Pesticides are substances used to control unwanted microorganisms, fungi, insects, etc. Harmful include living things, plants, or other organisms that damage health or the economy.
At the moment, public attitudes towards pesticides are very mixed. They are certainly useful, especially in terms of crop conservation. However, at the same time, they pollute the soil and even groundwater, can become a threat to human and animal health.
Therefore, at the moment, the use of substances such as pesticides and agrochemicals is regulated by the legislation of all developed countries.
To date, in stores you can find a huge number of drugs that relate specifically to the two above categories. Selling and buying them is not prohibited. However, only species listed in the State Catalog. If you need to know exactly which drugs belong to this category, you can see a special pesticide guide.
Such tools can be used not only in agriculture, but also, for example, in everyday life. After all, various kinds of insects are often undesirable in certain places. A pleasant pastime in nature can be prevented, for example, by mosquitoes.
And there is no need to talk about such unpleasant "neighbors" as bugs and cockroaches. Against such insects, special agents are also used. In this case, pesticides are insecticides, one of their varieties. Often repellents belong to 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 what weed control products are called . They can have both 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 nightshade nightshade. Fungicides containing sulfur or mercury are also available. Sulfur is used to combat such infections as, for example, powdery mildew.
Synthetic organic fungicides include dithiocarbamates. To prevent mold from appearing in bread, sodium propionate (a pesticide of this class) is used.
Pesticides are, as already mentioned, either organic or inorganic substances. Inorganic types are not very effective; they can accumulate in the soil. Organic products are divided into natural and synthetic. The first type is represented, for example, by a substance such as nicotine alkaloid. Pesticides of this kind are currently not used or are rarely used. More commonly used are synthetic organic pesticides. Such, for example, as carbamates, organophosphorus, organosulfur and pyrethroids. Prohibited organochlorine pesticides, including DDT, as they poison the environment.
So, pesticides are both beneficial and harmful substances. To apply them, of course, is possible and necessary. However, within reasonable limits and only allowed.
