Efforts in our laboratory are focused on characterization of
host-pathogen interactions and biological control of vegetable crop diseases.
We undertake various research projects dealing with sustainable/integrated
disease management in organic and conventional vegetable production systems; the
development of biopesticides from fungal metabolites, biochemical/molecular
mechanisms of biotic and abiotic stress resistance/tolerance associated with
plant growth promoting beneficial microorganisms in vegetable crops. Other
areas of interest include mushroom cultivation, technologies for seed treatment
and seed health testing and broad-sense plant biotechnology.
Mentor undergraduate students; Advise graduate students and
serve on Thesis/Dissertation Committees; Adhoc reviewer for HortScience, African J. of
Biotechnology, Bioresource Technology, Crop Science, Crop
Protection, J. of Crop Improvement and others; Member, editorial board
for the Journal of Waste Conversion, Bioproducts and Biotechnology,
and advise and train small vegetable growers on sustainable integrated disease
management (IDM) tactics for vegetable crops.
