The distribution and harmfulness of root rot of barley is studied. The disease is widespread throughout the vegetative period of spring barley and covers 30.0% of plants during the germination period, 40% – tillering period and 60.0% during the milky-wax ripeness of plants. The intensity of the disease is in the range from 10.0% to 15.0%, depending on the phase of development.

The influence of the damage of barley on the elements of the structure of the crop and on the biometric indices of plants was determined.

Growth and development of spring barley plants significantly slowed down with increasing degree of their damage, as evidence shows with strong disease development - 75-100% height of the plant decreased by 20,3-24,45cm, compared with healthy (90,25cm). A similar pattern was observed in relation to the decrease in the length of the root and its mass, depending on the degree of development of root rot.

The defeat of plants by root rot in our studies significantly influenced the elements of the structure of the crop. The most sensitive element of the structure of the crop that reacts to the pathogen, is the number of seeds from one plant. So, with the development of the disease 25 and 50%, this indicator decreased by 2.95 and 5.40pcs. Respectively, and at 75 and 100% - at 8.40 and 9.95pcs.
