DisadvantagesNon-specific chemicals can kill beneficial insects, the elimination of insect predators to the pest can provoke the resurgence of the pest, pests can become resistant, long-term exposure - HARM to humans. Excessive use of chemical pest control promotes the evolution of pesticide resistance. When pesticides are applied, people who are more resistant are more likely to survive. If their resistance to the chemical has a genetic basis, they will in turn pass these genes to their progeny so that the population becomes more resistant over time.
In other words, chemical pest control acts as a type of artificial selection for pesticide resistance. According to Essential Environment, in 2000 there were more than 2,700 known cases of resistance of 540 pest species to more than 300 pesticides, including the diamond-backed moth and the green peach aphid, which are agricultural pests. Another disadvantage of chemical pest control is non-target effects and toxicity. Many chemicals kill even beneficial insects such as bees and natural predators.
If misused or mishandled, chemicals can poison and even kill humans. On the other hand, the disadvantages of widespread use of pesticides are significant. They include pollution and death of domestic animals, loss of natural pest antagonists, resistance to pesticides, decrease in honey bees and pollination, losses to adjacent crops, losses of fisheries and birds, and pollution of groundwater. Soil fertility is affected by death or damage to microorganisms caused by pesticides.
In addition, some pesticides induce immunotoxicity in humans, which can lead to immunosuppression, hypersensitivity (allergies), autoimmune diseases and inflammation; children may be especially susceptible to the adverse effects of exposure to pesticides. People who regularly work with pesticides, such as farmers, have a higher risk of cancer. Thousands of non-lethal poisonings and cases of cancer each year are attributable to pesticides. Another disadvantage of chemical pesticides is resistance.
Pesticides are usually effective only for a (short) period in a particular organism. Organisms can become immune to a substance, so they no longer have an effect. These organisms mutate and become resistant. This means that other pesticides must be used to control them.
Many different chemicals are used to kill pests. These pesticides often work well, but because they are designed to kill living things, they can cause serious problems in humans or pets. Pesticides pollute the environment and the food we eat and can enter our bodies when we apply them to our plants or animals. Sometimes they harm other organisms besides their target.
Another problem with using chemicals to control an organism's population is that a pest can become resistant to a pesticide. Substance when applied, but are chemically stable so that they have a long shelf life. However, there are a large number of disadvantages to the use of chemical pest control. Pesticides can be very dangerous and poisonous substances, which must be handled with great care.
Obviously, this will reduce exposure to the legal, environmental and public safety hazards of pesticides. However, this drawback is becoming less important, because pesticides that do not break down quickly enough are no longer allowed. Animals or humans at the end of a food chain are more likely to be harmed or killed by the accumulation of pesticides in their system. This is because a farmer only needs to identify the pest and then look for a chemical that kills that particular pest without harming the beneficial insects.
So, if the biological method does not work, a higher dose of chemical pesticides is required, because the pest is already widely spread. Rodenticides are generally considered a threat if consumed by other animals, but that is a serious concern only if large amounts of the chemical pesticide are consumed. Because of these potential health risks, the cost of developing new pesticides has increased dramatically in recent years. For this reason, you should take a look at the two different points of view: chemical pest control with its advantages and why it is not a good practice for pest extermination.
The Environmental Working Group (EWG) publishes an annual list of the Dirty Dozen of the products with the most pesticide residues. It is certainly time for individuals and communities to think very carefully about what forms of pest control should be used. Systemic pesticides are absorbed by plants or animals and must spread inside their bodies to untreated areas before they can kill pests. In standard emulsifiable pesticides, the emulsifier is normally dissolved in an organic solvent and the chemical concentration is irrigated with higher amounts of water.
Pesticides have the disadvantage of their potentially hazardous and harmful chemical properties, which spread easily, however, are relatively cheap and effective. Animals at the top of the food chain, usually predators or humans, have a higher chance of toxicity due to the accumulation of pesticides in their system. Some local governments have even stopped using pesticides on ornamental plants and lawns for purely cosmetic reasons. .
