The influence of fungus Septoria tritici on winter wheat (Triticum aestivum) cultivars ‘Polis´ka 90’ and ‘Stolychna’ yield formation and plant development, as well as protective role of oxalic acid were studied in the field experiment. It was shown that treatment by oxalic acid decreases the infected square of flag leaves, ears and stems in both varieties that normalized plant development and reduced the yield loss. The usage of elicitors is the way to induce the plant immunity of cereals and minimize the pesticide pollution of the environment.
