Dr. Michael V. McKenry is a University of California, Riverside nematologist located at the Kearney Agricultural Center in Parlier.  His primary research focus is the damage and control of nematodes attacking perennial crops. He has been involved in the development of pathogenicity data for tree fruits and vines with nematodes such as Pratylenchus vulnus, Meloidogyne spp., and Mesocriconema xenoplax. He has been involved in screening tree and vine rootstocks for resistance to various nematode species and the development of nematode host lists for cover crops. Dr. McKenry is involved in the use of plant extracts as a method of nematode control. Complex diseases such as Bacterial Canker Complex of Prunus spp. and the general replant problem of tree and vine crops are also of major interest.
