3.1 Bioefficacy of rhizobacteria against M.
incognita infecting tomato
Nematode infection was significantly reduced in rhizobacterial
treatments as compared to untreated. An average of 265.80 root galls per
root was observed in control treatment which reduced significantly
(P<0.05) in presence of rhizobacteria isolates B.
pumilus (42.60), B. megaterium (41.80), B. subtilis(22.50) and B. cereus (48.75) (Table 2 ). Thus the
reduction was significant on application of rhizobacteria. The average
number egg mass per plant were 165.80 in untreated control which reduced
in presence of B. pumilus (36.70), B. megaterium (34.25),B. subtilis (15.45) and B. cereus (44.60). The effect of
at for B. pumilus , B. megaterium , B. subtilis andB. cereus , but was significantly more for B. subtilis .
This was also evident in the number of eggs per egg mass and
reproduction factor on nematode in B. subtilis treatments. The
effect of B. pumilus , B. megaterium , B. subtilisand B. cereus was for with Velum Prime with respect to reduction
in average number of galls, egg mass per plant, eggs per egg mass and
reproduction factors of nematode. However B. subtilis was found
to result in significantly (P < 0.05 ) higher reduction
in the above mentioned parameters of nematode infection (Table 2).
