Coumaphos is a nonvolatile, fat-soluble phosphorothioate with ectoparasiticide properties: it kills insects and mites. It is well known by a variety of brand names as a dip or wash, used on farm and domestic animals to control ticks, mites, flies and fleas.
A United States Environmental Protection Agency report identified profenofos as toxic to birds, small mammals, bees, fish, and aquatic invertebrates, noting several fish kill incidents in which profenofos exposure, primarily due to runoff, was implicated as a probable cause.
Toxicity labels [1] viz; red label, yellow label, blue label and green label are mandatory labels employed on pesticide containers in India identifying the level of toxicity (that is, the toxicity class) of the contained pesticide. [1] [2] [3] The schemes follows from the Insecticides Act of 1968 [1] and the Insecticides Rules of 1971.
Terbufos, also known as S-((tert-butylthio)methyl) O,O-diethyl phosphorodithioate, [17] is a compound classified as an organophosphate.Terbufos consists of a central phosphorus atom, surrounded by four different groups.
The Environmental Protection Agency has determined that exposure levels from eating crops treated with Naled are below the level of concern. [5] With higher exposures, however, naled can cause cholinesterase inhibition in humans, which in turn can overstimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures, respiratory paralysis and death.

Because of its high toxicity to aquatic organisms, bifenthrin is classified as a restricted-use pesticide, meaning it may only be sold to certified pesticide applicators. However, the EPA allows lower concentrations of bifenthrin to be sold to the general public. [citation needed]
BPUs have a good mammalian tox profile. Diflubenzuron is considered to be of very low acute toxicity, and is approved by the WHO for treatment of drinking water as a mosquito larvicide. [8] BPUs have low acute toxicity against bees, low to moderate toxicity to fish, but high toxicity to aquatic invertebrates and crustaceans. [1]
It is very toxic both for target organisms and for mammals including humans. It inhibits acetylcholinesterase and butyrylcholinesterase. [3] Phorate is most commonly applied in granular form. It is non-biocumulative and has no residual action. But some metabolites may persist in soil. It also damages some seeds. [3]
