 Effective against borers & Sucking pests.
 LD50 : 80-110 mg/Kg
c) Organophosphates
• OP group of insecticides came to lime light during 2nd world war.
• Insecticidal action of OP compounds was discovered by Gerhard schrader in 1942 in Germany.
• TEPP (Tetra Ethyl Pyro Phosphate), Parathion & Schraden-1st Systemic insecticides.
• Most effective and low residual effect.
• Important insecticides :
Malathion, Methyl parathion, Diazion, Dichlorovas(DDVP),
Quinalphos, Chloropyriphos, Phosphamidon, Dimethoate,
Profenophos, Phorate etc.
Classification of OP insecticides
 Phosphohalides & Cyanides : Ex : Sarine, Tabum, Soman.

 Phosphorothionate : Ex : Chloropyriphos, Quinalphos, Fenitrothion. Diazinon etc.
 Phosphoroamidate : Ex : Acephate, TEPP, Schradan.
 Among OP Dichlorovas shows a fumigant action.
 Chloropyriphos used against termite.
 Phorate widely used as Granular insecticides.
 Malathion- Safest insecticides.
Carbamate insecticides
 Carbamate insecticides are synthetic derivatives of Physostigmine commonly known as Eserine.
 it is a alkaloid extracted from the seeds of Calabar bean.
 They have systemic and contact action.
Carbamate insecticides are classified into
 Hetrocyclic carbamates : Ex- Isolan, Pyrolan.
 Napthyl carbamates : Ex- Carbaryl.
 Phenyl carbamates : Ex- Carbofuran.
 Oxime carbamates : Ex- Aldicarb, Methomyl.
• Widely used carbamate insecticide against borers- Carbofuran.
• Carbamate insecticide used against cockroach, flies, mosquitoes- Propoxar.
• Wide spectrum C. insecticide used against cotton pests- Carbaryl.
• Insecticide of Carbamate group which is highly toxic to mammals- Aldicarb.
• Carbamate insecticide which is used to control nematodes- Carbofuran.
SYNTHETIC PYRETHROIDES
 These are synthetic derivatives of natural pyrethrins.
 The main commercial source of pyrethrum is the mature flower of chrysanthemum .
 The high quality flowers contain up to 4 mg of pyrithrins.
 These are lipophilic compounds.
