Ma. Bashar et B. Rai, ANTAGONISTIC POTENTIAL OF ROOT REGION MICROFLORA OF CHICKPEA AGAINST FUSARIUM-OXYSPORUM F SP CICERI, Bangladesh journal of botany, 23(1), 1994, pp. 13-19
Antagonistic potential of root-region microflora of chickpea (Cicer ar
ietinum L.) against Fusarium oxysporum f.sp. ciceri was evaluated thro
ugh colony interactions and the effects of their volatile and non-vola
tile metabolites. Trichoderma harzianum T. viride, Streptomyces rochi
(S-1) and S. rimosus were proved to be strong antagonists. Significant
colony inhibition of the pathogen, was noted due to colony interactio
n with species of Aspergillus, T. harzianum, T. koningii, T. viride, S
. rochi (S-1), S. rimosus and Bacillus subtilis (S-2) and due to non-v
olatile metabolites of A. luchuensis, A. niger, S. rochi (S-1) and S.
rimosus and the volatile metabolites of Penicillium citrinum P. decumb
ens, P. oxalicum, T. koningii, T. viride, S. rochi (S-1) and S. rimosu
s. Considering all the parameters in totality T. harzianum T. viride,
S. rochi (S1()) and S. rimosus were noted as the most potent antagonis
ts against the test pathogen.
