1.) Organochlorine
compounds or chlorinated hydrocarbon such as DDT are chemicals used
in the early days of agriculture, but never since the discovery of
the slow rate at which these chemicals decomposed, the chemical has
been banned.
 |
ĠDDT(Dichloro
Diphenyl Trichloroethane) |
2.) Organophosphorous compounds such as parathion methyl, parathion
monocrotophos for example. These chemicals are widely used and highly
toxic, but decomposes relatively quickly.
 |
Diethyl 4-nitrophenyl phosphorothionate (PARATHION) |
3.) Carbamates group such as Carbaryl or Sevin 85, carbofluoraen
or fluradarn, methomyl for example. Carbaryl is a very common chemical
that is highly toxic but decomposes relatively quickly.
 |
1-Naphthyl methyl carbamate |
4.) Synthetic Pyrethroids such as Sypermytrin Phenvarilate for example.
These chemicals are reactive but not very poisonous to warm-blooded
animals, decomposes quickly and widely used just like group 2 and
3.
