A survey was conducted in two Local government areas (Girie and Yola-south) of the central
region of Adamawa state during the months of August and September, 2019. 16 soybean fields
were surveyed (random sampling) for recording the severity and incidence of bacterial blight of
soybean. At (P=0.05), In Girie local government area, result showed high percentage severity in
GREF-5 and GREF-8 having the highest value (85%) respectively, the highest percentage
disease incidence was recorded in GREF-5 (79.4%). Percentage disease incidence and severity in
Yola-South was also high with YLSF-2 having the highest value (71.3%) and (85%) respectively.
In the central geopolitical zone of Adamawa state, the Percentage incidence is moderate with
mean value of (50.0%). Percentage severity is generally high in the zone with mean value of
(65.6%). In conclusion, the research indicate a high percentage disease incidence and severity of
bacterial blight of soybeans in the central geo-political zone of Adamawa state.
