Where large-scale insect control measures are needed chemical pesticides are mainly used. Insect population is not just exterminated by them at one stroke, but also reduce their recurrence. But their adverse effect on ecology and the surroundings isn’t fathomed yet. Lots of study results came out lambasting the usage of these killer substances. The best disadvantage is the fact that if these toxins doesn’t discriminate between benign and dangerous animals which come within their way. The consumer can be even harmed by normal exposure too. Deposit from these toxic chemicals ultimately enters fruits which they’re utilized, leading to individuals consuming dangerous levels of killer with harmful effects and the plant. Instances of nervous and physical problems discovered to be due to over use of pesticides currently nearly corresponding to that due to insects itself.

Another paradox about chemical pesticides is the fact that although they exterminate insects, they assist the pests creating improved resistance to these toxins, necessitating the usage of more amounts in subsequent years. This more perverts the previously injured habitat. It’s been believed that over 95 percent of used pesticides achieve goals apart from what was intended. Air friendly species, water and dirt have already been perverted because of the intensive use of these to some great extent.
