Abstract

Phloem necrosis in elms, caused by the virus Morsus ulmi Holmes, has been found at Rolling Fork, Mississippi, 60 miles northwest of Jackson and 47 miles north of Vicksburg, in the Delta hardwoods area. It was first reported in Mississippi in 1941, when it was found at Jackson, and it appeared in the northeastern part of the State in 1945.
