PRESERVATION AND IMPROVEMENT OF SHOOTS AS THE BASIS FOR FORMATION OF BARLEY PRODUCTIVE AGROCENOSIS

Abstract

The researches of Vial Trust, Lamatador and Vitutsit were carried out in Krasnoyrsk forest steppe. Vial Trust, Lamatador and Vitutsit were investigated in a field experiment on infected barley. So were tant mixes of Vial Trast+Taboo in regulated doses recommended for creation of productive agrocenosis. The preparations showed high technical efficiency. The smut infection was liquidated completely. Development of root rot at the phase of bushing out in barley was decreased by 28 – 40 %. The seed mordants promoted the preservation of plants up to harvest. Due to seed mordants a reliable increase in the number of barley plants surviving up to harvest of average 12 – 18 % was observed both in damp and in rather droughty years.The greatest reliable increasedue to the use of the preparations was observed in rather droughty year. In the total of two years the saved crop averaged 5,1 – 7,3 c/hectare, or 19 – 28 %. The use of system fungicides – seed mordants is required for the formation of barley agrocenosis, preserving shoots from smut infections, protection against root gels, increasing in plants survival up to harvest. At the forecast of shoot wreckersactivity it is expedient to include system insecticides in structure of mordants.
