1986
Rudnick, M. (Pflanzenschutzamt des Landes Schleswig-Holstein, Kiel (Germany, F.R.))
Немецкий. 1985 in Schleswig-Holstein winter wheat was infested by the Cephalosporium leaf stripe disease, hitherto not described from this land of the Federal Republic of Germany. The symptoms were caused by the fungus Hymenula cerealis Ellis et Everh. (stat. conid. Cephalosporium graminearum Nisakado et Ikata), a soil-borne pathogen which invades through damaged roots. The first scattered symptoms were detected in the first decade of July, in the last decade of July the epidemic was manifest (Fig. 1-3). Narrow returns of winter wheat in crop-rotation, accumulation of inoculum during the cool and rainy autumn, early sowing, and damage of the roots by freezing-up of the ground (uprooted by frost), provided opportunity for this calamity
