ABSTRACT:

An experiment was carried out at the Crop Science Laboratory of the University of Agriculture, Makurdi to isolate and identify disease causing organisms in groundnut seeds and determine the levels of damage. The findings from this study revealed six fungal organisms viz Aspergillus tamari, Aspergillus niger, Rhizopus spp, Aspergillus flavus, Lasiodiplodia spp and Fusarium spp. were present. Rhizopus spp and Aspergillus flavus had the highest frequency of occurrence among the organisms causing seed deterioration. They had 89.17 and 75.67 frequency of occurrence respectively. Also, shriveling of seeds, reduce or small seeds, rottening of seeds, insect damage, white and black stains were found to be the types of damage of groundnut seeds in Benue State. In general, the organisms that cause deterioration of the seeds have the following percentage of occurrence. A. niger 51.56, Fusarium sp. 5.0 and Rhizopus spphas 89.77%.
