The Impact Of A Hexaconazole Fungicide On Agronomic, Biochemical Parameters And Yield Components Of Green Beans Phaseolusvulgaris Cv. Djedida

Résumé: The use of synthetic phytosanitary products has proved to be very effective in controlling crop diseases and pests in a significant number of cases, however, many studies and studies concern the presence of these molecules in the soil, contamination of the waters we have to say confirmed the degradation of living ecosystems. The aim of this work is to verify the effect of the fungicide Hexaconazole on agronomic, biochemical markers and enzymatic activity of a legume green bean Phaseolus vulgaris, cv. Djedida. Four treatment doses were chosen with control namely Dose1 (0.4ml/l), Dose2 (0.8ml/l), dose3 (1.2ml/l), Dose4 (1.6ml/l). The obtained results show that all variables studied agronomic, physiologic and enzymatic are relatively stable for plants treated with low doses0.4ml/l and 0.8ml/l. against, the plants treated by highest doses D3 and D4 recorded the lowest values. The dose effect is decisive and proportional to the applied level. The analysis of the mechanisms of response to oxidative stress or oxidative stress-xenobiotic interactions may therefore provide a better understanding of the processes of response to xenobiotic.
