If their resistance to the chemical substance has a genetic basis, they will in turn pass these genes on to their progeny to make the population more resistant. Many different chemicals are used to kill pests. These pesticides usually 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 organisms other than their target. Another problem with using chemicals to control an organism's population is that a pest can become resistant to a pesticide. In addition, it is far beyond the scope of this curriculum to address the many details of the hundreds of compounds that fall into the agrochemical category. Concerns about chemical residues in food products have led to a completely new marketing approach in which agricultural products are advertised as “residue-free”.
If public pressure against the use of these materials continues, this trend may change, but for now society remains divided over the use of agrochemicals in food production. It is a substance or mixture of substances that are chemically, biologically, or physically manufactured to repel or destroy the pest. However, there are many downsides to using chemicals in the garden that should make us rethink whether spraying our problems is really justified. Even so-called experts in the fields of agriculture, human nutrition and medicine do not always draw the same conclusions about the use of agrochemicals in food production.
After the detailed guide to biological pest control from the previous chapter, now is the time to introduce you to everything you need to know about chemical pest control methods used for pest extermination anywhere in the world. Powdered chemical pesticides are very unsuitable for outdoor application, since they are very easily propagated by wind and penetrate the human body through the respiratory system. For many in the public sphere, the use of synthetic or manufactured chemicals in crops presents a frightening picture of immediate and long-term health problems. According to a study, the primary use of a chemical in the agricultural field leads to a chemical in food production, the intake of low levels of pesticides is found in food consumed by people.
These are some of the advantages of using pesticides in agricultural production and in homes or offices. In the most recent list, strawberries have the highest amount of pesticides, spinach has the second highest level of chemicals, and kale, collard greens and mustard leaves rank third. The foods that are produced will be pesticide-free (or low in pesticides, since the food may have absorbed chemicals distributed by other people). It is recognized that biological control is most effective against pests that are tolerable enough that they only need to be suppressed, not completely destroyed; this method is more friendly to the environment and, in general, more cost-effective than chemical pesticides.
