Puccinia Malvacearum
''Puccinia malvacearum'' on '' Pelargonium'' geranium ''Puccinia malvacearum'', also known as hollyhock or mallow rust, is a species within the genus ''Puccinia'' known for attacking members of the family Malvaceae. An autoecious pathogen, it can complete its life cycle using a single host. Plants affected by the rust include ''Abutilon'', ''Alcea'' (Hollyhock), ''Hibiscus'', ''Lavatera'', ''Malva'', ''Malvastrum'' and ''Sphaeralcea''. Suggested control measures include sanitation (removal or destruction of affected plants or plant portions) or treatment with fungicides.

Carlo Luigi Giuseppe Bertero
Luigi Carlo Giuseppe Bertero (b. Santa Vittoria d'Alba, October 14, 1789 d. April 1831, – South Pacific Ocean) was an Italian physicist, physician, naturalist, botanist, bryologist and pteridologist. He explored the West Indies between 1816 and 1821 coinciding with the Venezuelan scientist and later president, José María Vargas in Puerto Rico although there is no evidence of any exchange between them. During his two voyages, February 1828 to September 1830 and between March and May 1830, he collected and described the flora of Chile. He also examined plants native to the Pacific island of Juan Fernandez, as well as Guadeloupe, Haiti, Puerto Rico, and Colombia. He is presumed lost in a shipwreck while sailing from Tahiti to Chile. Eponyms The American teacher, ornithologist and botanist Ralph Hoffman (1870–1932) named a cactus, Opuntia berteri, after Bertero. The genus Berteroa is named after Carlo Berteroa Bertero.

Galls
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology. In human pathology, a gall is a raised sore on the skin, usually caused by chafing or rubbing. Causes of plant galls Insects and mites Insect galls are the highly distinctive plant structures formed by some herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Galls act as both the habitat a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Of North America
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Nebraska
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Agricultural Extension
Agricultural extension is the application of scientific research and new knowledge to agricultural practices through farmer education. The field of 'extension' now encompasses a wider range of communication and learning activities organized for rural people by educators from different disciplines, including agriculture, agricultural marketing, health, and business studies. Extension practitioners can be found throughout the world, usually working for government agencies. They are represented by several professional organizations, networks and extension journals. Agricultural extension agencies in developing countries receive large amounts of support from international development organizations such as the World Bank and the Food and Agriculture Organization of the United Nations. Extension terminology The use of the word 'extension' originated in england in 1866.Modern extension began in Dublin, Ireland in 1847 with Lord Clarendon's itinerant instructors during the great fami ...

Fungicide
Fungicides are biocidal chemical compounds or biological organisms used to kill parasitic fungi or their spores. A fungistatic inhibits their growth. Fungi can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit. Fungicides are used both in agriculture and to fight fungal infections in animals. Chemicals used to control oomycetes, which are not fungi, are also referred to as fungicides, as oomycetes use the same mechanisms as fungi to infect plants. Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant. Some are locally systemic, and some move upwardly. Most fungicides that can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
