The microorganism was classified as a new species of actinomycete. Streptomyces avermitilis. Its anthelmintic activity was shown to reside in 8 closely related macrocyclic lactones, named avermectins, which were also found to possess activity against free-living and parasitic arthropods. One of the natural components, avermectin is now being evaluated as a pesticide for the control of mites of citrus and cotton crops and control of the Red Imported Fire Ant. A chemical derivative, 22,23-dihydroavermectin or ivermectin, has been developed as an antiparasitic agent. It is being marketed for use in cattle, horses and sheep and is expected to become available for swine and dogs. [Pg.5]

The impact of pesticides on water quality in organic systems has rarely been studied (Stock-dale et al. 2001). Again, however, most of the water contamination comes from herbicides used in conventional farming. There is some debate about the disposal of sheep dip and the relative risks of pyrethroids versus organophosphates. Organic farmers only use the former and they are potentially more damaging to aquatic habitats. [Pg.274]

Arsenic trioxide finds major use in the preparation of other compounds, notably those used in agricultural applications, The compounds monosodium methylarsonate. disodium methylarsonate, methane arsenic acid (cacodylic acid) are used for weed control, while arsenic acid, H3ASO4, is used as a desiccant for the defoliation of cotton crops, Other compounds once widely used in agriculture are calcium arsenate for control of boll weevils, lead arsenate as a pesticide for fruit crops, and sodium arsenite as a herbicide and for cattle and sheep dip. In some areas, arsenilic acid has been used as a feed additive for swine and poultry. Restrictions on these compounds vary from one country and region to the next. [Pg.148]

Pollution with arsenic can also be due to human, industrial activity, and most of the arsenic in the atmosphere is from the burning of fossil fuels. Arsenic has been used in fruit sprays, insecticides (lead arsenate), weedkillers (sodium or copper arsenite), rat poison, sheep dips, fly papers, wood preservative, and in glass-making. It is now also used in the semiconductor industry. Apparently, it was used as a pesticide by the Chinese centuries ago. Most of the arsenic used commercially in the world is probably contained in various pesticides. This inevitably leads to contamination of the environment. [Pg.119]

The pesticide has also been used to control exoparasites on livestock (cattle, sheep, and goats) [20]. Toxaphene is highly toxic to fish. For a short period in the 1960s, it was used as a piscicide to eliminate undesired fish species in lakes prior to the release of commercially attractive fish species. Saleh reported about 817 registered products containing toxaphene in a concentration of 1 % to 80% [3]. Toxaphene was marketed as emulsifiable concentrates, powders, granules, and baits [3]. [Pg.240]

The genetic modification of livestock stems from a desire to enhance growth, increase production of high protein milk and cheese, facilitate biomedical research, as well as potentially protect against incidental toxicity via exposure to pesticides that may be associated with food crops. Animal genomes that have been successfully modified include sheep, pigs, cows, rabbits, and chickens. Two key research areas applied to livestock are discussed below. [Pg.1245]
