Ecological and economic effectiveness of measures of invasive species-introductors control

Abstract

The results of many years of research on the monitoring of invasive species-introducers and tested measures for their control are presented. It has been established that in the one-year-old colonies, the use of mechanical cutting or one-time use of the recommended herbicides is effective. When mechanical cutting of localized locations of root-epidemic introduces for the complete eradication of species during the growing season, it is advisable to carry out three-, four-time mowing of the above-ground mass. On small areas of land, the digestion of rhizomes is effective. In colonies of perennials, the one-time application of herbicide with a minimum rate of expenditure on colonies of perennials, in particular oxybafus of a flower, promotes the suppression of growth and development of plants, which manifests itself in the formation of generative shoots. To eradicate the colonies completely, it is necessary to re-treat or increase the rate of herbicide consumption. It is expedient to use the complex of measures - biological, chemical and agrotechnical to control the spread of root and plant plants. Among the ecologically effective and economically feasible proven control measures, in particular for the Syriac wafer, it is necessary to distinguish the treatment of plants during vegetation with a mixture of herbs Titus and Mushket — the costs for this measure of control are 370 UAH / ha, which is cheaper than the threefold mowing of the above-ground part by 4. 6 times. The first treatment with a tank mixture of the locality of invasive species-introducers should be carried out in the formation phase of 2–7 pairs of leaves. After repeated plant regeneration, it is necessary to repeat the treatment without using mechanical means of soil cultivation in order not to stimulate the development of new shoots from crushed or damaged rhizomes.
