The use of pesticides
Pesticides prevent, destroy or control pets. Pests are organism that causes damage to plants animals or food, such as bacteria, viruses, rodents, worms, fungi, insets, or weeds.
The term pesticide is very broad and includes herbicides (to control weeds), insecticides (to control insects), fungicides (to control mold), mildew, and fungi). rodenticides (to control rodents), and disinfectants (to control bacteria and viruses).
Three quarters of the pesticide use is for agriculture (mainly on crops in the fields), but it is also used post harvest during transportation and storage to prevent mold growth or insect infestation.
While we may not think of household cleaners, pet flea collars, lawn and garden products, and insect repellants as pesticides, they are.
Since the beginning of agriculture humankind has used in an attempt to control nature to ensure good crop yield.
Egyptian records from 1500 BC contain instruction for preparing insecticides to control lice, fleas and wasps.
The Greeks were using sulfur by 1000 BC to control insects, as did European farmers in the eighteenth century.
The Chinese controlled insects with a mixture of arsenic and water,
In 1865 farmers discovered Paris green, a mixture of copper and arsenic, as a way to control the Colorado potato beetle.
A similar substance called Bordeaux mixture saved the grape industry in France from a fungal disease in the 1880s.
The first synthetic insecticides and herbicides were produced in the early 1900s.
