Information @ a Glance

Contents on the CD Rom

  • Malathion is an organophosphate parasympathomimetic which binds irreversibly to cholinesterase.
  • Malathion is a nonsystemic, wide-spectrum organophosphate insecticide.
  • Malathion is slightly toxic via the oral route.
  • Malathion can also be found in products that are used on pets to control ticks and fleas.
  • Trade names for products containing malathion include Celthion, Cythion, Dielathion, El 4049, Emmaton, Exathios, Fyfanon and Hilthion,
    Karbofos and Maltox.
  • Malathion present in untreated water is converted to malaoxon during the chlorination phase of water treatment, so malathion should not be used in waters that may be used as a source for drinking water, or any upstream waters.
  • Malathion works by attacking the nervous system; it is essentially a nerve poison.
  • The “disappearance method” was applied by measuring malathion concentrations in the water before and after human subject exposure to the water for various periods of time. Malathion was measured using Gas Chromatography.
  • The extent to which pesticide residues may be removed from treated produce by washing is influenced by a variety of factors such as the chemical properties of the pesticide, the nature ofthe commodity, the length of time that the residue has been on the commodity's surface, and the
    formulation in which the pesticide has been applied.
  • In the open environment, malathion degrades rapidly by hydrolysis, biodegradation and photolysis, roughly in that order of importance.
  • Malathion in water may be determined by extracting into dichloromethane, drying the extract, redissolving in hexane and analysing by gas–liquid
    chromatography, phosphorus mode.
  • Malathion inhibits the proper functioning of the nervous system of the adult mosquito.
  • Malathion produced detectable mutations in three different types of cultured human cells, including white blood cells and lymph cells.
  • Malathion is mutagenic, carcinogenic, has been implicated in vision loss, kidney damage, and lung damage.
  • Malathion is the most common agent used in Canada for the control of adult mosquitoes by ultra low volume (ULV) application.
  • Two types of exposure assessments were conducted for malathion used to control larval mosquitoes and adult mosquitoes resting on vegetation.
  • While Malathion is used for miscellaneous insect pests (katydids, whiteflies, aphids) at fairly low use rates, it fills an important need for soft scale
    insects in certain situations.
  • Gas and thin-layer chromatography and infrared spectroscopy confirmed malathion to be degraded via malathion- monocarboxylic acid to the
    dicarboxylic acid and then to various phosphothionates.
  • PFF is a newly recorded species of fruit flies. PFF control in Egypt is based primarily on applications of organophosphate insecticides, especially malathion, mixed with protein baits using bait application technique.
  • Malathion pesticide is widely used and has been reported to damage mice spermatogenesis.
  • Malathion was evaluated in two districts namely Hardwar (Uttaranchal) and Kheda (Gujarat) and was found effective in reducing An. culicifacies
    population. In other districts in Gujarat variable level of malathion susceptibility was observed.
  • Approvals of the active constituent maldison are being reconsidered because of concerns that the presence of certain impurities (specified in the
    minimum compositional standard – MCS) may be harmful to human beings.
