The impact of pesticides consists of the effects of pesticides on non-target species. Pesticides are chemical preparations used to kill fungal or animal pests. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields.
Really a herbicide is a kind of pesticide. Cide means to kill, so a pesticide is just anything that's meant to kill a pest. So all of these are pesticides. So insecticides are meant to kill insects, fungicides are meant to kill fungi, herbicides are meant to kill plants.
