pesticide

Toxicology An annihilator of ambient arachnids, antagonistic arthropods, abominable animacules or pugnacious plants–eg, fumigants, fungicides, herbicides, insecticides; most are toxic and potentially fatal, with high arsenical or organophosphate content, and store in adipose tissue, given their lipid solubility Types Organochlorines-eg, DDT, chlordane, mirex, organophosphates–eg, parathion, diazinon, carbamates–eg, Aldicarb, carbaryl, carbofuran, metals–eg, copper, tributyl-tin oxide, pyrethroids–eg, permethrin, cypermethrin, etc–eg, 2,4-D, atrazine, paraquat. See Intermediate syndrome, Organophosphate pesticide.

pes·ti·cide

(pes'ti-sīd)
General term for an agent that destroys fungi, insects, rodents, or any other pest.

pesticide

any agent that causes the death of a pest. The general definition is usually restricted to chemicals with pesticidal properties, such as herbicides, insecticides, acaricides and fungicides. Pesticide application can produce many problems, for example:
  1. (a) destruction of organisms useful to man (‘nontarget’ species).
  2. (b) directly harmful effects to man if used incorrectly
  3. (c) accumulation and concentration in food chains leading to toxicity in animals at a higher TROPHIC LEVEL.

pesticide

a poison used to destroy pests of any sort. See arsenical, carbamates, chlorinated hydrocarbons, organophosphorus compound, pyrethroids.

pesticide poisoning
pesticides are selective poisons chosen for use because of their relative safety for humans and animals. It is likely that they will poison these species if they are used in sufficient quantity or in special circumstances, for example when the water intake of the subject animals is limited.
pesticide resistance
continued use of a single agent, or a group of closely allied agents, can cause selective survival of insects with innate tolerance of the agent and lead to the development of a resistant population.
pesticide tissue residues
some pesticides have had to be withdrawn from use because of their persistence in the tissues of animals including humans. The passage of the agent in the milk of the animal is a comparable problem.
