About Pesticides


Toxic residue types

Most toxic residue refers to pesticides that can be categorized in many groups. This can be according to types of effects like insecticides, herbicides, fungicides, nematocides for example. Categorizing them according to their formula results in:

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.
