Deborah Fravel
Research Plant Pathologist
Because
of its role in destruction of ozone, the use of methyl bromide as a soil
fumigant is being phased out. Dr. Fravel has
initiated studies to discover alternatives for methyl bromide, particularly
for the control of Fusarium wilt of tomato. She
and colleges have found beneficial fungi to control Fusarium wilt. In addition to finding out how these agents work,
Dr. Fravel is studying the ecology of the pathogen and the biocontrol
agent. She also studies biocontrol of Verticillium
wilt.
