Conifer Release
Conifer release is a term used in forest management circles to denote selective silvicide and herbicide use, in order to promote conifers at the expense of alternate species. An Oregon State University Extension Service specialist wrote in 2014 that: History Weyerhauser used Glyphosate as early as 1979 for its conifer release programme. Scientists noted in 1997 that the below- and near-ground microclimates were affected by conifer release treatments. Scientists at the Lakehead University used Vision (a trade-mark of Monsanto) in 1998 to suppress '' Vaccinium'' blueberry production and hence to promote conifer release in a jack pine plantation.

Forest Management
Forest management is a branch of forestry concerned with overall administrative, legal, economic, and social aspects, as well as scientific and technical aspects, such as silviculture, protection, and forest regulation. This includes management for timber, aesthetics, recreation, urban values, water, wildlife, inland and nearshore fisheries, wood products, plant genetic resources, and other forest resource values. Management objectives can be for conservation, utilisation, or a mixture of the two. Techniques include timber extraction, planting and replanting of different species, building and maintenance of roads and pathways through forests, and preventing fire. Definition The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products ...

Fosamine Ammonium
Herbicides (, ), also commonly known as weedkillers, are substances used to control undesired plants, also known as weeds.EPA. February 201Pesticides Industry. Sales and Usage 2006 and 2007: Market Estimates. Summary in press releasMain page for EPA reports on pesticide use ihere Selective herbicides control specific weed species, while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes called total weedkillers in commercial products) can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact. Apart from selective/non-selective, other important distinctions include ''persistence'' (also known as ''residual action'': how long the product stays in place and remains active), ''means of uptake'' (whether it is absorbed by above-ground foliage only, through the roots, or by other means), and ''mechanism of action'' (how it works).

Dicamba
Dicamba (3,6-dichloro-2-methoxybenzoic acid) is a broad-spectrum herbicide first registered in 1967. Brand names for formulations of this herbicide include Dianat, Banvel, Diablo, Oracle and Vanquish. This chemical compound is a chlorinated derivative of ''o''-anisic acid. Around 2016, dicamba's use came under significant scrutiny due to its tendency to spread from treated fields into neighboring fields, causing damage. Use as an herbicide Dicamba kills annual and perennial broadleaf weeds. Its primary commercial applications are weed control for grain crops and turf areas. It is also used to control brush and bracken in pastures, as well as controlling legumes and cacti. In combination with a phenoxy herbicide or with other herbicides, dicamba can be used for weed control in range land and other noncrop areas (fence rows, roadways, and wastage). Dicamba is toxic to conifer species but is in general less toxic to grasses.Arnold P. Appleby, Franz Müller. "Weed Control, 2" ...

Atrazine
Atrazine is a chlorinated herbicide of the triazine class. It is used to prevent pre-emergence broadleaf weeds in crops such as maize (corn), soybean and sugarcane and on turf, such as golf courses and residential lawns. Atrazine's primary manufacturer is Syngenta and it is one of the most widely used herbicides in the United States, Canadian, and Australian agriculture. Its use was banned in the European Union in 2004, when the EU found groundwater levels exceeding the limits set by regulators, and Syngenta could not show that this could be prevented nor that these levels were safe.European Commission.2004/248/EC: Commission Decision of 10 March 2004 concerning the non-inclusion of atrazine in Annex I to Council Directive 91/414/EEC and the withdrawal of authorisations for plant protection products containing this active substance (Text with EEA relevance) (notified under document number C(2004) 731)Decision 2004/248/EC - Official Journal L 078, Decision 2004/248/EC.

Aminocarb
Animocarb (Matacil) is an organic chemical compound with the molecular formula C11 H16 N2 O2. It has a colorless or white crystal-like appearance and is most commonly used as an insecticide. History Aminocarb has been extensively used in eastern Canada since 1976 in order to control the spruce budworm. The fate of this chemical in the ecosystem and detection of aminocarb was studied by the use of two-dimensional thin-layer chromatography. The use of thin-layer chromatography helped isolate and identify the methyl amino, amino and hydroxymethyl analogues from the in vitro metabolism of aminocarb by liver homogenates from humans and rats. Production and uses Aminocarb is a carbamate insecticide widely used to protect cotton fields, crop fields, and forests from insect infestation. It helps in the control of aphids, soil mollusks, lepidopterous larvae, and other types of chewing insects. It is most commonly administered as an aerosol spray. Reactions Aminocarb can be ...

Amitrole
3-Amino-1,2,4-triazole (3-AT) is a heterocyclic organic compound that consists of a 1,2,4-triazole substituted with an amino group. 3-AT is a competitive inhibitor of the product of the HIS3 gene, imidazoleglycerol-phosphate dehydratase. Imidazoleglycerol-phosphate dehydratase is an enzyme catalyzing the sixth step of histidine production. 3-AT is also a nonselective systemic triazole herbicide used on nonfood croplands to control annual grasses and broadleaf and aquatic weeds. It is not used on food crops because of its carcinogenic properties. As an herbicide, it is known as ''aminotriazole'', ''amitrole'' or ''amitrol''. Amitrol was included in a biocide ban proposed by the Swedish Chemicals Agency and approved by the European Parliament on January 13, 2009. Applications in microbiology By applying 3-AT to a yeast cell culture which is dependent upon a plasmid containing HIS3 to produce histidine (i.e. its own HIS3 analogue is not present or nonfunctional), an increase ...

Pesticides
Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects. As an example, the fungus ''Alternaria solani'' is used to combat the aquatic weed ''Salvinia''. In general, a pesticide is a chemical (such as carbamate) or biological agent (such as a virus, bacterium, or fungus) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or ar ...

Jack Pine
Jack pine (''Pinus banksiana'') is an eastern North American pine. Its native range in Canada is east of the Rocky Mountains from the Mackenzie River in the Northwest Territories to Cape Breton Island in Nova Scotia, and the north-central and northeast of the United States from Minnesota to Maine, with the southernmost part of the range just into northwest Indiana and northwest Pennsylvania. It is also known as grey pine and scrub pine. In the far west of its range, ''Pinus banksiana'' hybridizes readily with the closely related lodgepole pine (''Pinus contorta''). The species epithet ''banksiana'' is after the English botanist Sir Joseph Banks. Description ''Pinus banksiana'' ranges from in height. Some jack pines are shrub-sized, due to poor growing conditions. They do not usually grow perfectly straight, resulting in an irregular shape similar to pitch pine (''Pinus rigida''). This pine often forms pure stands on sandy or rocky soil. It is fire-adapted to stand- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blueberry
Blueberries are a widely distributed and widespread group of perennial flowering plants with blue or purple berries. They are classified in the section ''Cyanococcus'' within the genus ''Vaccinium''. ''Vaccinium'' also includes cranberries, bilberries, huckleberries and Madeira blueberries. Commercial blueberries—both wild (lowbush) and cultivated (highbush)—are all native to North America. The highbush varieties were introduced into Europe during the 1930s. Blueberries are usually prostrate shrubs that can vary in size from to in height. In commercial production of blueberries, the species with small, pea-size berries growing on low-level bushes are known as "lowbush blueberries" (synonymous with "wild"), while the species with larger berries growing on taller, cultivated bushes are known as "highbush blueberries". Canada is the leading producer of lowbush blueberries, while the United States produces some 40% of the world supply of highbush blueberries. Origin and h ...
