Research Interests / Job description
Soil borne pathogens in vegetables, flowers and peanut in the following topics:
1. Chemical control of soil borne pathogens. Chemicals: metham sodium, methyl bromide, 1,3 dichloropropene (Telone=Condor) and benomyl.
Pathogens: Verticillium dahliae, Sclertoinia sclerotioum, Fusarium oxysporum f.sp. dianthi, Pythium spp., nematodes and mites.
2. Ecology and epidemiology. Survival of sclerotia of S. sclerotiorum, Sclerotium rolfsii and microsclerotia of V. dahliae in semi-arid climate. Fusarium wilt in carnation (F. o. dianthi): distribution of the pathogen in soil, the relationship between inoculum and disease, and effect of cultivar resistance on wilt incidence and population densities on plants and in soil.
3. Developing greenhouse and field screening methods to evaluate resistant cultivars or lines. Effect of isolate source and daylight intensity on the pathogenicity of V. dahliae in watermelon and Fusarium oxysporum f.sp. dianthi
