Design and management of integrated vegetable production systems emphasizing soil quality and disease suppression; beneficial use of organic wastes.


Research Interests
Link to ROTBUSTERS! A web site about SWEET CORN DECLINE SYNDROME  Sweet corn decline syndrome emerged as a significant disease in the Willamette Valley of Oregon in the 1990’s. Root rot has been implicated as a major player in this disease complex, but crown rot and nodal darkening may also contribute to this syndrome.
