Abstract: A study for the rot of Mango fruit was carried out in three markets of Yola North Local Government of Adamawa State (Jimeta Modern market, Jimeta shopping complex and Jimeta old market) in April, 2015. Also the effect of crude water extracts of neem on the rot control was carried out. The following isolates Botrytis cinerea, Aspergillus flavus and Aspergillus niger were identified and proven through pathogenicity test to be the pathogenic. Out of a total sample size of 72 fruits (24 fruits/market) there was an average rot incidence of 33.3%. The highest pathogen incidence was in Jimeta Modern market (36.82%) while the least was in Jimeta old market (27.93%). Severity of mango fruit rot in the markets showed that Jimeta Modern Market was moderate (29.03%), Jimeta Shopping complex was also moderate (29.04%) while Jimeta Old market was high (41.93%). Control trials (invitro and invivo) on Botrytis cinerea, Aspergillus flavus and Aspergillus niger had 2.71mm, 2.30mm, 0.90mm rots (invitro) respectively. The neem leaf extract was highly effective compared to control set up (P=0.0001).
