Advantages of chemical pest control Some pest control chemicals kill slowly due to active ingredient. However, most pesticides are designed to exterminate pests in less than 3-4 days, which is much faster compared to organic methods of pest control, such as import or increase. 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. An important advantage of chemical pest control is its efficiency.
Most chemicals act very quickly and, when properly selected, are highly effective in eliminating pests. Chemicals can be used to control or kill specific pests on a farm. 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. 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.
Chemical tactics to control pests can include many types of compounds. Some simply repel or confuse pests. Some interfere in some way with weed photosynthesis, insect molting processes or development. Others, including some botanical insecticides and most conventional insecticides, are widely toxic to living systems.
The term pesticide literally means pest killer. The specific type of dead organism is revealed in the name; that is,. Insecticides kill insects, herbicides kill plants, fungicides kill fungi, rodenticides kill rodents, etc. 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. In this situation, ever higher concentrations of the chemical are needed to kill the pest until the pesticide becomes useless. Individual pests that are resistant to the chemical develop resistance to that particular chemical and can no longer be used to control them. Pesticides are used in IPM programs when effective alternatives are not available or alternatives are not sufficient to prevent pest populations from reaching harmful levels.
Pesticide treatments are often cost-effective, especially if alternatives require large increases in human labor. Each pesticide contains a small percentage of the chemical component responsible for the lethal activity. If the resistance developed is based on genetics, the future generation will not be controlled by that chemical. With increased biological control, plants and animals that control a particular pest and that are already present in an area increase in number by inoculation or flooding.
The agencies also claim that most people are exposed to small amounts of pesticides in their daily lives. Although it may not be a common household product in some countries, neem seeds and seed oil are used to create a natural pesticide that kills many insects. So, would you choose a soap or an organophosphate to control aphids on your houseplants? Lists of common household chemicals and their chemical categories are included in the reference materials. Previous studies have already indicated that periphytic biofilm can control the chemical fluxes of calcium, alkalinity and P from sediment to overlying water (Woodruff et al.
The idea that organisms can be pests is an anthropocentric construction in which the pest is an organism that detracts from the production of resources that humans desire. Before being released for sale, pesticides are required to be tested to determine the amount of the active ingredient that will kill a mammal. When using pesticides, different chemical categories should be applied over time, rather than always using the same one over and over again. .
