The disappearance of azoxystrobin, pyrimethanil, cyprodinil, and fludioxonil on tomatoes in greenhouse was studied. At the preharvest interval, except for cyprodinil, the pesticide residues were below the MRL fixed in Italy. The mechanism of disappearance studied with model systems shows that the decrease in residues was due to codistillation and photodegradation in pyrimethanil, to photodegradation in fludioxonil, and to evaporation and codistillation in cyprodinil. Azoxystrobin residues were stable during all experiments.
研究了嘧菌酯、嘧霉胺、咯菌腈和氟啶胺在温室番茄上的消解情况。在收获前间隔期，除咯菌腈外，农药残留量均低于意大利规定的最大残留限量。通过模型系统研究的消解机制表明，嘧霉胺残留量的降低是由于共蒸馏和光降解，氟啶胺是由于光降解，咯菌腈是由于蒸发和共蒸馏。在所有实验中，嘧菌酯残留量均保持稳定。
