The biochemical principles of the mode of action of plant protection products (PPP) are presented. Important topics are mechanisms for selectivity, development of resistance, residue formation in crops and food safety as well as behavior in the environment.
The structures and modes of action of modern pesticides (synthetical compounds, natural compounds) are presented. The structure-activity relationships lead to considerations of actual use conditions in crops such as fungicides in viticulture, residues in edible parts of treated plants, possible side effects and environmental fate.
After a short introduction on pesticide registration (administrative process as in Switzerland and EC, food safety), the biochemical background of the mode of action of important groups of PPP active ingredients is presented. Furthermore, selectivity of pesticides, leaching of herbicides to groundwater, accumulation of pesticides in soil, development of resistance of fungicides, formation of residues in edible parts of the crops, and side-effects on non-target organisms shall be covered.
An e-script (pdf-files, in German) is is provided as download at the beginning of spring term.
