Trichoderma strain antagonism evaluated in vitro using Bell’s scale [39], considering the invasion of the surface.

Scale	Antagonistic Ability
1	Trichoderma completely overgrew the P. cinnamomi and covered the entire medium surface.
2	Trichoderma overgrew at least two-thirds of the medium surface.
3	Trichoderma and the P. cinnamomi each colonized approximately one-half of the medium surface and neither organism appeared to dominate the other.
4	P. cinnamomi colonized at least two-thirds of the medium surface and appeared to withstand encroachment by Trichoderma.
5	P. cinnamomi completely overgrew the Trichoderma and occupied the entire medium surface.
