Clopyralid
Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a selective herbicide used for control of broadleaf weeds, especially thistles and clovers. Clopyralid is in the picolinic acid family of herbicides, which also includes aminopyralid, picloram, triclopyr, and several less common herbicides.Staff, Virginia Tech Cooperative Extension. Revised May 14, 201Pyridine Herbicide Carryover: Causes and Precautions Accessed May 27, 2013 For control of creeping thistle, '' Cirsium arvense'', a noxious, perennial weed, clopyralid is one of the few effective herbicides available. It is particularly damaging to peas, tomatoes, and sunflowers, and can render potatoes, lettuce, and spinach inedible. It does not affect grasses (family Poaceae). Clopyralid is known for its ability to persist in dead plants and compost, and has accumulated to phytotoxic levels in finished compost in a few highly publicized cases. This first came to light in Washington, when during 2000 and 2001, residues of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbicide
Herbicides (, ), also commonly known as weed killers, 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 weed killers") kill plants indiscriminately. The combined effects of herbicides, nitrogen fertilizer, and improved cultivars has increased yields (per acre) of major crops by three to six times from 1900 to 2000. In the United States in 2012, about 91% of all herbicide usage, was determined by weight applied, in agriculture. In 2012, world pesticide expenditures totaled nearly US$24.7 billion; herbicides were about 44% of those sales and constituted the biggest portion, followed by insecticides, fungicides, and fumigants.

Compost
Compost is a mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical, and biological properties. It is commonly prepared by Decomposition, decomposing plant and food waste, recycling organic materials, and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes, and fungi. Compost improves soil fertility in gardens, landscaping, horticulture, urban agriculture, and organic farming, reducing dependency on commercial chemical fertilizers. The benefits of compost include providing nutrients to crops as fertilizer, acting as a soil conditioner, increasing the humus or Humic acids, humic acid contents of the soil, and introducing beneficial microbes that help to suppress pathogens in the soil and reduce soil-borne diseases. At the simplest level, composting requires gathering a mix of green waste (nitrogen-rich materials such as leaves, grass, and food scraps) and brown waste (woody ma ...

Chloropyridines
Chloropyridines are a group of aryl chlorides consisting of a pyridine ring with chlorine atoms as substituents. Chloropyridines include: *2-Chloropyridine *3-Chloropyridine *4-Chloropyridine *2,6-Dichloropyridine Production Direct halogenation of pyridine with chlorine gas above 270 °C gives a mixture of 2-chloropyridine and 2,6-dichloropyridine. 2- and 4-chloropyridine are prepared from the corresponding pyridinols using phosphoryl chloride. Uses Chloropyridines are important intermediates to pharmaceuticals and agrochemicals. A major use of 2-chloropyridine is the production of production of the fungicide pyrithione. Reaction of 4-chloropyridine with thioglycolic acid gives pyridylmercaptoacetic acid, a step in the production of cephalosporin antibiotics.

Broadleaf Weed
Broadleaf weeds are dicotyledonous weeds that may grow in lawns, gardens or yards. They can be easy to spot when growing among grasses. They are tougher than grassy monocot weeds, multiply with ease, and can be very hard to eradicate. Basic characteristics Broadleaf weeds can emerge annually, biennially, or perennially, making consistent management difficult. Perennial weeds are often very difficult to control as the weeds regenerate faster than they can be eradicated. Broadleaf weeds, as their name suggests, often have wide leaves and grow from a stem. Most broadleaf weeds develop clusters of blossoms or single flowers as they mature that can be considered undesirable. The roots of most broadleaf weeds are fibrous in nature. The roots can be thin, a large taproot, or a combination. Many broadleaf weeds spread through their seeds and rhizomes, although some only spread through seeds. Popular broadleaf weeds are chickweed, clover, dandelion, wild geranium, ivy, milkweed, plantai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poaceae
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials ( bamboo, thatch, and straw); oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thistle
Thistle is the common name of a group of flowering plants characterized by leaves with sharp spikes on the margins, mostly in the family Asteraceae. Prickles can also occur all over the planton the stem and on the flat parts of the leaves. These prickles protect the plant from herbivores. Typically, an involucre with a clasping shape similar to a cup or urn subtends each of a thistle's flower heads. The typically feathery pappus of a ripe thistle flower is known as thistle-down. The spininess varies considerably by species. For example, '' Cirsium heterophyllum'' has very soft spines while '' Cirsium spinosissimum'' is the opposite. Typically, species adapted to dry environments are more spiny. The term thistle is sometimes taken to mean precisely those plants in the tribe Cardueae (synonym: Cynareae), especially the genera '' Carduus'', '' Cirsium'', and '' Onopordum''. However, plants outside this tribe are sometimes also called thistles. Biennial thistles are partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
