Common bean (Phaseolus vulgaris L.) is the most consumed legume worldwide, with a commercial value surpassing that of all other legume crops combined. Seed-borne fungi cause at least 10% loss in common bean. Standard blotter (SB) and agar plate (AP) techniques were used to identify seed-borne fungi associated with common bean seeds. Thirty-two fung...

An Alternaria eichhorniae islolate (#5) pathogenic to water hyacinth was discovered in Egypt in 1984. This fungus appeared to be host specific and capable of severely damaging and thus suppressing the weed. The major constraint to its use as a biocontrol agent—the need for a long period of dew—has been overcome through formulations using oil emulsi...
