When the question of assignment Environmental pollution in neighborhood was given, what first came into our mind is the Endosulfan incident and how it devastated normal life in various places of Kasargod. We visualized such a disaster in our locality and what it would have been had we been there in the locality ruined by Endosulfan disaster, thus we could estimate the relevance and how important is it to prevent the recurrence of such an incident again.

So aiming at the prevention of such a disaster again, it becomes necessary to minimize the use of highly toxic pesticides in the area which are more inclined to the human habitat. Even we must try to reduce the use of any kind of chemical substances in our daily life.                           For a sustainable life we must explore more natural methods to counter the evolving problems and confront the situation boldly in the belief that the outcome is definitely not going to hamper the nature. Since it’s a fact that, for every problem rose in nature, there is solution hidden in nature itself. So now it becomes our duty to search for that solutions and implement them for a better tomorrow.

Our study relates to the use of pesticides in the different cultivations & vegetations and its deleterious effects on the environment & our daily life, how it can be solved in an environment friendly way. so here is the “DISASTROUS IMPACT OF PESTICIDES IN OUR DAILY LIFE


Nowadays people have realized the importance of self sufficiency and the impact of escalating prices of vegetables in market on the life of common man. It has now become their necessity to grow vegetables in their own household and to remain self sufficient, unaffected by the fluctuating prices of vegetables in market.

When they started the vegetable cultivation on their own their primary aim was to get good yield in a short period of time, thus they started buying toxic pesticides from the market. Its true that the use pesticides will give the desired result for them but they are unaware of the negative implications that it can cause on the environment as well as on his life in future. So it is important for the people involved in such kind of agriculture to be aware of the deleterious effects of the pesticides.

We have realised that chemical toxic substances are very poisonous and have adverse effects on human health, so we must try to maximize the utilization of environmental friendly pesticides. Here are some which we can use in our house hold

  1. 1.      Garlic Spray : it is an environment-friendly natural pesticide which repels many pests such as aphids, spider mites, and white flies. Not only is this environmentally safe but it is also biodegradable and does not affect flavor. Don’t worry about the garlicky smell when you first spray it. Once it dries, you won’t be able to smell it; however, the pests will and they will stay away from your plants.

2. Hot Pepper Wax: another  environment-friendly natural pesticide, is a blend of food-grade paraffin wax, herbs, and capsaicin, the active ingredient in hot peppers. Hot pepper wax is derived from cayenne peppers.This environment-friendly natural pesticide serves two purposes: 1) Keeps many garden pests such as aphids and white flies and other pests which don’t like spicy things away from your plants and 2) protects plants from dry or windy weather.

Since the plants do not absorb this natural pesticide, the flavor of your vegetables are not affected. Before preparing, wash the vegetables under warm running water to clean away any remaining wax.

Caution: When you do your spraying, be careful not to get any of the spray on your skin or in your eyes (wear plastic gloves) because the capsaicin can cause an irritation.

3. Insecticidal Soap,:a well known botanical mixture, is another environment-friendly natural pesticide which is most effective on soft-bodied insects such as aphids. To work best, it must remain in contact with the pest for as long as possible, so you may want to use this natural pesticide spray early in the morning or late afternoon/evening when it takes longer to dry.

This environment-friendly natural pesticide a) does not harm most beneficial insects, b) has a low impact on mammals, birds, aquatic organisms, and other wildlife, and c) is damaging to predatory mites and some insects such as hoverflies in their larval stage.Its main ingredient, potassium salts of fatty acids derived from plants, is what makes this natural pesticide mixture environment-friendly and biodegradable. It works well because the soap spray damages the insects’ cell membranes and causes the vital cellular fluids to leak and the insect to die.

Note: If mixed in water containing high amounts of minerals such as iron or calcium, it may be less effective.

4. Neem leaves : derived from the seeds of the neem tree, has an active ingredient called azadirachtin which blocks the progression of the insect’s life cycle. Although it might take a few days for the effects of the neem to be seen, you will notice that as soon as Neem is applied to the plant, the insects seem to lose their appetite.

As a spray, neem is also an extremely environment-friendly natural pesticide. It has no effect on beneficials such as butterflies, spider, bees, earthworms, and ladybugs. Moreover, it has little impact on birds, aquatic organisms, fish and mammals, or other wildlife.

You may also use the neem oil insecticidal soap which combines the two products.

5. TOADS: Toads like to work at night and seem to particularly like slugs and cutworms. However, their meal will include gypsy moth larvae, sowbugs, armyworms, and various beetles, up to 15,000 garden pests a year. In order for you to have toads remain in the garden, you must provide a cool, dark spot where they can hide in the daytime, a spot from which they can make a quick get-away. Take a 5-inch or 10-inch plastic flower pot, cut a big hole on the side and tuck it under a shrub out of sight.  Although toads seem to like these “homes,” they would often  just make themselves at home under full leaved shrubs without the flower pot . . . wherever the “food” could be found

6. TOBACCO LEAVES:  The tobacco leaves mixed in water and kept overnight is an effective pesticide which can destroy weeds. It has the presence of nicotin which could penetrate into the body of pests and can destroy the nervous system and its body cells.soft skinned pests are most vulnerable to nicotin.

7. ROTENONE :   Rotenone is an odorless chemical that is used as a broad spectrum insecticide , piscicide, and pesticide. It occurs naturally in the roots and stems of several plants such as      the jicama vine plant. Its solution  kills potato beetles, cucumber beetles, flea beetles, cabbage worms, raspberry bugs, and asparagus bugs, as well as most other arthropods. Rotenone rapidly bio-degrades under warm conditions so there is minimal harmful residue. A light dusting on the leaves of plants will control insects for several days. It is known to be un harmful to humans when used properly.

8. PYRETHRINS: The pyrethrins are a pair of natural organic compounds that have potent insecticidal activity.The pyrethrins are contained in the seed cases of the perennial plant pyrethrum(Chrysanthemum cinerariaefolium), which is grown commercially to supply the insecticide. Pyrethrins are neurotoxins that attack the nervous systems of all insects. When present in amounts not fatal to insects, they still appear to have an insect repellent effect. Pyrethrins are capable of replacing organophosphates and organochlorides as the pesticide of first choice.

9. ACORAS CALAMUS(“VAYAMB” in Malayalam):  it is a medicinal root plant which is highly useful as an insecticide for lice, bedbugs, worms etc. its solution which applied by spraying can effectively drive away the weeds and provide immunity for the plants.

There are lots of such nature friendly methods that have left unexplored so it is important for us to find those and make optimum use of such pesticides rather than the toxic ones.

Handling of pesticides is very important, so here are some basic facts that need to be ensured while handling pesticides.

  1. Name of pesticide
  2. The poison content in it, same pesticide may reach the market with different  chemical contents so you must check the chemical contents and the percentage of poison content in it.
  3. The state in which pesticide is supplied whether rits in powder state, liquid or granules
  4. The symbols and colors highlighting its harmful effects.
  5. Detailed  anti poison medicines which needs to be taken during inadvertent consumption of pesticide.
  6. The volatility and explosive character of the pesticides must be ensured
  7. Its usage in amounts against different pests and care must be taken in spraying it uniformly as excess dose can result in making the fruit/vegetable highly poisonous so if it exceeds the lethal dose then it will have disastrous effects on people consuming it.
  8. The pesticides which became old must be disposed off in an effective manner. It must be mixed with water and thrown into barren land or else must be buried in earth far from pond,well,and other water resources because the percolation of these substances into the water resources can make the water we rely upon for our daily usage poisonous.
  9. While spraying the pesticides ,people must isolate their body parts by wearing protective cloths covering their entire body and use mask to cover the face as well as gloves on hand.
  10. After spraying pesticides you must clean your hands and face with soap solution, bath is preferable.


The study of “ DISASTROUS IMPACT OF PESTICIDES IN OUR DAILY LIFE” have given as an insight into the various hidden danger associated with the use of pesticides and how we can combat it with the preventive measures & environmental friendly methods. So the time has come for us to realize the real potential hidden in nature and unleash it for the sustainability of human life free from dangerous diseases and epidemics. Hope the humans will show patience to discover natural methods to counter pests rather than going for hasty nasty toxic substances.
