., 2003). Other approaches include integration with other control strategies
such as cultural procedures and chemical applications (Whipps, 2001; Someya
et al
.,
2007) and use of endophytic bacteria and fungi which may exhibit different patterns of
behaviour to those found external to the plant (Wulff
et al.
, 2003; Sessitsch
et al.
, 2004).
Thus, understanding more about the natural ecology of any potential BCA may enable a
more rational approach to production and use (Whipps, 1997b).
In conclusion, despite legislation hurdles and perceived frequent inconsistency of
effect, more BCAs are on the market than ever before. Much is known about the way
they work and this knowledge continues to increase. Often, the market for BCAs is small
as they generally have a restricted host range, but some are beginning to have global
signifi cance which bodes well for sustainable disease control in the future as chemical
pesticides become scarcer.
