Insecticides are chemical agents used to control pests. Including organic pesticides (organochlorine, organophosphorus, organic sulfur preparations and carbamates and pyrethroids), inorganic insecticides (inorganic arsenic, inorganic fluorine, inorganic sulfur preparations), plant insecticides, minerals Oil insecticides, microbial pesticides.
