Sclerotinia minor (white mold) is a plant pathogen infecting Chicory, Radicchio, [1] carrots, tomatoes, sunflowers, peanuts and lettuce. [2]
Gossypium is a genus of flowering plants in the tribe Gossypieae of the mallow family, Malvaceae, from which cotton is harvested. It is native to tropical and subtropical regions of the Old and New Worlds. There are about 50 Gossypium species, making it the largest genus in the tribe Gossypieae, and new species continue to be discovered. The name of the genus is derived from the Arabic word goz, which refers to a soft substance.
Lettuce is an annual plant of the family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, celtuce, is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. As of 2021, world production of lettuce and chicory was 27 million tonnes, 53 percent of which came from China.
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs.
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".
Leaf vegetables, also called leafy greens, pot herbs, vegetable greens, or simply greens, are plant leaves eaten as a vegetable, sometimes accompanied by tender petioles and shoots. Leaf vegetables eaten raw in a salad can be called salad greens.
Helotiales is an order of the class Leotiomycetes within the division Ascomycota. The taxonomy within Helotiales has been debated. It has expanded significantly as genomic techniques for taxonomical identification have become more commonly used. As of February 2020, the order is estimated to contain 30 accepted families, 519 genera, and 6266 species.
Mycoviruses, also known as mycophages, are viruses that infect fungi. The majority of mycoviruses have double-stranded RNA (dsRNA) genomes and isometric particles, but approximately 30% have positive-sense, single-stranded RNA (+ssRNA) genomes.
Sclerotinia sclerotiorum is a plant pathogenic fungus and can cause a disease called white mold if conditions are conducive. S. sclerotiorum can also be known as cottony rot, watery soft rot, stem rot, drop, crown rot and blossom blight. A key characteristic of this pathogen is its ability to produce black resting structures known as sclerotia and white fuzzy growths of mycelium on the plant it infects. These sclerotia give rise to a fruiting body in the spring that produces spores in a sac which is why fungi in this class are called sac fungi (Ascomycota). This pathogen can occur on many continents and has a wide host range of plants. When S. sclerotiorum is onset in the field by favorable environmental conditions, losses can be great and control measures should be considered.
Sclerotinia trifoliorum is a plant pathogen infecting alfalfa, red clover, chickpea, and fava bean. Lithourgidis et al. have done much work on this disease and fava bean.
The Muck Crops Research Station is an agriculture research facility near Kettleby and Ansnorveldt, in Ontario, Canada. It is operated by the Office of Research at the University of Guelph.
Ulocladium is a genus of fungi. Species of this genus contain both plant pathogens and food spoilage agents. Other species contain enzymes that are biological control agents. Some members of the genus can invade homes and are a sign of moisture because the mold requires water to thrive. They can cause plant diseases or hay fever and more serious infections in immuno-suppressed individuals.
The Sclerotiniaceae are a family of fungi in the order Helotiales. Many species in this family are plant pathogens.
A lettuce sandwich is a wrap with lettuce substituted for the bread, or a sandwich with a filling consisting primarily of lettuce. It should not be confused with other sandwiches that use lettuce as one of many ingredients, such as the BLT sandwich or the tomato and lettuce sandwich. The lettuce sandwich has a long history in both the United States and the United Kingdom. It has been used as a metaphor to represent things like mundanity, weakness and poverty. In more recent times, the lettuce sandwich, including lettuce hamburgers have symbolized diets including the keto diet.
Sclerotinia is a genus of fungi in the family Sclerotiniaceae. The widely distributed genus contains 14 species.
Toxomerus marginatus, also known as the margined calligrapher fly, is a common species of hoverfly. It is found in many parts of North America.
Phasmarhabditis hermaphrodita is a facultative parasitic nematode that can kill slugs and snails. It belongs to the family Rhabditidae, the same family as Caenorhabditis elegans.
A mycoparasite is an organism with the ability to parasitize fungi.
Trichoderma hamatum is a species of fungus in the family Hypocreaceae. It has been used a biological control of certain plant diseases, including Sclerotinia lettuce drop caused by Sclerotinia minor.
