Charcoal rot disease caused by Macrophomina phaseolina on cowpea results in yield losses with serious socioeconomic implication. Sixteen isolates of M. phaseolina were isolated from cowpea diseased plants collected from different locations in New Valley Governorate. All obtained isolates able to attack cowpea plants (cv. Balady) causing charcoal rot on the basil stem with various degrees of diseases severity. M. phaseolina isolate No. 14 was the most aggressive ones in this respect causing 85.8% charcoal rot.

Potassium silicate (KS), propyl gallate (PG), hydroquinone (HQ) and salicylic acid (SA) at 1,5 and 10 mM were used in this investigation as promising methods for controlling such diseases in vitro and in vivo. Results illustrated that all tested chemical inducers were lit... view more»
