Abstract

The genus Azotobacter and Bacillus have a
potential to atmospheric nitrogen fixation, mineral elements
solubilization and producing a group of stimulator of vegetal
growth substances. In addition, Bacillus is recognizing by its
antagonistic activity. The reasons justify its selection with
actives principles of biofertilizer products. The presence
of fungus diseases in vegetable cultures is a problem for
Cuban agriculture. The objective of the present work was
to evaluate the antagonistic activity of Azotobacter and
Bacillus strains against fungus that caused diseases in
vegetables cultures. For those were employed Fusarium
chlamydosporum, Corynespora casiicola and Cladosporium
oxysporum. All strains belong at the INIFAT collections. For
the development of work, “Dual Culture Bring” Method was
used with permitting the selections those to possess previous
activity and descript, in turn, principle affectations caused to
fungi structures. Results emit that inside of two genus exist
strains that inhibit the micelial growth. Among strains of
Azotobacter, five result promissory against Cladosporium
oxysporum, two respond to Fusarium chlamydosporum
and only one was effective against Corynespora cassiicola.
The activity shows for Bacillus genus is major. In this case,
two strains show activity against Corynespora cassiicola,
six against Cladosporium oxysporum and eight against
Fusarium chlamydosporum. Highlight the finished that
exists strains of Azotobactersp capable of inhibit more than
one fungi species, which results very new for being quoted
few times the genus activity against vegetable pathogens.
