In the present investigation, the plant height and fruit
yield were also increased in ANR-1 treated plants. Similar results
on increased plant growth due to application of Trichoderma
gamsii in cereals and legume crops [22]. The increase in plant
growth might be associated with secretion of auxins, gibberellins
and cytokinins.
The increase in biomatter production may be due to the
production of plant growth promoters or through indirect
stimulation of nutrient uptake and by producing siderophore or
antibiotics to protect plants from deleterious rhizosphere
organisms. Therefore, the antagonist T. harzianum (ANR-1) is
chosen to be the most promising bio-control agent for F.
oxysporum f.sp. lycopersici. On the base of present study the
bioagents of fungi, might be exploited for sustainable disease
management programs to save environmental risk.
