In today's present, the trend is to use fungicide for the control of fungi, which is harmful for the human consumption. The development of pest resistance and problems of environmental pollution have accompanied excessive reliance on pesticides. These problems can be avoided or minimized by using the natural material products such as medicinal plant extracts.The present studies indicated that Allium sativum extract was able to inhibit the growth of two bacteria (Escherichia coli and Staphylococcus aureus) and two fungi (Aspergillus niger and Alternaria solani) studied.
