Peach leaf curl is a plant disease characterized by distortion and coloration of leaves and is caused by the fungus Taphrina deformans, which infects peach, nectarine, and almond trees. T. deformans is found in the United States, Europe, Asia, Africa, Australia, and New Zealand. Peach leaf curl reduces the amount of leaves and fruit produced by peach and nectarine trees.
Trichoderma viride is a fungus and a biofungicide.
d'Arenberg is an Australian wine company founded in 1912. All of its vineyards are located in South Australia's McLaren Vale wine region, although some of the wines they make are produced from grapes sourced from the Adelaide Hills wine region and other parts of the Fleurieu zone. It is now owned by the fourth generation of the Osborn family, headed by Chester Osborn. d'Arenberg are known for the quirky names of their wines, and their specialism in the vines of the Rhône valley. They also produce many of their wines in a traditional manner, using basket pressing for both reds and whites and leaving the vast majority of the red wines unfiltered and unfined which can cause the wine to throw a sediment in bottle but leaves the flavour intact. The majority of their red wines are suitable for ageing as well as for drinking fairly young and even the cheaper wines show very well after a few years in bottle. Perhaps their best known wine is 'The Dead Arm Shiraz', made from fungus-infected shiraz grape vines.
Phomopsis cane and leaf spot occurs wherever grapes are grown. Phomopsis cane and leaf spot is more severe in grape-growing regions characterized by a humid temperate climate through the growing season. Crop losses up to 30% have been reported to be caused by Phomopsis cane and leaf spot.
Nectria cinnabarina, also known as coral spot, is a plant pathogen that causes cankers on broadleaf trees. This disease is polycyclic and infects trees in the cool temperate regions of the Northern Hemisphere. N. cinnabarina is typically saprophytic, but will act as a weak parasite if presented with an opportunity via wounds in the tree or other stressors that weaken the tree's defense to the disease. A study published in 2011 showed that this complex consists of at least 4 distinct species. There are only a few ways to manage this disease with techniques such as sanitation and pruning away branches that have the cankers. N. cinnabarina is not as significant a problem as other Nectria spp., some of which are the most important pathogens to infect hardwood trees.
Phytophthora × cambivora is a plant pathogen that causes ink disease in European chestnut trees. Ink disease, also caused by Phytophthora cinnamomi, is thought to have been present in Europe since the 18th century, and causes chestnut trees to wilt and die; major epidemics occurred during the 19th and 20th centuries. P. cinnamomi and P. × cambivora are now present throughout Europe since the 1990s. Ink disease has resurged, often causing high mortality of trees, particularly in Portugal, Italy, and France. It has also been isolated from a number of different species since the 1990s, including:
Botryosphaeria stevensii is a fungal plant pathogen that causes cankers on several tree species including apple and juniper as well as causing cankers on grape vines. It causes branch dieback, possibly affecting a large portion of the tree canopy, and if severe it can kill entire plants.
Lasiodiplodia theobromae is a plant pathogen with a very wide host range. It causes rotting and dieback in most species it infects. It is a common post harvest fungus disease of citrus known as stem-end rot. It is a cause of bot canker of grapevine. It also infects Biancaea sappan, a species of flowering tree also known as Sappanwood.
Cadophora malorum is a saprophytic plant pathogen that causes side rot in apple and pear and can also cause disease on asparagus and kiwifruit. C. malorum has been found parasitizing shrimp and other fungal species in the extreme environments of the Mid-Atlantic Ridge, and can be categorized as a halophilic psychrotrophic fungus and a marine fungus.
Verticillium dahliae is a fungal plant pathogen. It causes verticillium wilt in many plant species, causing leaves to curl and discolor. It may cause death in some plants. Over 400 plant species are affected by Verticillium complex.
Nigrospora sphaerica is an airborne filamentous fungus in the phylum Ascomycota. It is found in soil, air, and plants as a leaf pathogen. It can occur as an endophyte where it produces antiviral and antifungal secondary metabolites. Sporulation of N. sphaerica causes its initial white coloured colonies to rapidly turn black. N. sphaerica is often confused with the closely related species N. oryzae due to their morphological similarities.
The fungal genus Truncatella in the family Sporocadaceae, and in the Amphisphaeriales order, includes plant pathogens such as Truncatella laurocerasi.
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 fungus. The most effective ways of management focus on limiting the spread of the fungus, planting resistant species, and removing infected material. This disease poses a threat to the lumber industry as well as affecting recreational areas.
Grapevine trunk diseases (GTD) are the most destructive diseases of vineyards worldwide. Fungicides with the potential to control GTD have been banned in Europe and there are no highly effective treatments available. Action to develop new strategies to fight these diseases are needed.
Dothiorella moneti is an endophytic fungus that might be a canker pathogen, specifically for Eucalyptus gomphocephala. It was isolated from said trees in Western Australia.
Dothiorella santali is an endophytic fungus that might be a canker pathogen, specifically for Eucalyptus gomphocephala. It was isolated from said trees in Western Australia.
Curvularia inaequalis is a plant saprobe that resides in temperate and subtropical environments. It is commonly found in the soils of forage grasses and grains. The species has been observed in a broad distribution of countries including Turkey, France, Canada, The United States, Japan and India. This species is dematiaceous and a hyphomycete.
Sporocadus is a genus of plant pathogens in the family Sporocadaceae.
The 2020 table grape harvest was worth $2.12 billion while wine grapes brought in $1.7 billion, down 15.3% year-on-year. By weight this was 17% lower versus 2018. The next year, 2021 saw a much better yield. From 829,000 acres (335,000 ha) viniculturists got 6.94 short tons per acre (15.6 t/ha) for a total harvest of 5,755,000 short tons (5,221,000 t). At an average of $909 per short ton ($1,002/t) they were paid $5,229,902,000 for the season. Of that, 4,844,600 short tons (4,394,900 t) were for destined for processing industries and at $835 per short ton ($920/t) that was worth $4,046,382,000. The fresh harvest was 910,400 short tons (825,900 t) and selling at a price of $1,300 per short ton ($1,433/t), this sector was worth $1,183,520,000 for the season.
Coniothyriaceae is a family of ascomycetous marine based fungi within the order of Pleosporales in the subclass Pleosporomycetidae and within the class Dothideomycetes. They are pathogenic or they can be saprobic on dead branches. They are generally a anamorphic species.
