- PATHOLOGY OF WHEAT (Triticum aestivum L.) IN SOUTH WESTERN NIGERIA: Wheat cultivation is not traditional to South Western Nigeria. However, the prospect of its cultivation as a rain-fed crop was the focus of my research into the pathology of the seed and whole plant. My research identified the specific fungal pathogens of the different diseases of rain-fed wheat as well as the pathogenic potentials of the seed-borne mycoflora. Interfungal interactions among some of these pathogens were revealed while two control options; plant ash and synthetic fungicides were elicited for the management of rain-fed wheat disease in South Western Nigeria. Ref: (Articles 2, 3, 4, 8, 9, 13 & 22).
- PATHOLOGY OF SESAME (Sesamum indicum L.) IN SOUTH WESTERN NIGERIA: Sesame is a crop that has just been introduced to South Western Nigeria. Current research efforts in this regard served to give basic information. My research efforts have served to identify major field diseases of sesame (and the impact of climatic factors on disease development). Appropriate planting dates were determined with reference to incidence and severity of this disease. A new easily adoptable incidence and severity index was developed for this disease while the management of the disease through the use of plant extracts, synthetic fungicides and intercropping were achieved in my studies (Ref. Articles: 5, 6, 7, 16, 21, 26, 27 & 28). My research into the seed pathology of the crop also revealed a major impediment to seed health studies – ambiguous record of seed colour. Interfungal interactions on the sesame seed has been revealed by my studies, as a bad tool for further insight into the seed pathology of sesame seed disease management through salt density and plant extracts treatments were also achieved by my research (Ref: Articles 15 & 25).
- SEED HEALTH AND MYCOTOXINS: My research into the health of pigeon pea (Cajanus cajan L.) and maize (Zea mays L.) and other crops have served to establish the presence of mycotoxins (Aflatoxin B1 and Fumonisin B1) and mycotoxigenic fungal species in seed as well as their rapid detection through a simplified medium. Early harvesting (between 30-35 Days after Tasselling) of maize was discovered to prevent infection of seeds by Fusarium monilliforme, F. graminearum, Botrydiplodia theobromae and Dreschlera maydis. Studies also showed that pigeon pea stored in jute bags or iron bins for 3-5 months are free from aflatoxin just as oven or smoke drying of ‘egusi’ melon (Colocynthis citrullus L.) seeds reduced Aspergillus flavus contamination. (Ref: Articles 1, 11, 14, 17, 18).
- MYCOLOGY, BIOCONTROL AND OTHER STUDIES ON TOMATO, (Lycopersicon esculentum L.) COCOA (Theobroma cacao L.) AND COWPEA (Vigna unguiculata L. Walp): My research efforts also established the synergistic value of mycorrhizal fungi Glomus Spp to tomato seedlings as well as the potential of microbial antagonists (Bacillus spp and Aspergillus spp) isolated from tomato fruit and leaf surfaces to reduce tomato fruit rots. The efficacy of some plants extracts in the management of tomato fruit was established by my studies. The susceptibility of local cocoa germplasm to black pod disease was evaluated in a study while the potential of bee-propolis and some plants extracts in the management of anthracriose disease of cowpea was established by my research efforts. (Ref. Articles: 10, 12, 19, 20, 23, 24 & 29).
