The 1,3- isomer is uncommon because it is a meta- compound, while chlorine, like all halogens, is an ortho/para-director in terms of electrophilic aromatic substitution. It is mainly used as a precursor to 1,2-dichloro-4-nitrobenzene , an intermediate in the synthesis of agrochemicals . [ 5 ]

Bifenthrin is an effectively used insecticide, but the risk is high of it working only for a short time. Mosquitoes can develop a resistance to it, as well. [8] Aquatic life. Bifenthrin is hardly soluble in water, so nearly all bifenthrin will stay in the sediment, but it is very harmful to aquatic life.

The 2024 IRAC poster of insecticide modes of action includes the majority of chemicals listed below. [5] The pesticide manual provides much information on pesticides. [6] [7] Many of the insecticides in the list are not in use.
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.
