摘要:
AbstractThe use of pesticides demands the assessment of the behaviour of its residues on the treated plants and in the environment. The fate of residues is based on the biochemical degradation in plants, mikrobiological degradation in soils and the photolyzis in atmosphere, on soils and in water. Besides these factors the physical‐chemical processes play a role, such as the evaporation, the wash‐off from the plants and the leaching in deeper lagers of soil and in the groundwater.Many models of the behaviour of residues was developed in the last years which are usual for prognoses. This is especially related to the leaching behaviour in the soil, phytotoxicity of herbicide residues, the fate of residues on plants and the uptake of residues from the soil by pla

摘要:
AbstractPesticide chemistry has still a special importance for protection of human food; new pesticides to develop is necessary because of economical and ecological reasons. A description is given of the synthesis of numerous new heterocycles containing triazino‐, triazolino‐ and thiazolo‐condensed quinazolines, benzodiazepines and benzodiazocines. On principle, all of them are in possession of pesticide‐relevant structure elements like cyclic ureas and thioureas and allow correlations between ring‐size and bioactivity. The starting materials are o‐amino‐phenylalkylamines especially aromatic‐aliphatic 1,3‐, 1, 4‐and 1, 5‐diamines; their prep
