Pucciniastrum americanum is a plant pathogen infecting caneberries. [1] [2]
Rubus spectabilis, the salmonberry, is a species of bramble in the rose family Rosaceae, native to the west coast of North America from west-central Alaska to California, inland as far as Idaho. Like many other species in the genus Rubus, the salmonberry plant bears edible fruit, typically yellow-orange or red in color, resembling raspberries in appearance.
Hemileia vastatrix is a multicellular basidiomycete fungus of the order Pucciniales that causes coffee leaf rust (CLR), a disease affecting the coffee plant. Coffee serves as the obligate host of coffee rust, that is, the rust must have access to and come into physical contact with coffee in order to survive.
Eriophyidae is a family of more than 200 genera of mites, which live as plant parasites, commonly causing galls or other damage to the plant tissues and hence known as gall mites. About 3,600 species have been described, but this is probably less than 10% of the actual number existing in this poorly researched family. They are microscopic mites and are yellow to pinkish white to purplish in color. The mites are worm like, and have only two pairs of legs. Their primary method of population spread is by wind. They affect a wide range of plants, and several are major pest species causing substantial economic damage to crops. Some species, however, are used as biological agents to control weeds and invasive plant species.
Puccinia xanthii is a plant pathogen infecting sunflowers. It also causes rust on Xanthium occidentale and can be used as a form of biological control where this plant is an invasive species.
Naohidemyces vaccinii is a plant pathogen that affects members of the Vaccinium and Tsuga genera, causing leaf rust on lingonberries, blueberries, and cranberries, and early needle cast on hemlocks. Naohidemyces vaccinii is found on the Vaccinium genus in Canada, the United States, the United Kingdom, Europe, Russia, China, Korea, and Japan, and on hemlock in AK, ID, WA in the United States, BC in Canada, and Japan.
Pucciniastrum coryli is a fungal plant pathogen infecting hazelnuts. It forms ochraceous rust pustules on the leaves. Also commonly known as hazel rust.
Xiphinema americanum, the American dagger nematode, is a species of plant pathogenic nematodes. It is one of many species that belongs to the genus Xiphinema. It was first described by N. A. Cobb in 1913, who found it on both sides of the United States on the roots of grass, corn, and citrus trees. Not only is Xiphinema americanum known to vector plant viruses, but also X. americanum has been referred to as "the most destructive plant parasitic nematode in America", and one of the four major nematode pests in the Southeastern United States.
Tomato ringspot virus (ToRSV) is a plant pathogenic virus of the family Secoviridae. It affects species of cucumber, tobacco, tomato, cowpea, among others. It causes ringspots in tobacco plants and raspberries, yellow bud mosaic in peaches, yellow vein in grapes, and stunted growth in gladiolus and Narcissus. Its range is in the temperate regions of North America, especially where its vector, Xiphinema americanum is present. Along with the adult and larval stages of this nematode, the virus is also spread by seed. This type of infection is more common in strawberries and soybeans than any other susceptible plant.
Chondrilla juncea is a species of flowering plant in the family Asteraceae known by a number of common names, including rush skeletonweed, gum succory, devil's grass, and nakedweed. The plant is native to Europe, Asia, and North Africa, but it is known throughout most temperate regions of the world as an introduced species which is usually considered a noxious weed.
Pucciniastrum is a genus of Basidiomycota fungi. Pucciniastrum species, like all rust fungi, are obligate plant parasites.
This article summarizes different crops, what common fungal problems they have, and how fungicide should be used in order to mitigate damage and crop loss. This page also covers how specific fungal infections affect crops present in the United States.
Puccinia jaceae var. solstitialis is a species of fungus in the Pucciniaceae family. It is a plant pathogen that causes rust. Native to Eurasia, it is the first fungal pathogen approved in the United States as a biological control agent to curb the growth of the invasive weed yellow starthistle.
Austropuccinia is a monotypic genus of rust native to South America with the only species Austropuccinia psidii, commonly known as myrtle rust, guava rust, or ʻōhiʻa rust. It affects plants in the family Myrtaceae. It is a member of the fungal complex called the guava rust group. The spores have a distinctive yellow to orange colour, occasionally encircled by a purple ring. They are found on lesions on new growth including shoots, leaves, buds and fruits. Leaves become twisted and may die. Infections in highly susceptible species may result in the death of the host plant.
Gymnoconia is a genus of rust fungi in the family Phragmidiaceae. G. nitens causes an orange rust of Rubus species.
Ribes americanum is a North American species of flowering plant in the gooseberry family known as wild black currant, American black currant, and eastern black currant. It is widespread in much of Canada and the northern United States.
Gustav Heinrich Otth was a Swiss mycologist and military officer. He was the brother of naturalist Carl Adolf Otth (1803–1839).
Gymnoconia interstitialis, otherwise known as orange rust of raspberries, is a well-known disease of raspberries and blackberries throughout the eastern United States and southern Canada. The disease targets the usefulness of the leaves, attacking them until they die and fall off of the plant. The disease returns annually, and this recurrence essentially makes the plants worthless—rarely do affected plants recover. Some strains have such a strong impact on the plants that the cultivation becomes unprofitable. Hesler & Whetzel (1917) claim, "Ten per cent rusty plants are frequently reported. Twenty-five per cent or more are recorded."
Stephen Wilhelm was a professor of plant pathology, known for his success in controlling Verticillium wilt. His research on plant hybridization and soil fumigation contributed to revolutionary developments in the strawberry and raspberry industries.
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.
