EFFICIENCY OF METHODS USING PREPARATIONS OF FUNGITOXIC EFFECT AGAINST ROOT ROTS OF BARLEY IN URALS
Barley is an important food, fodder and industrial crop. Spring barley is cultivated everywhere in Russian Federation: from the Polar region to the southern borders. Spring barley has a great demand among the cereal crops. The grains of the barley used as a concentrate animal feed for all species, commonly it is used for fattening pigs. Coffee substitutes and the malt extract are widely used in industry and they are produced from barley grains. Barley is an excellent raw stuff for the brewing industry. Barley straw surpass in nutritiousness rye straw and wheaten straw; steamed it is used as an animal feed. In southern areas barley is cultivated on a green fodder and hay mixed with a vetch, peas, a peavine and the other cultures. In this article the author examine the combination of the plant protection techniques which are aimed at increasing the yield of malting barley in the Urals. The authors consider the combination of two chemical preparations of the fungitoxic effect. Used preparations are a legal preparation albite, TPS and experimental alkamon OS-2, PS. In this article describe the influence of the preparations on root rot sickness rate of brewing barley on various organ receptors. The conducted researches show the perspective of an experimental preparation. Alkamon OS-2, Ps effectively prevents the root rot development throughout the season, and in some cases even more effective than preparation albite, TPN. Preparation alkamon OS-2, PS demonstrates the biological efficiency of 37 to 49 % in different phases of barley development. A different combination of methods of application of preparations provided a productivity increase from 0.28 to 0.96 t/ha grains.
