Abstract:
In the present studies effectiveness of antagonistic fungi viz.
Trichoderma viride were evaluated against
Meloidogyne incognita on tomato. The application of
T. viride significantly increased shoot weight and decreased root weight of tomato in a dose dependent
manner. Doses of 6 gm/kg soil as soil treatment and 9x10
8 cfu/ml as bare root dip treatment showed maximum increase in shoot weight and decrease
in root weight. On the other hand, the antagonistic fungi caused significant reductions in number
of galls, egg masses, eggs per egg mass and reproductive factors of
M. incognita in a dose dependent
manner. The fungi caused the maximum reductions in these parameters at two highest doses of 6 gm/kg soil as soil treatment and 9x10
8 cfu/ml as bare root dip treatment. It is, therefore, concluded from the present evaluation that the indigenous isolates of
T. viride have the potential to control
M. incognita as both the treatments viz. soil application and bare root dip treatment.
