picture info	Plant Pathogen Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Douglas-fir The Douglas fir (''Pseudotsuga menziesii'') is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (''P. menziesii'' var. ''menziesii''), Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and Mexican Douglas-fir (''P. menziesii'' var. ''lindleyana''). Despite its common names, it is not a true fir (genus ''Abies''), spruce (genus '' Picea''), or pine (genus ''Pinus''). It is also not a hemlock; the genus name ''Pseudotsuga'' means "false hemlock". Description Douglas-firs are medium-size to extremely large evergreen trees, tall (although only ''Pseudotsuga menziesii var. menziesii'', common name coast Douglas-firs, reach heights near 100 m) and commonly reach in diameter, although trees with diameters of almost exist. The largest coast Douglas-firs regularly live over 500 years, with the olde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	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]
	Diaporthales Diaporthales is an order of sac fungi. Wijayawardene et al. in 2020 added a number of name families to the order. Diaporthales includes a number of plant pathogenic fungi, the most notorious of which is ''Cryphonectria parasitica'' (Murrill) Barr, the chestnut blight fungus that altered the landscape of eastern North America. Other diseases caused by members of this order include stem canker of soybeans ('' Diaporthe phaseolorum'' (Cooke & Ellis) Sacc. and its varieties), stem-end rot of citrus fruits ('' Diaporthe citri'' F.A. Wolf), and peach canker disease (''Phomopsis amygdali'' Del.). Some species produce secondary metabolites that result in toxicosis of animals such as lupinosis of sheep (''Diaporthe toxica'' P.M. Williamson et al.). A number of asexually reproducing plant pathogenic fungi also belong in the Diaporthales, such ''Greeneria uvicola'' (Berk. & Curt.) Punith., cause of bitter rot of grape, and ''Discula destructiva'' Redlin, cause of dogwood anthracnose, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
