seed treatment if the treatment is combined with T.
virens. Further studies are needed to explore the
possibilities of commercialisation of this isolate of T.
virens with major emphasis on delivery system, shelf
life, stability and efficacy of the biocontrol agent.
The prospects of this are good, considering that a
relatively simple preparation of the antagonist was
highly effective in the field. In the end, farmers
choice on the control options will be highly influenced
by the prevailing costs and benefits of competing
control methods, so economic feasibility is another
parameter that should be taken into consideration.
Once commercialised, effective, economic and
environmentally benign control of gladiolus corm rot
and wilt may become a reality for gladiolus growers.
