Postharvest diseases caused by pathogenic fungi result in major
losses of fruits and vegetables, and synthetic chemical fungicides
are the primary means to application at present (Spadaro & Gullino,
2004). However, synthetic chemical fungicides are potentially
harmful on human health and the emergence of pathogens which
are resistant to these chemicals (Holmes & Eckert, 1999). Moreover,
public concern over the indiscriminate use of synthetic fungicides
has been growing. Thus, it is significant to develop new
alternatives for disease control (Tian, 2006).
