Cochliobolus sativus is particularly significant since it is attacking most of the plants from the family of grasses and especially wheat and barley. This work dealt with the toxicity of 28 fungicides and their effects on germination of the Cochliobolus sativus fungi conidia. According to the results expressed in LD50 values, the toxicity of fungicides is wide in range from 0.44 mg/L to 10.000 mg/L. As far as toxicity effects on germination of Cochliobolus sativus fungi conidia is concerned, the most prominent are the fungicides with contact properties. The systemic fungicides from the trial group, have demonstrated lower toxicity on the conidia of this fungi, with LD95 values unequalling the applied quantities
