The impact of pesticides consists of the effects of pesticides on non-target species. Pesticides are chemical preparations used to kill fungal or animal pests. Other problems emerge from poor production, transport and storage practices.

Pesticides can be grouped according to the types of pests which they kill: Insecticides - insects Herbicides - plants Rodenticides - rodents rats and mice Bactericides - bacteria Fungicides - fungi Larvicides - larvae Fig. For example, they can be grouped according to the chemicals in them or to the method of application. Insecticides kill insects by getting inside their bodies where they then act as poison. There are three different ways insecticides can get into an insect body. In insects, the skin is called the cuticle. Insecticides of this kind are called contact poisons. Dermal entry can happen when: aerosol spray droplets hit the insect insects walk over and thereby come into contact with powder or granule forms of insecticide Fig.

Cultural methods of pest control consist of regular farm operations in such a way which either destroy the pests or prevent them from causing economic loss. The various cultural practices are as under. In this process regulatory rules framed by Govt. These are known as quarantine methods and are of two types i. Biological control of insect pests and diseases through biological means is most important component of IPM.

Pesticides are widely used in agricultural production to prevent or control pests, diseases, weeds, and other plant pathogens in an effort to reduce or eliminate yield losses and maintain high product quality. Although pesticides are developed through very strict regulation processes to function with reasonable certainty and minimal impact on human health and the environment, serious concerns have been raised about health risks resulting from occupational exposure and from residues in food and drinking water. Occupational exposure to pesticides often occurs in the case of agricultural workers in open fields and greenhouses, workers in the pesticide industry, and exterminators of house pests. Exposure of the general population to pesticides occurs primarily through eating food and drinking water contaminated with pesticide residues, whereas substantial exposure can also occur in or around the home.

Insecticide , any toxic substance that is used to kill insects. Such substances are used primarily to control pests that infest cultivated plants or to eliminate disease-carrying insects in specific areas. Insecticides can be classified in any of several ways, on the basis of their chemistry, their toxicological action, or their mode of penetration. In the latter scheme, they are classified according to whether they take effect upon ingestion stomach poisons , inhalation fumigants , or upon penetration of the body covering contact poisons. Most synthetic insecticides penetrate by all three of these pathways, however, and hence are better distinguished from each other by their basic chemistry. Besides the synthetics , some organic compounds occurring naturally in plants are useful insecticides, as are some inorganic compounds; some of these are permitted in organic farming applications.
The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others. Among these, organochlorine OC insecticides, used successfully in controlling a number of diseases, such as malaria and typhus, were banned or restricted after the s in most of the technologically advanced countries. The introduction of other synthetic insecticides — organophosphate OP insecticides in the s, carbamates in s and pyrethroids in s and the introduction of herbicides and fungicides in the s—s contributed greatly to pest control and agricultural output. Ideally a pesticide must be lethal to the targeted pests, but not to non-target species, including man. Unfortunately, this is not the case, so the controversy of use and abuse of pesticides has surfaced. The production of pesticides started in India in with the establishment of a plant for the production of BHC near Calcutta, and India is now the second largest manufacturer of pesticides in Asia after China and ranks twelfth globally Mathur,
