September 2007AbstractIn this work optical methods are evaluated in regard to analysis of pesticides in environmentalcompartments and on biological surfaces such as leaves. Laser induced fluorescence (LIF) spec troscopy is suitable for fast in situ measurements and can be used for non invasive and onlinescreening of pesticide distributions. For investigations of pesticide colloidal suspensions in water,laser induced plasma breakdown detection (LIBD) is utilized. LIBD has the potential to detectnano sized particulates at low concentrations.Pesticides are an integral part of modern agriculture and are used to increase production and im prove products. Today, there is a huge variety of different pesticides used as herbicides, fungicides,insecticides, growth regulators, etc.
