Pest control means management of a species creating problems for human beings directly or indirectly, since it is considered to be harmful to an individual’s health, the economy or the ecology. Pest management is at least as old as agriculture as it was necessary to keep crops free from unwanted animal.
Chemical control dates back 4500 years, with the Sumerians using Sulphur compounds as insecticides. In India the Rig Veda, which is about 4000 years old mentions the use of poisonous plants for pest control. But chemical management became widespread with industrialization and mechanization of agriculture in 18th and 19th century, and the introduction of insecticides Pyrethrum and Derris Today chemical pest control is the dominant type of pest control. But its aftereffects have led people to think about alternatives in the form of traditional and biological pest control.
The chemical agents include herbicides, insecticides and fungicides.
Long lasting synthetic compounds which affect the nervous system of insects on contact are applied as insecticides. Examples of most effective insecticides are the chlorinated hydrocarbons DDT, Chlordane and Toxaphene, even though DDT has been banned. Organophosphate insecticides include Malathiom, Parathion and Dimethoate. 2, 4- dichlorophenoxyacetic acid is the most effective herbicide, used to kill broad leaved weeds.
The disadvantage of using pesticides is that though they are valuable for agriculture, they can cause serious harm. Hence more and more people are shifting to organic and biological pest control measures. I would recommend you to find more lots of information about the pest control methods and safety measures before you start something. This information can be found through many sources. There are many directories which provide free of cost information about pest control and other valuable topics. Enough research can help you a lot in making the right choice. You should always be careful with chemical methods of pest control because they are very useful but can cause lot of problems.
