A significant portion of fertilizer and pesticide applied to the soil runs off into surface water or leaches into ground water.
Spraying of pesticides had lead to ecological damage like human toxic effects, cancer and organ damage from breathing and ingesting pesticides.
Increase in cropped area and irrigation have problems like soil erosion, water logging and steady buildup of salts.
The biggest problem with pesticides is the development of genetic resistance by pest organisms and they will become immune to the fungicides.
Sometimes insecticides kill natural predators and parasites which may increase new pests’ growth.
Pesticides may accumulate in the bodies of animals which is called bio-accumulation. This problem affects animals and when that affected animal is eaten by a carnivore leading to the disease or death
