There is an increasing consumer demand for quality food, a concept which mainly
involves the availability of disease-free products and harmful to human health
chemical waste, which is why the need for new options for sustainable management
arises broccoli crop against the causative pathogen damage in inflorescence. The
disease caused by the phytopathogenic fungus Alternaria spp is a major cause of
damage to broccoli cultivars. Field sampling and laboratory investigations were
conducted; field soil samples randomly taken broccoli cultivars, plant samples showed
signs of being that infected with Alternaria spp collected. In the laboratory stage it
proceeded to the isolation, identification and in vitro of Bacillus subtilis strains for the
control of Alternaria spp tests; the antagonistic capacity was measured using the scale
Bell, the results indicated that the strain ATCC 6633 and strain AB-4 identified and
characterized as Bacillus subtilis subsp. licheniformis, they showed antagonistic
activity with a value of 21.58% class 2 as measured Bell, thus determined the potential
of Bacillus subtilis as biocontrol good against Alternaria spp. |
