Over the last three decades the Pesticide Application Group has provided a forum for researchers from around the world to discuss progress with the development of pesticide application technology. During this time great advances have been made to improve the efficacy and safety of pesticides, resulting in lower doses of pesticides in the field, leading to lower residue levels in produce and the environment. Scientific and engineering advances can be exploited more readily with the regular contact between the many research groups working with crop protection and production techniques.
