AB  - Fungi such as Aspergillus niger (brasiliensis)
Aspergillus flavus, Alterneriadia nthocola, Curvularia
lunata, Curvulari apellesecens, Fusarium oxysporum,
Fusarium equiseti, Microphomina phaseolina, Rhizopus
stolonifer, Penicillium digitatumare associated with heavy
losses of seeds, fruits, grains, vegetables and other plant
products in transit and storage rendering them unfit for
human consumption. The research sought to identify
fungal pathogens of groundnut rot in storage in Hong
Local Government Area of Adamawa State, Nigeria a
major groundnut producing area. A survey was carried out
using random sampling on incidence of groundnut rot in
the seven districts of Hong Local Government Area
in the month of July 2016. Isolation and identification,
frequency of occurrence, virulence as well as effect of
pathogens on germination of groundnut seeds and
seedling growth were carried out. Incidence of rot
occurred in all 7 districts with the highest in Hong, Hildi
and Gaya, pathogens associated with the rot were
identified as follows; Aspergillus niger (brasilensis)
Aspergilus flavus, Penicillium chrysogenum, Rhizopus
stolonifer, Paecilomyces lilacinus, Pseudallescheria
boydii, Cylindrocarpon lichenicola and Scedosaporium
prolificans. The frequent occurring fungi were Aspergillus
niger (brasilensis) and Aspergillus flavus while the most
virulent was Aspergillus flavus. There was significant
reduction in seed germination and seedling growth at
99.99% probability level for both the Valencia (Kampala)
and Peruvian (Kwathrumthrum) from 33.33% for uninoculated
to 11.00% for inoculated. Proper storage
practices to reduce groundnut rot as well as enhance seed
viability are therefore, suggested
