About:
I have always been interested in exploring plant pathogenic fungi and this led me in studying the mycotoxigenic fungi /Fusarium verticillioides/ and /Aspergillus flavus/. In the past, I was involved in projects focusing on the biological control of /F. verticillioides/ and rapid detection of fumonisin-producing /Fusarium/ species in corn. Recently, I conducted a study on the interactions between /A. flavus/ and stored-grain insect pests in conventional and Bt maize while also noting their effect on aflatoxin contamination. Other than these two molds, I also worked on different fungal pathogens attacking corn, sorghum, and papaya in the field and during postharvest. My current research involvement is on the detection of fungicide resistance isolates on selected vegetable and fruit crops. I intend to focus on the etiology and management of postharvest diseases on grains and fruit crops in future research projects.
