Introduction to pesticides
A pesticide is a substance or combination of different substance whose sole purpose is to prevent, destroy or control the pests.The term pesticide, in broad terms, can also include herbicides (inhibits the growth and reproduction of some harmful plants), insecticides( prevent growth of insects) and fungicides (inhibits the growth of mildews, yeasts, and molds).
A pesticide can be chemical substance( DDT) or biological( Ampelomyces quisqualis)or antimicrobial( sterilizers , disinfectant) or any device used to kill pest. Pests includes any weeds, nematodes(roundworms), insects, fish or any mammals that can destroy crop.
why pesticides are useful
The pesticides are mainly considered by farmers due to their economic values: cheap and good results. The pesticides can protect a crop even if there occurs a 'sudden outburst of pests' and hence ensures increased production. If crops are protected means production of more attractive fruits and vegetables - what else a farmer need. Pesticides delays the rotting of produced food which means they allow longer shipping times and increases the shelf life of fresh produce.
Harmful effects of pesticides
Note:Chemical pesticides are the main reason for all the health problems in humans.
Now proceed to all important point whether we should consider money or ourselves first. Prolonged exposure to pesticides in humans can lead to severe disorders in our reproductive, nervous and immune system PLUS in some cases can even lead to cancer. Exposure to some pesticides can be 'hell' for a pregnant lady as it can easily lead to death of baby and even if the baby is produced will have lots of disorders or even loss of limbs.
However, pesticides are not like poisons where a very small amount can be deadly but we need to always, if possible, protect ourselves from exposure to pesticides. Farmers can use mouth masks or other accessories to keep them away from intake of pesticides.
