At the start of the new millennium, crop protection is confronted with the public debate about genetically modified crops and demands for organic food. Pesticides are disliked due to the perception that residues are harmful, despite the knowledge that with their increased use over the last five decades, food quality has been vastly improved and life expectancy increased. Pesticides are also disliked due to the popular belief that toxic chemicals are overused and drift across the environment, adversely affecting water supplies and natural habitats.
