were observed in untreated control field (Fig. 6). This was probably
due to the air borne nature of the Alternaria conidia. 26.53 ± 2.93%
and 54.25 ± 3.55% extents of disease severity were noticed in
untreated control fields after 60 and 90 days of planting. On the
other hand no disease symptoms were recorded for the first
30 days in both the fields treated with VBK1 and VBC7. Only
11.69 ± 1.25% and 15.22 ± 2.64% extents of disease severity were
recorded after 90 days in the fields treated with VBK1 and VBC7
respectively.
