    Study of the effect of a fungicide "the tachigazole" on some indicators of soil biological activity

    ABSTRACT
    This study tests the impact of a pesticide molecule (hymexazole) on, on the one hand, the physio-biochemistry of hard wheat Triticum durum Desf. (Poales Poaceae) and on the other hand, the indicators of soil biological activity. To do this, the analysis has focused on total proteins, proline, the total carbohydrates and total chlorophyll of wheat leaves. Total carbon and soil organic matter have been also determined. Results reveal that the levels of total chlorophyll are practically identical in the presence of different doses of the fungicide in comparison with those of the control dose. The contents of other parameters (total proteins, carbohydrates and proline) are slightly different from those obtained for witnesses doses. Finally, the analyzed soil samples show that the values of the total carbon are higher and exceed the standards in the samples treated with fungicide.
