The use of pesticides on or around Dogs will hurt their health and much care should be taken when using them. part 2
• Allethrin. This pesticide was the first of the pyrethroids widely produced as an insecticide (Vijverberg et al., 1990). This synthetic compound is used almost exclusively in homes and gardens for address of flies and mosquitoes. chemicals containing allethrin were slightly toxic category III chemicals and bear the signal word "caution" on the product label. However, containers of technical grade D-trans-allethrin bear the signal word "warning". Allethrin is used in many commercial products and is available as mosquito coils, mats, oil formulations, and as an aerosol spray. Research has indicated that dogs exposed continuously to D-allethrin were diagnosed with liver problems (World Health Organization, 1989).
• Bendiocarb. This compound is an insecticidal carbamate that is used to address mosquitoes, flies, wasps, ants, cockroaches, fleas, ticks, and other pests in homes. Most formulations of bendiocarb are classified as GUP, but a few formulations are classified as Restricted Use pesticides (RUP), which can be purchased and used only by certified applicators. Bendiocarb is a moderately toxic category II chemical and carries the signal word "warning". Commercial poisons containing bendiocarb could be formulated as dusts, granules, ultra-low volume sprays, and as wettable powders. Bendiocarb is absorbed as a result of all the normal routes of exposure, but it is More often than not excreted rapidly and does not accumulate in mammalian tissue. Signs involved with acute toxicity of carbamates in mammals are excessive salivation, chest discomfort, muscle tremors, and rarely death. Like other carbamate insecticides, bendiocarb is a reversible inhibitor of cholinesterase, an enzyme found in the liver, pancreas, heart, serum, and the white matter of brain. True cholinesterase catalyzes the hydrolysis of acetylcholine (a neurotransmitter) to choline (an amino alcohol) and acetate.
• DCPA. This phthalate compound, also called chlorthal or chlorthal-dimethyl, is a pre-emergent herbicide used on annual grasses and annual broad-leaf weeds in vegetable crops. About 20% of the use of this compound in the United States is for homes and gardens. DCPA is classified as a GUP and is practically a nontoxic category IV chemical that bears the signal word "caution". Commercial products containing DCPA can be formulated as wettable powders, granules, or as suspension concentrates. Although the compound has a very low toxicity to mammals, research has indicated that dogs exposed continuously to DCPA experienced adverse effects in the liver (United States Environmental Protection Agency (EPA), 1988).
• Diazinon. This product is a nonsystemic organophosphate insecticide used to manage fleas, ants, and cockroaches in residential buildings, and sucking and leaf-eating insects on home gardens. Diazinon is classified as a RUP, which can be purchased and used only by a professional pest address operator. Depending on the formulation, it is a moderately toxic category II or slightly toxic category III chemical. poisons containing diazinon bear the signal word "warning" or "caution". This insecticidal organophosphate compound is used in many commercial products and is available in dust, granules, seed dressings, wettable powder, and emulsifiable solution formulations. In mammals, diazinon is metabolized and excreted with the help of the urine and feces very rapidly. The toxic effects of the compound could be due to the inhibition of acetylcholinesterase, an essential nervous system enzyme.
• Malathion. This compound is a nonsystemic, wide-spectrum organophosphate insecticide suited for the control of sucking and chewing insects on fruits and vegetables. Malathion is also used to control mosquitoes, flies, household insects, and animal ectoparasites.
