Abstract
Bean plants are subject to attack by Macrophomina phaseolina, which was isolated from different localities in Ismailia govemorate. It was frequently isolated from infected roots and less frequently from collected seeds. Nebraska bean cultivar was the least susceptible: Morgan cv. was moderately susceptible, while Xera cv. was the most susceptible. 7Wchoderma harzianum as a biocontrol agent and Plant guard as a biocide resulted in a great reduction in mycelia! growth of M phaseolina isolates (In vitro) and suppressed the disease in plants grown from dressed seeds or by soil drenching. The fungicides Vitavax and Rhizolex have completely prevented the mycelia! growth of tested M phaseolina isolates at 50 ppm. Benlate resulted in the same level of inhibition at 100 ppm. Vitavax reduced pre, post emergence damping-off and charcoal rot disease of Xera bean cultivar followed by Rhizolex and Benlate.
