also inhibits growth of other pathogenic fungi including T. basicola
and Verticillium dahliae (Howell and Stipanovic, 1979). In field trials,
a soil drench of Burkholderia cepacia improved plant stand in
R. solani infested soils, possibly due to the production of growthinhibiting
antifungal compounds (Zaki et al., 1998). Trichoderma
spp. including T. harzianum and Trichoderma virens have been
identified as biocontrol agents against R. solani
