The effectiveness of the use of herbicides for silvicultural care of forest plantations in the green area of Astana
The efficiency of various doses of geicoll, fenisane, raund up and fusilad combating weedy grasy vegetation in rows of ferest
culture such as ash leaved maple, elm poplar and willow growing in Astana green zone has been determined. It was envisaged
to study the effect of different doses of four types of herbicides on weed grass vegetation in order to establish the possibility
of their use in the expression green space in the buffer zone of the city of Astana. High efficiency of herbicides application
and dependence of the latter from the ratio of perennial and annual welds, as well as the composition of forest cultures has
been experimentally proved. Chemical maintenance of forest plantations is an effective way to reduce pollution in both annual
and perennial weeds. The use of herbicides drastically reduces labor costs for weed control, and, consequently, the cost
of forest growing. The effectiveness of herbicides depends not only on their kinds and doses, but the composition of forest
crops. Thus, in particular cultures box elder comfortable performance indicators and fenizan glisol characterized in doses of 2.5
and 0.2 l/ha, respectively. In cultures elm squat against perennial weeds effectively in use Roundup dose of 4.5 l/ha, and against
annual glisol at 2.5 l/ha. In a cultures of poplar and willow effectively use Roundup and flyuzilad at doses of 3.0 and 2.0 l/ha,
respectively. Given the wide range of forest plantations in the green area of the city of Astana, as well as differences in the ratio
of annual and perennial weeds, a study on the effectiveness of herbicides for weed control should be continued.
