Fungal disease i.e.,chocolate spot (Botrytis fabae Sard.)and rust (Uromyces vicia fabae (Pers.) Schart) are the most destructive diseases of faba bean and causes considerable dramatic damage losses on faba bean yield worldwide Therefore, the use of plant nutrients (leaves fertilizers) i.e., Ascobein(As), Citreen(Ci) and Potassen (Po) to both diseases (chocolate spot and rust) in Vicia fabae ,gave evidence for controlling these diseases. Results showed that ,spraying faba bean plants with As+Ci+Po significantly decreased chocolate spot disease with 3.5% and 3.81% while ,rust was by decreased 5.2% and 5.77% for the two growing seasons 2010/2011 and 2011/2012.                                                              Total chlorophyll reached   to the maximum values when using Potassen (1.933mg/g f.w.) while ,As+Ci+Po as combination revealed the most superior effect on total phenolics compounds .All treatments were found to be most effective in increasing growth characters and yield of faba bean.
