Rigidoporus Microporus
''Rigidoporus microporus'' is a plant pathogen, known to cause white root rot disease on various tropical crops, such as cacao, cassava, tea, with economical importance on the para rubber tree ('' Hevea brasiliensis''). White root rot of rubber ''Rigidoporus lignosus'' (klotzsch) Imazeki, the causal agent of white root rot, was first reported on rubber in 1904 from Botanical Gardens, Singapore. It belongs to the order Basidiomycete, and in the family Polyporaceae. The disease originates on roots and later spreads to collar region. Foliar symptoms are initiated subsequently with the destruction of the root system. Its above ground symptoms indicates that the trees are mostly beyond treatment and recovery, as rapid progress of infection makes death imminent. This disease caused significant mortality to tree irrespective of age or health status, causing economic losses to the latex industry in many countries. It is the most destructive root disease in rubber plantations in Sri Lanka ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casper Van Overeem
Casper van Overeem (1 October 1893 – 27 February 1927) was a Dutch mycologist. He was known for his studies on the fungal flora of Indonesia. He received his PhD from the University of Zurich in 1920, with a dissertation titled ''Über Formen abweichender Chromosomenzahl bei Oenothera'' ("About forms differing in chromosome number in '' Oenothera''"). Shortly after, he went to Bogor, where he worked as an assistant in the mycology herbarium. Eponymous taxa *'' Overeemia'' G.Arnaud (1954) *'' Catillaria overeemii'' Zahlbr.

Hevea Brasiliensis
''Hevea brasiliensis'', the Pará rubber tree, ''sharinga'' tree, seringueira, or most commonly, rubber tree or rubber plant, is a flowering plant belonging to the spurge family Euphorbiaceae Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as '' Euphorbia paralias'', are herbs, but some, ... originally native to the Amazon basin, but is now pantropical in distribution due to introductions. It is the most economically important member of the genus ''Hevea'' because the milky latex extracted from the tree is the primary source of natural rubber. Description ''H. brasiliensis'' is a tall deciduous tree growing to a height of up to in the wild, but cultivated trees are usually much smaller because drawing off the latex restricts the growth of the tree. The trunk is cylindrical and may have a swollen, bottle-shaped base. The bark is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tectona Grandis
Teak (''Tectona grandis'') is a tropical hardwood tree species in the family Lamiaceae. It is a large, deciduous tree that occurs in mixed hardwood forests. ''Tectona grandis'' has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs ( perfect flowers). The large, papery leaves of teak trees are often hairy on the lower surface. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects. ''Tectona grandis'' is native to south and southeast Asia, mainly Bangladesh, India, Indonesia, Malaysia, Myanmar, Thailand and Sri Lanka, but is naturalised and cultivated in many countries in Africa and the Caribbean. Myanmar's teak forests account for nearly half of the world's naturally occurring teak. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fungal Tree Pathogens And Diseases
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] |

Root Vegetable Diseases
In vascular plants, the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial or aerating, that is, growing up above the ground or especially above water. Function The major functions of roots are absorption of water, plant nutrition and anchoring of the plant body to the ground. Anatomy Root morphology is divided into four zones: the root cap, the apical meristem, the elongation zone, and the hair. The root cap of new roots helps the root penetrate the soil. These root caps are sloughed off as the root goes deeper creating a slimy surface that provides lubrication. The apical meristem behind the root cap produces new root cells that elongate. Then, root hairs form that absorb water and mineral nutrients from the soil. The first root in seed producing plants is the r ...

Non-food Crop Diseases
A nonfood crop, also known as industrial crop, is a crop grown to produce goods for manufacturing, for example fibre for clothing, rather than food for consumption. Purpose Industrial crops is a designation given to an enterprise that attempts to raise farm sector income, and provide economic development activities for rural areas. Industrial crops also attempt to provide products that can be used as substitutes for imports from other nations. Diversity The range of crops with non-food uses is broad, but includes traditional arable crops like wheat, as well as less conventional crops like hemp and Miscanthus. Products made from non-food crops can be categorised by function: See also * Biofuel * Bioplastics * Biopolymer * Cash crops * Cellulosic biofuel * Energy crop * Food vs fuel * Helix of sustainability * Intensive crop farming * National Non-Food Crops Centre * Renewable Energy Renewable energy is energy that is collected from renewable resources that are ...
