In small-scale experiments with cultivars of the naked oat (Adam and Abel), the effect of Oscinella frit and fungi on the occurrence of black and rotten grains was studied. Analyses indicated significant effects of the insect and the fungi Alternaria and Fusarium on the occurrence of black and rotten grains. In the panicles of plants isolated for the whole period growing the number of black and rotten grains was 0.95 % whereas in those growing outside 4.2 %. Alternaria and Fusarum were prevailing among the surface fungi, the first on reaching 16.54 % on the black grains and 9.85 % on the healthy grains and the second one 9.76 and 5.09 %, respectively. The germination of black grains was reduced by 48 %.
