Drechslera avenacea is a fungal plant pathogen. [1]
Hosts are Avena spp. [2] Includes wild oats, for which it is a bioherbicide. [2]
Ghajar et al., 2006 investigates and provides culturing parameters. [2]
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.
Bioherbicides are herbicides consisting of phytotoxins, pathogens, and other microbes used as biological weed control. Bioherbicides may be compounds and secondary metabolites derived from microbes such as fungi, bacteria or protozoa; or phytotoxic plant residues, extracts or single compounds derived from other plant species.
Centaurea diffusa, also known as diffuse knapweed, white knapweed or tumble knapweed, is a member of the genus Centaurea in the family Asteraceae. This species is common throughout western North America but is not actually native to the North American continent, but to the eastern Mediterranean.
Apple scab is a common disease of plants in the rose family (Rosaceae) that is caused by the ascomycete fungus Venturia inaequalis. While this disease affects several plant genera, including Sorbus, Cotoneaster, and Pyrus, it is most commonly associated with the infection of Malus trees, including species of flowering crabapple, as well as cultivated apple. The first symptoms of this disease are found in the foliage, blossoms, and developing fruits of affected trees, which develop dark, irregularly-shaped lesions upon infection. Although apple scab rarely kills its host, infection typically leads to fruit deformation and premature leaf and fruit drop, which enhance the susceptibility of the host plant to abiotic stress and secondary infection. The reduction of fruit quality and yield may result in crop losses of up to 70%, posing a significant threat to the profitability of apple producers. To reduce scab-related yield losses, growers often combine preventive practices, including sanitation and resistance breeding, with reactive measures, such as targeted fungicide or biocontrol treatments, to prevent the incidence and spread of apple scab in their crops.
Beauveria bassiana is a fungus that grows naturally in soils throughout the world and acts as a parasite on various arthropod species, causing white muscardine disease; it thus belongs to the group of entomopathogenic fungi. It is used as a biological insecticide to control a number of pests, including termites, thrips, whiteflies, aphids and various beetles. Its use in the control of bedbugs and malaria-transmitting mosquitos is under investigation.
A biopesticide is a biological substance or organism that damages, kills, or repels organisms seen as pests. Biological pest management intervention involves predatory, parasitic, or chemical relationships.
Trichogramma is a genus of minute polyphagous wasps that are endoparasitoids of insect eggs. Trichogramma is one of around 80 genera from the family Trichogrammatidae, with over 200 species worldwide.
Avena sterilis is a species of grass weed whose seeds are edible. Many common names of this plant refer to the movement of its panicle in the wind.
Drechslera is a genus of fungi. Many of the species in this genus are plant pathogens.
Ageratina riparia, commonly known as mistflower, is a species of flowering plant in the family Asteraceae, native to Mexico. The species is widely adventive and has spread to Cuba, Jamaica, and other parts of the Caribbean. It has also been introduced as an ornamental plant and naturalized in a variety of regions, including parts of Hawaii, South Africa, Southeast Asia, Macaronesia, Oceania, Peru, and the Indian subcontinent. In tropical climates, A. riparia is highly invasive and a variety of control methods have been developed to reduce its spread.
Trichosirocalus horridus is a species of true weevil, native to Europe. It is a biological pest control agent that was introduced into the United States in 1974 to control exotic thistles, especially in the Cirsium and Carduus genera.
Eccritotarsus catarinensis is a species of plant bug from Santa Catarina, Brazil. It is a sap-feeding mirid that removes a considerable amount of chlorophyll from water hyacinth.
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.
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.
Digitivalva delaireae is a moth of the family Acrolepiidae that is endemic to South Africa.
Bikasha collaris is a species of flea beetle in the family Chrysomelidae. It is found in China, Taiwan, and Japan.
A mycoparasite is an organism with the ability to parasitize fungi.
Rice-sheath blight is a disease caused by Rhizoctonia solani, a basidiomycete, that causes major limitations on rice production in India and other countries of Asia. It is also a problem in the southern US, where rice is also produced. It can decrease yield up to 50%, and reduce its quality. It causes lesions on the rice plant, and can also cause pre- and post-emergence seedling blight, banded leaf blight, panicle infection and spotted seed.
Puccinia myrsiphylli is a rust fungus in the genus Puccinia, family Pucciniaceae, and is native to South Africa. It has been tested, introduced, and targeted in Australia and New Zealand as an effective biocontrol agent for Asparagus asparagoides, also known as bridal creeper.
Megamelus scutellaris, the water hyacinth planthopper, is a true bug native to South America. It is used as a biological control agent to manage and reduce the spread of the water hyacinth, an invasive aquatic plant native to South America that has invaded many freshwater systems globally.
