Fusarium ear blight (FEB), is a fungal disease of cereals, including wheat, barley, oats, rye and triticale. FEB is caused by a range of Fusarium fungi, which infects the heads of the crop, reducing grain yield. The disease is often associated with contamination by mycotoxins produced by the fungi already when the crop is growing in the field. The disease can cause severe economic losses as mycotoxin-contaminated grain cannot be sold for food or feed.
Fusarium oxysporum, an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans. It is part of the family Nectriaceae.
Basil, also called great basil, is a culinary herb of the family Lamiaceae (mints). It is a tender plant, and is used in cuisines worldwide. In Western cuisine, the generic term "basil" refers to the variety also known as sweet basil or Genovese basil. Basil is native to tropical regions from Central Africa to Southeast Asia. In temperate climates basil is treated as an annual plant, however, basil can be grown as a short-lived perennial or biennial in warmer horticultural zones with tropical or Mediterranean climates.
Fusarium wilt is a common vascular wilt fungal disease, exhibiting symptoms similar to Verticillium wilt. This disease has been investigated extensively since the early years of this century. The pathogen that causes Fusarium wilt is Fusarium oxysporum. The species is further divided into formae speciales based on host plant.
Panama disease is a plant disease that infects banana plants. It is a wilting disease caused by the fungus Fusarium oxysporum f. sp. cubense (Foc). The pathogen is resistant to fungicides and its control is limited to phytosanitary measures.
Downy mildew refers to any of several types of oomycete microbes that are obligate parasites of plants. Downy mildews exclusively belong to the Peronosporaceae family. In commercial agriculture, they are a particular problem for growers of crucifers, grapes and vegetables that grow on vines. The prime example is Peronospora farinosa featured in NCBI-Taxonomy and HYP3. This pathogen does not produce survival structures in the northern states of the United States, and overwinters as live mildew colonies in Gulf Coast states. It progresses northward with cucurbit production each spring. Yield loss associated with downy mildew is most likely related to soft rots that occur after plant canopies collapse and sunburn occurs on fruit. Cucurbit downy mildew only affects leaves of cucurbit plants.
Lemon basil, hoary basil, Thai lemon basil, or Lao basil, is a hybrid between basil and American basil. The herb is grown primarily in northeastern Africa and southern Asia for its fragrant lemon scent, and is used in cooking.
Gros Michel, often translated and known as "Big Mike", is an export cultivar of banana and was, until the 1950s, the main variety grown. The physical properties of the Gros Michel make it an excellent export produce; its thick peel makes it resilient to bruising during transport and the dense bunches that it grows in make it easy to ship.
Aphanomyces euteiches is a water mould, or oomycete, plant pathogen responsible for the disease Aphanomyces root rot. The species Aphanomyces euteiches can infect a variety of legumes. Symptoms of the disease can differ among hosts but generally include reduced root volume and function, leading to stunting and chlorotic foliage. Aphanomyces root rot is an important agricultural disease in the United States, Europe, Australia, New Zealand, and Japan. Management includes using resistant crop varieties and having good soil drainage, as well as testing soil for the pathogen to avoid infected fields.
Fusarium oxysporum f.sp. betae is a destructive fungal plant pathogen. It causes Fusarium yellows or fusarium wilt, characterized by yellowing and dwarfing.
Fusarium oxysporum f.sp. ciceris is a fungal plant pathogen that causes fusarium wilt of chickpea.
Fusarium redolens is a species of fungus in the genus Fusarium and family Nectriaceae. This species is a soil-borne plant pathogen in temperate prairies. It causes diseases such as root, crown, and spear rot, seedling damping-off, and wilting disease. It is a known producer of the alkaloids peimisine and imperialine-3β-d-glucoside, which has implications for traditional Chinese medicine.
Henry Luke Bolley was an American botanist and plant pathologist known for his work that led to the control or eradication of several major crop diseases. He was also a pioneering college football player and coach.
Orobanche aegyptiaca, the Egyptian broomrape, is a plant which is an obligate holoparasite from the family Orobanchaceae with a complex lifecycle. This parasite is most common in the Middle East and has a wide host range including many economically important crops.
Striga hermonthica, commonly known as purple witchweed or giant witchweed, is a hemiparasitic plant that belongs to the family Orobanchaceae. It is devastating to major crops such as sorghum and rice. In sub-Saharan Africa, apart from sorghum and rice, it also infests maize, pearl millet, and sugar cane.
Black rot, caused by the bacterium Xanthomonas campestris pv. campestris (Xcc), is considered the most important and most destructive disease of crucifers, infecting all cultivated varieties of brassicas worldwide. This disease was first described by botanist and entomologist Harrison Garman in Lexington, Kentucky, US in 1889. Since then, it has been found in nearly every country in which vegetable brassicas are commercially cultivated.
Fusarium oxysporum f. sp. cubense is a fungal plant pathogen that causes Panama disease of banana, also known as fusarium wilt of banana. The fungi and the related disease are responsible for widespread pressure on banana growing regions, destroying the economic viability of several commercially important banana varieties.
The Celebrity tomato cultivar is a hybrid (biology) that produces long fruit-bearing stems holding 20 or more very plump, robust tomatoes. Fruits weigh approximately 8 oz., and are 4 inches across. Plants need caging or staking, and produce fruit throughout the growing season. The celebrity tomato is a cultivar of the species Solanum lycopersicum. It is a crossbreed of the common tomato that is widely used for various culinary purposes. This tomato is of great size and is known to be resistant to most tomato diseases such as Fusarium wilt, Verticillium wilt, Tobacco mosaic virus and Root-knot nematode due to its hybrid nature. Celebrity tomatoes are highly adaptive to harsh environments and can grow in a wide range of places including dry, humid and wet regions. They are resistant to cracking and splitting which usually occurs when there is an excess of water and sugar movement in the fruits. Therefore, causing the tomato skin to grow at a slower rate compared to the expansion of the fruit. They can survive in harsh uneven rainfall. However, they are highly susceptible to colder environments and are at a higher risk of dying in regions with short growing seasons. The plants can grow up to 5 feet in height with bright red medium-sized fruits. The plants are generally very thick and grow in clusters. The tomato fruits are mostly used in the making of various salsas, salads, juices and canned food.
Koa wilt is a relatively new disease to Hawaii, discovered in 1980. Koa wilt is caused by a forma specialis of the fungus Fusarium oxysporum, which is now abundant in Hawaiian soils and infects the native Acacia koa tree, a once-dominant species in the canopy of Hawaiian forests. Fusarium oxysporum f.sp. koae is believed to have been brought into Hawaii on an ornamental acacia plant. Fusarium fungi clog the tree xylem, causing significant wilt and mortality among these beautiful and iconic Hawaiian trees.
Vascular wilt in the perennial shrub lulo or naranjilla is a disease caused by the fungus Fusarium oxysporum f. sp. quitoense.
