use of pesticides : Pesticides are substances or mixtures of substances that are mainly used in agriculture or in public health protection programs in order to protect plants from pests, weeds or diseases, and humans from vector-borne diseases, such as malaria, dengue fever, and schistosomiasis. Insecticides, fungicides, herbicides, rodenticides.
Food should be protected from 30,000 species of weeds, 3,000 species of worms and 10,000 species of herbivorous insects. Also, the threats do not stop after the crops enter the market. Insects, molds and rodents can all cause damage to food products in storage. Pesticides can extend crop life and prevent post-harvest damage.
Currently, about 925 million people around the world suffer from hunger. To reduce hunger, we must increase the productivity of food products. Pesticides help farmers do this a lot.
Chemical or natural toxins enable farmers to produce safe and quality food at affordable prices.
They also help farmers produce plenty of nutrients throughout the year that are essential for human health.
As a result of using pesticides, fruits and vegetables, which provide essential nutrients to the human body, will be more abundant and more cost-effective.
Cereals, milk, and proteins, which are vital for a child’s growth, will also be widely available because of the lower cost of producing feed and feed.
The quantity and quality of agricultural products depends on crop protection. For example, one study found that without the use of fungicides, the yield of most fruits and vegetables was reduced by 50 to 90 percent. In addition, chemical toxins reduce exposure to food contaminated with harmful microorganisms and natural toxins and prevent food-related diseases.
They are used by farmers to control weeds and harmful insects, and a significant increase in their use in agricultural products has been reported.
About one third of agricultural products are produced depending on the application of pesticides. Without the use of pesticides, fruit production would be reduced by 78%, vegetables by 54% and cereals by 32%.
Therefore, they play an important role in reducing diseases and increasing crop yields worldwide.
When pesticides are applied or disposed of on the plant, they have the potential to enter the environment. Upon entering the environment, these toxins can be subjected to processes such as transport (or movement) and degradation. Their destruction in the environment causes the production of new chemicals.
Pesticides are transferred from the intended location to other non-target environments or plants through transfer processes such as adsorption, washing, evaporation and runoff.
Different types of chemicals indicate differences in pesticides in environmental behavior. For example, organic chlorine compounds such as DDT have low toxicity, but show significant ability to accumulate in tissues and persist in causing long-term damage. The sale of these toxins is currently banned in most countries. Organophosphate pesticides, on the other hand, have a low shelf life and significant toxicity to mammals.
Three billion kilograms of pesticides are used annually worldwide. However, only 1% of them are used effectively to control pests in target plants.
Thus large amounts of them penetrate into non-target plants and surrounding environments.
As a result, pesticides pollute the environment and have a negative impact on human health. These compounds are often named according to the type of pest they control. There are different types of pesticides and they have different categories accordingly.
Chemical pesticides are divided into organophosphate, carbamate pesticides, organochlorine insecticides and pyrethroid pesticides.
Bio-pesticides are special types of tertiary products derived from natural materials such as animals, plants, bacteria and certain minerals. For example, canola oil and baking soda have pesticide applications and are considered biological products.
