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.
Advantages And Disadvantages of Pesticides
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, There has been a steady growth in the production of technical grade pesticides in India, from 5, metric tons in tometric tons in In —97 the demand for pesticides in terms of value was estimated to be around Rs. The pattern of pesticide usage in India is different from that for the world in general.
The use of herbicides and fungicides is correspondingly less heavy. The primary benefits are the consequences of the pesticides' effects — the direct gains expected from their use. For example the effect of killing caterpillars feeding on the crop brings the primary benefit of higher yields and better quality of cabbage. The three main effects result in 26 primary benefits ranging from protection of recreational turf to saved human lives.Volley multipartrequest library
The secondary benefits are the less immediate or less obvious benefits that result from the primary benefits. They may be subtle, less intuitively obvious, or of longer term. It follows that for secondary benefits it is therefore more difficult to establish cause and effect, but nevertheless they can be powerful justifications for pesticide use.
For example the higher cabbage yield might bring additional revenue that could be put towards children's education or medical care, leading to a healthier, better educated population. There are various secondary benefits identified, ranging from fitter people to conserved biodiversity. Tremendous benefits have been derived from the use of pesticides in forestry, public health and the domestic sphere — and, of course, in agriculture, a sector upon which the Indian economy is largely dependent.
Food grain production, which stood at a mere 50 million tons in —49, had increased almost fourfold to million tons by the end of —97 from an estimated million hectares of permanently cropped land.
This result has been achieved by the use of high-yield varieties of seeds, advanced irrigation technologies and agricultural chemicals Employment Information: Indian Labour Statistics, The use of pesticides has been ongoing for years, the same length of time that opposing groups have debated about whether this practice should continue or should alternatives be used.
Pesticides are chemicals used by farmers to combat agricultural pests in most parts of the world. Despite the advantages of using pesticides, there have also been fears of these chemicals causing death in humans. Here are some of the positive and negative effects of pesticides according to supporters and critics.
Enough Food Supply People in favor of using pesticides on plants and agricultural products say that since farmers have been using these chemicals to destroy pests and other organisms which eat these crops, harvests increased and more produce has become available for agriculturists to market and consumers to put on their tables. Easily Available Supporters of the use of pesticides claim that nowadays, these chemicals can be bought in local stores and supermarkets.
Consumers, both farmers and gardeners will not have a hard time finding for them anytime the need arises. And with more manufacturers competing for sales, these pesticides have also become more affordable.
Safe Advocates for the use of pesticides agree at some point that there might be chemicals in pesticides that can affect health but they argue that in general, these pesticides are safe. There are different pesticides in the market and some manufacturers have also come up with environment-friendly products like herbicides which contain less or no harmful chemicals at all.
These products are just like the products with no toxic substances or with organic ingredients, thus, they are safe. Pests Eradication Perhaps the major benefit of using pesticides is its ability to kill unwanted pests and species that destroy crops and plants. They are also used to destroy species that are harmful to trees in the forests. Loopers and budworms are just two of these forest enemies that kill thousands of trees because they affect foliation.
Experts have studied natural bacteria in the environment that help kill insects, larvae and budworms. One of the bacteria is Bacillus thuringiensis var. Scientists were able to extract the properties of Btk and were able to produce pesticides. Lower Food Costs Supporters of the use of pesticides claim that ever since farmers have been using pesticides, the prices of produce and other food products have lowered.
The costs of goods and commodities in the market are a combination of the expenses from production, raw materials and the like. This is the same with agricultural products. If there is little harvest, farmers will have to raise their prices to at least get back their losses or break even.
With pesticides, losses have been reduced which makes it easier for farmers to offer their products for lower costs. Accidental Ingestion Opponents of the continuance of using pesticides argue that when toxic chemicals, like the ones in pesticides, are ingested by humans, it can be hazardous to their health.
The use of these harmful chemicals is common, especially in third world countries. Some farmers might be too careless to protect themselves in handling these chemicals like not wearing gloves or covering their faces.Crochet block stitch
When they eat with bare hands, it is possible for them to ingest the residue of these chemical and they can also inhale these pesticides which can lead to respiratory problems. Decline of the Number of Pollinators Critics also point out that when pesticides are used, pollinators like bees and butterflies are affected and decline in abundance and occurrence become evident.Linda Crampton is a biology teacher who is interested in environmental issues. She is very concerned about the harmful effects of pollution.
All living things strive to survive, but unfortunately the needs of other creatures sometimes conflict with our needs. An example of this conflict is the struggle between pests and humans. Pests are creatures that injure or kill plants or domestic animals, transmit disease, cause economic damage, or are a nuisance in some other way.
They eat our food crops or ornamental plants, infect plants that are useful to us, make us sick by transmitting infectious organisms, infest our livestock and pets, and destroy property. An effective form of pest control is essential if we're going to win the battle with pest organisms. Many different chemicals are used to kill pests. These pesticides often work well, but since they're designed to kill living things they may cause serious problems in humans or pets.
Pesticides contaminate the environment and the food that we eat and may enter our bodies when we're applying them to our plants or animals. They sometimes harm other organisms in addition to their target. Another problem with using chemicals to control pests is that a pest may become resistant to a pesticide. Biological pest control involves the use of another living organism to kill a pest. There are three types of biological pest control.
In classical biological control, natural predators, parasites, or pathogens of a pest are imported into an area to protect a crop or livestock. A "pathogen" is an organism that causes disease. Importation can be a useful strategy when the pest has been introduced from another region and has no predators in its new habitat. In conservation biological control no new plants or animals are introduced to an area, but the environment is manipulated to favor the survival of local enemies of the pest.
For example, a farmer or gardener may provide additional food sources or suitable habitats for a pest's enemies. In augmentation biological control, plants and animals that control a particular pest and are already present in an area are increased in number by inoculation or inundation.
Inoculation is the introduction of relatively few organisms.If you need to use pesticides, you might be confused as to which one you should choose. I get questions all the time from people who are confused whether one choice is better and safer than the other. So, should you use natural or synthetic pesticides? Some pesticides have less dangerous chemicals if they are considered natural. After all, you want to choose the best pesticide to suit your needs, while still making sure you are using a product that is both safe and effective.
It can be hard to define what is better when you are choosing pesticides. When choosing a pesticide, you have to ask yourself what better looks like for you. For example, you may need to go with natural pesticides if you are planning to cultivate an organic garden. Or if you need immediate relief from pesticides, a fast-acting synthetic formula might be better for you. Mainly, they are extracted and synthesized through different methods.
If a product is natural, it is either extracted directly from the ground, plants, or animals. If a product is synthetic, that means that it is cooked up by artificial means in a laboratory.Change download location firefox android
What you should also know, is that certain chemicals are more dangerous to both animals and humans than others are. Do not sacrifice your health in order to just get a product that is more readily available, or cheaper. Your choice of pesticide may also be depending on whether or not you have children or pets. Both could be harmed if they got into and consumed certain chemicals.Matlab plane model
If you have a child or pets, make sure you research the pesticide you are purchasing is safe for them to be around. Otherwise, you might end up having to make a trip to the emergency room, or the emergency veterinarian.
Biological vs. Chemical Pest Control: Benefits and Disadvantages
When you go to use any pesticides, make sure to use precautions. Keep the number of the local poison control center on hand in case of an emergency.
As we said before, these products are derived from the ground, plants, or even animals. While they have been heavily promoted in recent years, you might be wondering what the pros and cons of natural pesticides are. Generally, pesticides created from natural means are much more friendly to the environment. Natural pesticides work better over the long run because pests are less likely to develop a tolerance to them. This means that over a long period of time, these pesticides will be more effective than ones pests have developed a resistance to.
The use of natural pesticides may be healthier for you, your pets, and your children. This is especially true if you are using pesticides on a food garden, like ones with vegetables and fruits that you intend to consume. This results in better overall plant growth.
It may also mean less chances of contamination. This is a big part of why natural pesticides are considered a solid step in the direction of going green. However, nothing is ever completely perfect, especially when it comes to the use of pesticides. So, here are some of the cons of using natural pesticides. Unfortunately, many people who want to use only natural products may not be able to afford them.
This is part of why synthetic pesticides still remain popular.
Some natural products may be much less effective than synthetic ones. This largely depends on the ingredients used in the pesticide. When you use natural pesticides, it may also take much longer for them to work than with conventional synthetic products. And with the delay, you might see an increase in pests during this time. These natural chemicals may not be as strong as their laboratory-grown counterparts, so this means that you may require more knowledge to properly use them.
This is so you are able to make sure they are effective enough to work.All Rights Reserved. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply.

Impact of pesticides use in agriculture: their benefits and hazards
Asked in Agriculture, Gardening Why is the use of bio pesticides encouraged over chemical pesticides? Asked in Agriculture, Gardening What reason might a farmer have for using biological control instead of chemical pesticides?
They kill agricultural pests.Pesticides are important. They help farmers grow more food on less land by protecting crops from pests, diseases and weeds as well as raising productivity per hectare. Production of major crops has more than tripled sincethanks in large part to pesticides. The amount of wheat has increased nearly percent. Without pesticides, more than half of our crops would be lost to pests and diseases.
All farmers use pesticides, including organic farmers. Whether from synthetic or natural sources, pesticides are used by all farmers. The difference is organic farmers can only use pesticides from natural sources. But both synthetic and natural pesticides have various levels of toxicity.
Food crops must compete with 30, species of weeds, 3, species of worms and 10, species of plant-eating insects. Pesticides can prolong the life of crops and prevent post-harvest losses. Currently, about million people around the world — one in seven of us — are going hungry. To reduce hunger, we need to increase food productivity. Pesticides help farmers do that. Pesticides enable farmers to produce safe, quality foods at affordable prices. They also help farmers provide an abundance of nutritious, all-year-round foods, which are necessary for human health.
Fruits and vegetables, which provide essential nutrients, are more abundant and affordable. Grains, milk and proteins, which are vital to childhood development, are more widely available because of lower costs to produce food and animal feed. Crop quantity and quality rely on crop protection.
