The Grecos were protagonist in the violent conflict about the Palermo fruit and vegetable wholesale market that was moved from the Zisa area to Acquasanta near the port in January 1955, disturbing the delicate power balances within Cosa Nostra. The Acquasanta Mafia clan tried to muscle in on the protection racket that traditionally belonged the "Mafia of the Gardens" — such as the Grecos and Cottone — because it now fell under their territory. The bosses of the Acquasanta Mafia clan, Gaetano Galatolo and Nicola D’Alessandro, as well as Francesco Greco from the Ciaculli clan, a major wholesaler of fruit and vegetables, were killed in a dispute over the protection rackets.
