core in the roots, wilting of leaves, reduced flowering, stunting, and bitter fruit. The pathogen is spread via zoospores swimming through water present in the soil, released from sporangia.
Monilinia azaleae is a species of fungus in family Sclerotiniaceae. A plant pathogen, it was first formally described by Edwin Earle Honey in 1936.
Elsinoë ampelina is a plant pathogen, which is the causal agent of anthracnose on grape.
Monilinia fructigena is a plant pathogen in the fungus kingdom causing a fruit rot of apples, pears, plums, peaches and cherries.
Phragmidium rubi-idaei is a plant pathogen infecting caneberries, Rubus spp.
Monilinia is a genus of fungi in the family Sclerotiniaceae.
Monilinia oxycocci (Woronin) Honey,, common names cranberry cottonball, cranberry hard rot, tip blight, is a fungal infection of large cranberry and small cranberry. The tips of young flowering shoots wilt before they flower. Fruit that forms on the plant can then be infected by the asexual spores traveling through the plant, causing the berries to harden, turn cottony on the inside, and dry out instead of maturing. The berries are filled with a cotton-like fungus and are generally yellowish with tan stripes or blotches at maturity, making them unmarketable. It results in important economic impacts on many cranberry marshes, particularly in Wisconsin.
Edwin Earle Honey was an American plant pathologist and mycologist. In 1936, he formally described the fungus and plant pathogen Monilinia azaleae, which preys upon crops and other plants in the families Rosaceae and Ericaceae.
Raspberry leaf spot is a plant disease caused by Sphaerulina rubi, an ascomycete fungus. Early symptoms of infection are dark green spots on young leaves. As the disease progresses, these spots turn tan or gray in color. Disease management strategies for raspberry leaf spots include the use of genetically resistant raspberry plant varieties, chemical fungicide sprays, and cultural practices such as pruning and thinning out canes.
Agriculture is a significant sector in California's economy, producing nearly US$50 billion in revenue in 2018. There are more than 400 commodity crops grown across California, including a significant portion of all fruits, vegetables, and nuts for the United States. In 2017, there were 77,100 unique farms and ranches in the state, operating across 25.3 million acres of land. The average farm size was 328 acres (133 ha), significantly less than the average farm size in the U.S. of 444 acres (180 ha).
Cranberry fruit rot (CFR) is a disease complex of multiple fungal agents affecting the American cranberry. Cranberry fruit rot can be categorized into field rot and storage rot. The importance of field rot and fruit rot depends on how the cranberries will be processed after harvest. If cranberries are immediately processed after harvest, growers focus on preventing field rot while with fresh market cranberries, growers seek to prevent storage rot. There are 10-15 fungal pathogens known to cause cranberry fruit rot diseases, some active in only field rot, storage rot, or both. The majority of these fungal pathogens are ascomycetes, with the rest being deuteromycetes. There is no known bacterial pathogen that plays a role in CFR or any major disease on cranberry, potentially due to the low pH conditions on the cranberry fruit.
