Pesticides In New Zealand
There is a high use of pesticides in New Zealand due predominantly to the large agricultural industry. Pesticides 1080 Sodium fluoroacetate, commonly known as 1080, is used in New Zealand to control animal pests, specifically the possum which threatens biodiversity and carries tuberculosus. Hunters fear that 1080 impacts on game animals, and some environmentalists have concerns about 1080 killing the very native fauna it is meant to save, and pollution of drinking water reservoirs with 1080 baits and poisoned animals. 2,4,5-T Manufacture of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) ceased in New Zealand in 1987 and it is no longer sold in New Zealand. 2,4-D 2,4-Dichlorophenoxyacetic acid (2,4-D) is used in New Zealand and the Pesticides Board has decided not to prohibit the use of the chemical. DDT DDT was used extensively for agricultural use in the 1950s and 1960s to control grass grub and porina moth. It was also used on lawns and for market gardens. Some 500 t ...

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 diseas ...

Methyl Bromide
Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H3 Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. It has a tetrahedral shape and it is a recognized ozone-depleting chemical. It was used extensively as a pesticide until being phased out by most countries in the early 2000s. Occurrence and manufacture Bromomethane originates from both natural and human sources. In the ocean, marine organisms are estimated to produce 56,000 tonnes annually. It is also produced in small quantities by certain terrestrial plants, such as members of the family Brassicaceae. It is manufactured for agricultural and industrial use by treating methanol with bromine in the presence of sulfur or hydrogen sulfide: :6 CH3OH + 3 Br2 + S → 6 CH3Br + 2 H2O + H2SO4 Uses In 1999, an estimated 71,500 tonnes of synthetic methyl bromide were used annually worldwide. 97% of this estimate was used for fumigation purposes, ...

Pesticide Residues In New Zealand
Pesticide residues are of concern in New Zealand and foods are regularly checked to see if they are within set limits. Food Standards Australia New Zealand develops the standards for levels of pesticide residues in foods through a consultation process and the New Zealand Food Safety Authority publishes the maximum limits of pesticide residues for foods produced in New Zealand. Pesticide residues tested in 1997 were generally low and thought to pose no detectable threat to health. More recent research shows a link between pesticides and Parkinson's disease, and on the foetus. The Soil & Health Association of New Zealand and the Pesticide Action Network Aotearoa New Zealand claim that the 2010 results are the worst ever. Some of the results include: * Pesticide residues found in 94% of targeted fruit and vegetable samples * Prohibited endosulfan in 11 of 23 cucumber samples * Dangerous fungicide exceeding allowable levels in 9 out of 24 Pak choi samples * 18 different pesticides ...

Gorse In New Zealand
Gorse (''Ulex europaeus'') was introduced to New Zealand in the early stages of European settlement. It is now a major invasive plant species with millions of dollars spent on its control. Introduction to New Zealand Introduced from Western Europe in the very early stages of European settlement, it was recorded by Charles Darwin during his voyage through New Zealand waters in 1835 as growing in hedges in the Bay of Islands. Its spread and development as a weed in New Zealand's temperate climate was rapid, but settlers failed to recognise the threat; gorse seed continued to be imported and plantings deliberately established into the 1900s. Uses Gorse has been used for hedges and windbreaks on the Canterbury Plains since the 1850s. These windbreaks have a combined length of 300,000 kilometres. Gorse has been found to form a useful nursery for many species for native bush regeneration. When young, gorse bushes are very dense. As they grow older, they become 'leggy', and provide ...

Environmental Impact Of Pesticides
The environmental effects of pesticides describe the broad series of consequences of using pesticides. The unintended consequences of pesticides is one of the main drivers of the negative impact of modern industrial agriculture on the environment. Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Other agrochemicals, such as fertilizers, can also have negative effects on the environment. The negative effects of pesticides are not just in the area of application. Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas. Other problems emerge from poor production, transport, storage and disposal practices.Tashkent (199 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environment Of New Zealand
The environment of New Zealand is characterised by an endemic flora and fauna which has evolved in near isolation from the rest of the world. The main islands of New Zealand span two biomes, temperate and subtropical, complicated by large mountainous areas above the tree line.Walter, H. & Breckle, S-W. (2002). ''Walter's Vegetation of the Earth: The Ecological Systems of the Geo-Biosphere''. New York: Springer-Verlag, p. 86 There are also New Zealand Subantarctic Islands, numerous smaller islands which extend into the subantarctic. The prevailing weather systems bring significantly more rain to the west of the country. New Zealand's territorial waters cover a much larger area than its landmass and extend over the continental shelf and abyssal plateau in the South Pacific Ocean, Tasman Sea and Southern ocean. Historically having an isolated and endemic ecosystem far into modernity, the arrival of Polynesians about 1300 AD and then later European settlers began to have significa ...

Agriculture In New Zealand
In New Zealand, agriculture is the largest sector of the tradable economy. The country exported NZ$46.4 billion worth of agricultural products (raw and manufactured) in the 12 months to June 2019, 79.6% of the country's total exported goods. The agriculture, forestry and fisheries sector directly contributed $12.653 billion (or 5.1%) of the national GDP in the 12 months to September 2020, and employed 143,000 people, 5.9% of New Zealand's workforce, as of the 2018 census. New Zealand is unique in being the only developed country to be totally exposed to the international markets since subsidies, tax concessions and price supports for the agricultural sector were removed in the 1980s. However, as of 2017, the New Zealand Government still provides state investment in infrastructure which supports agriculture. Pastoral farming is the major land use but there are increases in land area devoted to horticulture. New Zealand is a member of the Cairns Group, which is seeking to hav ...

Gypsy Moth
''Lymantria dispar'', also known as the gypsy moth or the spongy moth, is a species of moth in the family Erebidae. ''Lymantria dispar'' is subdivided into several subspecies, with subspecies such as ''L. d. dispar'' and ''L. d. japonica'' being clearly identifiable without ambiguity. ''Lymantria dispar'' has been introduced to several continents and is now found in Europe, Africa, Asia, North America and South America. The polyphagous larvae live on a variety of deciduous and coniferous trees and can cause severe damage in years of mass reproduction. Due to these features, ''Lymantria dispar'' is listed among the world's 100 worst invasive alien species. Etymology The name “gypsy moth” does not have conclusive origins, however it has been in use since 1908. Moths of the subfamily Lymantriinae are commonly called tussock moths due to the tussock-like tufts of hair on the caterpillars.The Gypsy Moth: Research Toward Integrated Pest Management, United States Department o ...

Hamilton, New Zealand
Hamilton ( mi, Kirikiriroa) is an inland city in the North Island of New Zealand. Located on the banks of the Waikato River, it is the seat and most populous city of the Waikato region. With a territorial population of , it is the country's fourth most-populous city. Encompassing a land area of about , Hamilton is part of the wider Hamilton Urban Area, which also encompasses the nearby towns of Ngāruawāhia, Te Awamutu and Cambridge. In 2020, Hamilton was awarded the title of most beautiful large city in New Zealand. The area now covered by the city was originally the site of several Māori villages, including Kirikiriroa, from which the city takes its Māori name. By the time English settlers arrived, most of these villages, which sat beside the Waikato River, were abandoned as a result of the Invasion of Waikato and land confiscation (''Raupatu'') by the Crown. Initially an agricultural service centre, Hamilton now has a diverse economy and is the third fastest growin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
