Preventive seed application of an Actinomycete, Trichoderma viride, My
rothecium verrucaria or Trichoderma pseudokoningii reduced seed-borne
Drechslera teres infection of barley coleoptiles by 90%, 87%, 79% and
76%, respectively. Moreover, leaf infection after artificial inoculati
on was decreased by 87%, 84%, 79%, 77% and 71% when the Thibaut cultiv
ar had been previously treated at the three-leaf stage with Myrotheciu
m verrucaria, Actinomycete, Trichoderma sp., Trichoderma viride or Tri
choderma pseudokoningii, respectively. These antagonists also reduced
conidia formation on straw colonized by D. teres.
