This study was carried out in Yola and Mubi both of which are located in Northeastern Nigeria to evaluate the efficacy of some plant extracts on the different manifestations of bacterial blight caused by Xam on different cotton varieties. The study was also intended to examine the reaction of these treated varieties to the disease with a view to identify the most effective plant extract. Results revealed that SAMCOT-8 and SAMCOT-12 varieties have moderate resistance to Xam haven recorded least mean incidences of vein blight, black arm, boll blight and lowest percentage boll rot and higher yield of seed cotton in both locations. Results further revealed the most effective plant extract to be A. sativum (50%) which consistently recorded the lowest mean value of 6.00% and 9.33% seedling blight, 4.67% and 30.00% vein blight, 10.66% and 10.00% black arm, 20.66 and 12.66 boll blight and yield of 403.89 kg ha-1 and 921.25 kg ha-1 in Yola and Mubi respectively. From these findings, it can be inferred that the various cotton varieties and plant extracts at 50% concentration tested on Xam showed promising prospect for management of bacterial blight of cotton. It is hereby suggested that SAMCOT-8 and SAMCOT-12 with A. sativum (50%) and A. cepa (50%) should be put to further field trial in these locations to determine their effectiveness in the management of Xam.
