[81]-116. : ill. ; 24 cm. Responsibility: Maria Brömmelhues. Abstract: A series of experiments was carried out at the Bonn Agricultural College to determine the reciprocal effects of contact between cultures on biomalt agar and wheat extract solution of Ophiobolus graminis [Gaeumannomyces graminis], Cercosporella herpotrichoides [Pseudocercosporella herpotrichoides], Fusarium culmorum, Helminthosporium sativum (Cochliobolus sativus), Cladosporium herbarum, Alternaria (?) tenuis, Penicillium sp., Mucor sp., and Bacillus coli.It was shown by soil inoculation tests on Heines Kolben [Club] wheat seedlings in pots that O.graminis causes the most severe damage on plants previously exposed to four weeks' infection by most of the above-mentioned fungi, especially C.herbarum, the virulent toxins produced by which evidently increase susceptibility to the first-named pathogen.On the other hand, plants grown in soil simultaneously inoculated with O.graminis, H.sativum, and P.suffered less than those infected by the first-named alone, though the weakly antagonistic forms A.sp., M.sp., and especially C.herbarum, similarly applied, increased the injury caused by O.graminis.
