Controlling chemicals can bring a number of benefits to society and industry by making production and supply chains cleaner and safer, and reducing the risk of accidents. It also provides incentives to develop safer chemicals and safer and more resource-efficient production methods. Excessive use of chemicals for pest control promotes the evolution of pest 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 transmit 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, there were more than 2,700 known cases of resistance of 540 pest species to more than 300 pesticides in 2000, including the diamond-backed moth and the green peach aphid, both agricultural pests. One of the main advantages of chemical pest control is its efficiency.
Most chemicals act very quickly and, when properly selected, are very effective in eliminating pests. Chemicals can be used to control or kill specific pests on a farm. Biological pest control has some distinct advantages compared to chemical processing. Farmers and gardeners don't have to worry about poisoning themselves, their families, or their pets when they treat their crops or plants.
There are no toxic chemicals to store and there are no worries that children or animals will discover stored pesticides. There are no pesticides that give off dangerous fumes, accumulate in soil, or accumulate in water. The foods that are produced will be pesticide-free (or low in pesticides, since the food may have absorbed chemicals distributed by other people). Biological control uses a living organism to kill pests, while chemical control uses different strong chemicals to kill, prevent, or repel pests.
Therefore, biological control is an ecological method, since it does not harm the environment or people, while chemical control is not ecological. Another disadvantage of chemical pesticides is resistance. Pesticides are usually effective only for a (short) period of time on 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. The effects of a pesticide on the human body depend on several factors, including the nature of the pesticide, the amount of chemical involved, the duration and frequency of exposure, and the age of the person being exposed to the chemical. 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.
This makes it easy for farmers to control virtually any pest that uses chemicals, since they can easily buy them at their local points of sale. PIPs are chemicals produced by plants that have been genetically altered to produce a particular pesticide. When resistance is not an issue, pesticides are generally very effective in controlling pests when considering the other disadvantages. Rodenticides are chemical pesticides, designed specifically for the extermination of rodents such as rats and mice.
Chemical pesticides are highly effective against pests that feed directly on crops over a very large area, but they must be used safely and the economic problems of modern pesticide use must be largely taken into account. However, the real revolution in chemical pesticides occurred during the 18th and 19th centuries, when the industrial revolution required far more efficient pest treatments in terms of scale, effectiveness and speed. Biological pest control often takes longer to work than the chemical method and often reduces the pest population to a low level rather than completely eliminating it. I need the reason biological control is better than chemical control in pest and parasite control.
Unlike some chemical pesticides, pyrethrins break down rapidly in the environment and are said to be non-residual chemicals. Unlike some cases of chemical pesticide programs, biocontrol reduces, but does not eradicate, pest populations. Symptoms of acute pesticide poisoning appear immediately or soon after exposure to a hazardous dose of the chemical. Chemical pesticides based on emulsifiable concentrates have no residual effect on fruits and vegetables.
