Pesticides are substances used to control unwanted microorganisms, fungus, insects, etc. Harmful refers to living beings, plants or other organisms that are harmful to he alth or the economy.

At the moment, the attitude of society towards pesticides is very ambiguous. They are certainly useful, especially in terms of preserving crops. However, at the same time, they pollute the soil and even groundwater, and can become a threat to human and animal he alth.

Therefore, at the moment, the use of substances such as pesticides and agrochemicals is regulated by the legislation of all developed countries.

Today, in stores you can find a huge number of drugs that belong to the two above-mentioned categories. Selling and buying them is not prohibited. However, only species included in the State Catalog. If you need to know which drugs belong to this category, you can look at a special guide to pesticides.

Such funds can be used not only in agriculture, but also, for example, in everyday life. After all, various kinds of insects oftenundesirable in certain places. For example, mosquitoes can interfere with a pleasant pastime in nature.

And there is no need to talk about such unpleasant "neighbors" as bedbugs and cockroaches. Special means are also used against such insects. In this case, pesticides are insecticides, one of their varieties. Repellents are often included in this category.

Depending on the scope of application, pesticides are also divided into herbicides, fungicides, bactericides, etc. In agriculture, the first two drugs are used. Pesticides are substances that can be of both organic and inorganic origin. Herbicides are no exception. This is the name of the means intended for weed control. They can have both a directed action based on species characteristics, and completely destroy plants.

Fungicides are pesticides used to eliminate and prevent diseases. For example, preparations containing copper are used to combat late blight of nightshade. Fungicides containing sulfur or mercury are also available. Sulfur is used to fight diseases such as powdery mildew.

Dithiocarbamates are synthetic fungicides of organic origin. Sodium propionate (a pesticide of this class) is used to prevent mold in bread.

Pesticides are, as already mentioned, either organic or inorganic substances. Inorganic types are not very efficient,they can accumulate in the soil. Organic preparations are divided into natural and synthetic. The first type is represented, for example, by such a substance as the alkaloid nicotine. Pesticides of this type are currently not used or rarely used. Synthetic organic pesticides are more commonly used. Such as, for example, carbamates, organophosphorus, organosulfur and pyrethroids. Organochlorine pesticides, including DDT, are banned because they poison the environment.

So, pesticides are both useful and harmful substances. Of course, they can and should be used. However, within reasonable limits and only permitted.
