A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling any pest.

Mode of action of pesticides is not specific to one species. Hence they often kill or harm organisms other than pests, including humans. The WHO estimates that there are 3 million cases of pesticide poisoning each year and up to 2,20, deaths primarily in developing countries. Routes of exposure Wind Inhalation Dermal Penetration Absorbed into the soil and then taken up by other organisms Contaminates ground water May be absorbed by the plants May flow into other water sources 6.

Inhalation of spray mist or dust from these pesticides may cause throat irritation, sneezing, and coughing. Chronic exposures to lower concentrations of fungicides can cause adverse health effects. Herbicides Many can be dermal irritants since they are often strong acids, amines, esters, and phenols. Inhalation of spray mist may cause coughing and a burning sensation in the nasal passages and chest.

Prolonged inhalation sometimes causes dizziness. Ingestion will usually cause vomiting, a burning sensation in the stomach, diarrhea, and muscle twitching. Few Herbicides are: 2,4- dichlorophenoxyacetic acid, Glyphosate, Propanil, Atrazine Insecticides Insecticides cause the greatest number of pesticide poisonings.

Acute exposure to organophosphate and carbamate insecticides. Organophosphates and carbamates inhibit the enzyme cholinesterase, causing a disruption of the nervous system. All life forms with cholinesterase in their nervous system, such as insects, fish, birds, humans, and other mammals, can be poisoned by these chemicals.

Organophosphate insecticides include diazinon, dimethoate, disulfoton, methyl parathion, and ethyl parathion. The carbamate compounds include carbaryl, carbofuran, methomyl, and oxamyl. Major health disorders: Cancer Neurodevelopment problems, childrens IQ, behavioral disorders Birth defects Foetal Growth: Measures of foetal growth commonly include birth weight, head circumference, and intrauterine growth restriction.

Respiratory Disorders Metabolic disorders obesity, diabetes, metabolic disease Remidies: Switching to Organic Farming Substitution: Replacement of hazardous pesticides by less hazardous alternatives Integrated Pest Management Create awareness among the people Conclusion: Pesticide contamination a great risk to the environment and organisms Action is to be taken at a regulatory level to recognise the problems of ongoing low dose exposure to mixtures of pesticides,.

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.

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. Regarding the adverse effects on the environment water, soil and air contamination from leaching, runoff, and spray drift, as well as the detrimental effects on wildlife, fish, plants, and other non-target organisms , many of these effects depend on the toxicity of the pesticide, the measures taken during its application, the dosage applied, the adsorption on soil colloids, the weather conditions prevailing after application, and how long the pesticide persists in the environment. Therefore, the risk assessment of the impact of pesticides either on human health or on the environment is not an easy and particularly accurate process because of differences in the periods and levels of exposure, the types of pesticides used regarding toxicity and persistence , and the environmental characteristics of the areas where pesticides are usually applied. Also, the number of the criteria used and the method of their implementation to assess the adverse effects of pesticides on human health could affect risk assessment and would possibly affect the characterization of the already approved pesticides and the approval of the new compounds in the near future.

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.

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.

Extension Pesticide Program. Host - A plant or animal on or in which a pest lives. Juvenile hormones - Natural insect chemicals that keep the earlier stages of an insect from changing into the normal adult form. Labeling - The pesticide product label and other accompanying materials that contain directions that pesticide users are legally required to follow Mycoplasmas - The smallest known living organisms that can reproduce and exist apart from other living organisms. Nematodes - Small, usually microscopic, eel-like roundworms.

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.

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. Each pesticide or pesticide class comes with a specific set of environmental concerns.
