Detailed explanation-1: -Toxic effects by pesticide exposure can range from mild symptoms, like minor skin irritation or other allergic symptoms, to more severe symptoms, like strong headache, dizziness, or nausea. Some pesticides, e.g., the organophosphates, can cause severe symptoms, like convulsions, coma, and possibly even death.

Detailed explanation-2: -Many insecticides act upon the insect’s nervous system (e.g., cholinesterase inhibition), while others act as growth regulators or endotoxins. Most act on neurons by causing a sodium/potassium imbalance preventing normal transmission of nerve impulses.

Detailed explanation-3: -Pesticide resistance will pop up sooner or later Pests vulnerable to the pesticide die quickly, and therefore more resistant individuals stay alive. Also, naturally occurring genetic modification may produce individuals with resistance to the pesticide.

Detailed explanation-4: -With each pesticide application, those individuals at the more resistant end of the spectrum survive and reproduce. Over the years, the proportion of the population that can survive a pesticide spray increases, until that pesticide eventually becomes ineffective.
