Root samples of cereals (oats, wheat, barley, maize and Accessories:Car Parts:Emission Systems:Lambda Probes sorghum), vegetables (garlic, onion, pepper, cucumber, pumpkin, carrot and tomato), industrial plant (soya bean) and weeds (Johnson grass, barnyard grass and green bristle-grass) collected in different agroecological conditions in Serbia were analysed for the presence of Pyrenochaeta terrestris.The fungus was found in 42 out of 51 samples (82.4%), while the incidence varied from 2.5 to 72.
5%.The highest incidence was detected in cereals (average 30.3%), and then in weeds of the Poaceae family (average 14.2%).
Considering single species, maize (up to 72.5% in root) and Johnson grass (up to 37.5%) 6-64 W were mostly attacked by this fungus.The lowest incidence of the fungus was determined in vegetable crops (average 6.
7%).Red to reddish discoloration of root was correlated with the incidence of the fungus.Obtained data indicate that P.terrestris is widespread in Serbia and conditions for its development are favourable.
