pesticides: useful and harmful effects

Updated on July 28, 2009

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.

Alternatives available for chemical pesticides

There are surely alternatives available for pesticides such as  pheromones and microbial pesticides, insect breeding and Genetic Engineering. These methods are safer than traditional chemical pesticides.

But these methods are not cheaper as compared to chemical pesticides. Now choice is yours, either you wants to bless your child with 'atleast limbs' or put yourself and your children in a never ending pain.

      I have to disagree. Yes pesticides can be harmful, but they are not the cause of all health disorders.

      Yes, insecticide and pesticide is really so bad, I am using lots of insecticide for my apartment due to infestation of fire ants. It's all over the place even in electrical outlet ants will come out, and walls and ceilings and tiles. They go everywhere even flat iron will be clog by insect, they'll crawl into my bed too and my cabinets of clothes. I have been using insecticide for a month now and I experience dizziness, nervous problem, anemia, headache, my arms and legs feel numb and tingling sensation. I have lots of bruises too so I know it is because of the insecticide I have been spraying that I will also inhale. I just don't know what to do with the fire ants I tried all google suggestion nothing works even the corn meal, and citrus and so many herbs. I can't move out this is a cheap apartment I can afford.

      In n agricultural fields pesticides are helpful and also harm ful....

      In one way if pesticides are applied on the fields.. the insects will be dead....

      but in another way it is harmful for human kind...

      Иногда, создается впечатление, что фирмы, которые занимаются производством аксессуаров для iгаджетов уже сумели перешагнуть все возможные пределы. Гитары, невероятные чехлы, всевозможные доки и даже оригинальные наклейки, которые создают имитацию геймпада – все это плод фантазий разработчиков аксессуаров. Но вот американского изобретателя Шейна Уайтона, абсолютно не интересуют никакие имитации, его внимание можно привлечь исключительно технологически-сложными и передовыми изобретениями. Ведь сам он занимается именно таким «ремеслом». Последние его изобретение было устройство, призвание которого управлять айфоном при играх, в которых нужно активно использовать акселерометр и гироскоп.

      Теплопроводность – способность шиньона пропускать тепловой поток при условии разных дам поверхности. Степень теплопроводности шиньонов характеризует юмор, который равен количеству тепла, проходящего через тонзуру из испытуемого шиньона толщиной 1 м площадью 1 м2 за 1 ч при разности дам противоположных поверхностей тонзуры 1 К. Коэффициент теплопроводности измеряют в Вт/(м?К) – СТБ 4.206-94

      Pesticides were developed to help humankind, as usual we humans love to play god and constantly alter and meddle with nature and balance of life. Today the dependence on harmful chemicals is more than ever and the price we pay is devastation of human societies and lives due to cancer, deformities and other such deceases. Organic farming is the future and a way to a healthy life. Pesticides and chemicals are the Hiroshima of current day

      This is so sad... people really have to watch out what they are exposing their kids to or the kids. See things like these are so devastating to the families and the children who have these problems. Someone needs to do something about it. This is a free country. Not a hurting country where you can do anything and hurt people. If they have a right to put stuff on the food we eat or on their crops, we certainly have a right to complain and fight against! This is not right! Stand up for what is right and stand down for the wrong in this world everyone! - 13 year old FM

      Wow impressive stuff! Maybe an idea for a future hub page would be organic methods of pest control for those of us with a green thumb! I don't really have a green thumb myself but picked stuff up from my adopted mum. She would grow garlic in her garden and rotate it with other crops to keep the pests away in the first place. I also heard somewhere that you can put a few ciggys out in water and have the water near your garden beds, it will attract pests into the water and is poison so will kill em. I don't know if using the dirtied water to spray on the plants would be considered safe as tobacco is a plant itself?

      the child is without limbs from the time he is born and its all due to the poisoning effect of large quantity of pesticides destroying the promoter gene which will ultimately result in production of limbs.

      Yes all pesticides are not harmful.

      You wrote a good article, but I would not say that all pesticides are the main reason for all health problems, and when I look at that child, I do not see, something deformed, I see a beautiful child. But I guess its all in how you look.
