Hops are grown on one month 15-20 years or more and it does not have such aboveground or underground organs that are not damaged by pests or diseases. During the growth of hops can damage about 20 species of various diseases. In recent years there is a tendency toward the growth of hop infestation by fusariose, Plenodomus or dry rot, buckshot rot and, in part, by bacterial canker. In hop growing chemicals are still being used frequently for plant protection, and their systematic application results in environmental pollution, emergence of resistant strains, pathogenic populations and pests. To study the possibility of using biological fungicides against root rot in hops growing technology. In the experiment a set of methods was used: field and laboratory – together with visual observations; calculation and comparative; mathematical-statistical using dispersive and correlation-regressive analysis. To determine the level of propagation of root rot and determine their severity, systematic inspections of hops were carried out in accordance with generally accepted methods. Soil excavation and analysis of the root system of hops in the Zhytomyr region found that 44.9% of the area hop gardens have signs of root rot, including species composition which occupies 90% of Fusarium. The possibility of using the biological drug Hetomik to protect plants hop Fusarium root rot, reduce thinning hop gardens and improve their performance. Entering into the soil, using the method of watering horseradish hops, the preparation of Hetomik reduces the contamination of hop hives by root rot on average by 0.2-0.4 points, and their spread by 5.0-10.0%
