types of insecticides with examples

Chlorinated hydrocarbons The chlorinated hydrocarbons were developed beginning in the 1940s after the discovery (1939) of the insecticidal properties of DDT. Types of Pesticides • Bactericides for the control of bacteria • Herbicides for the control of weeds • Fungicides for the control of fungi • Insecticides for the control of insects - these can be Ovicides, Larvicides or Adulticides • Miticides for the control of mites • Nematicides for the control of worms • For this discovery, he was awarded the 1948 Nobel Prize for Physiology or Medicine. Insecticides represent a major area of emphasis. Instead of using chemical insecticides to avoid crop damage caused by insects, there are many alternative options available now that can protect farmers from major economic losses. Toxins from Saccharopolyspora spinosa are isolated from fermentations and sold as Spinosad. It is sprayed on plants or trees in a powdered form to act as a physical barrier between pests and the … Insecticides are used in agriculture, medicine, industry and by consumers. - One of the famous and basic classifications of insecticide is based on mode of entry (it means the way by which insecticide entry into the body of organism which are mostly insects).

[25] This runoff and percolation of insecticides can effect the quality of water sources, harming the natural ecology and thus, indirectly effect human populations through biomagnification and bioaccumulation. Contact insecticides are toxic to insects upon direct contact. Pesticides that are related because they address the same type of pests include: Algicides. The Main Pesticide Types. This classification is given below with detail of each group, 1. For example, they can be grouped according to the chemicals in them or to the method of application. Types of Pesticides.

A number of organochlorine pesticides have been banned from most uses worldwide. Solid bait and liquid insecticides, especially if improperly applied in a location, get moved by water flow. A more recent type of IGR is the ecdysone agonist tebufenozide (MIMIC), which is used in forestry and other applications for control of caterpillars, which are far more sensitive to its hormonal effects than other insect orders.
