Abstract: This study was to investigate the incidence of seed-borne fungi on the groundnut seeds isolate and identify the seed-borne fungi associated with some of groundnut seeds and obtain information on the pathological effect of these fungi on the peanut seed germination. The results of these investigations revealed the existence of four notable seed-borne fungal pathogens, specifically A. niger, A. flavus, A. tamre, and one Aspergillus pp., in the designated research area. A. niger was identified as the predominant fungus affecting groundnut seeds among these pathogens. This finding suggests that the presence of A. niger might inhibit the growth of other fungi through competitive interactions in the environment. Previous research by Ohave. The findings are consistent with the results of my study, which demonstrate that these fungi play a role in causing pathological effects on groundnut seeds, resulting in issues such as seed shriveling, discoloration, and decreased germination rates due to seed-borne fungal infections. The conducted study emphasizes the importance of treating seeds purchased from markets with fungicides prior to planting to prevent seedborne diseases like seed rot, decay, and other related pathologies. Furthermore, it is very important to take steps to reduce the spread of seed-borne pathogens and the production of mycotoxins in groundnut seeds by improving storage conditions, which include maintaining low temperatures, humidity levels, and moisture content. Additionally, preventive measures should be implemented to avoid damage during post-harvest processes at storage and during the sale at the market.

Abstract: This study was conduct to investigate the efficiency of certain botanical smokes against Varroa mite. In the field, four botanical smokes (Cordia Africana, Terminallia, Tobacco, Barley + Olea leaf smoke) and two control groups (Sticky bottom board only and without sticky bottom board and untreated) were tested as control agents against the parasite mite V. destructor. Throughout the treatment period, each colony received the treatments of each tested substance. Data showed that among all four tested treatments, tobacco leaf smoke followed by Terminallia leaf smokes were effective in controlling Varroa as they had an efficiency of 73.2%, 62.59%, respectively. These compounds also found to be helpful in the reduction of varroa mite load as they showed percentage of reduction of mite infestation were 63.59% and 49.84% respectively. As a result, these smokes could be employed as part of standard beekeeping procedure while working with colonies.
