Modelling the fate of pesticides in innovative cropping systems disigned to reduce the use of pesticides

EAAgroSupINRAGESTAD; The objective of this work was to assess and compare the ability of three pesticide fate models (MACRO, PEARL and PRZM) to simulate the concentration in leachates of pesticides applied in different conventional and innovative cropping systems. The test of the models was based on measurements of water flows and pesticides concentrations done in two French experimental sites. The results showed that MACRO was the most efficient model to simulate the amounts of percolated water and the concentrations of pesticides used in the various cropping systems
