Stocks of imported gladioli which originally contained a proportion of scabbed corms showed very little carry‐over of the disease during the eight growing seasons 1938‐45. Carry‐over was greatest on ground where gladioli had been planted for several successive years. The incidence of the disease was greatest in the hot summer of 1940. Treatment with mercurial fungicides just before planting time gave good control. Two non‐mercurial fungicidal dusts were less effective.
