Eight isolates of Thanatephorus cucumeris Frank (Dank) (Rhizoctonia solar?, Kuhn) isolated from sugarbeet seedlings and roots were multinuclate. Considering anastomosis, the isolates fell into two groups corresponding to AG-2 and AG-4. A greenhouse test was conducted to determine the effect of cotton, soybean, sugarbeet, beams and corn as crops preceding sugar-beet on Rhiroctonia seedling disease of the latter. All isolates of AG-2 and AG-4 showed different degrees in infection percentage and disease severity on seedling stage (15 and 30 days) on all,crops. Cotton, soybean and sugarbeet significantly increased pre- and post-emergence damping-off, while beans and corn were less conducive. Therefore, lower disease incidence in pre- and post-emergence stages could be obtained by not following cotton, soybean, or sugarbeet. Advantage of reduced damping-off in sugarbeet following corn in rotation is apparent.
