Mogućnosti suzbijanja bagremca (Amorpha fruticosa L) primenom herbicida glifosat i sulfosat

Abstract

Bagremac (Amorpha fruticosa L) je najznačajnija korovska vrsta u zasadima topola na lokalitetu Palanačke Ade (Čipski Poloj). Pored bagremca, prisutne su i druge drvenaste vrste: Vitis vinifera Gmel., Cornus sanguinea L.,Acer negundo L.,Robinia pseudoacacia L.,Ailanthus glandulosa Desf. i Rubus sp. U suzbijanju bagremca korišćeni su vodeni rastvori herbicida Roundup (glifosat) i Touch-down 4LC (sulfosat), u koncentracijama 0.5,1,2 i 5%. Tretiranja su vršena krajem juna 2000. i 2001. godine. Oba herbicida efikasno su delovali na bagremac u koncentraciji 1%. Ostale drvenaste vrste ispoljile su veću otpornost na herbicide od bagremca.

False indigo (Amorpha fruticosa L) is the most important weed species in poplar plantings in the locality of Palanačke Ade (Čipski Poloj). Apart from the false indigo, there are other woody species: Vitis vinifera Gmel, Cornus sanguinea L., Acer negundo L, Robinia pseudoacacia L., Ailanthus glandulosa Desf. and Rubus sp. Herbicides Roundup (glyphosate) and Touch-down 4LC (sulphosate) there were used in the concentration of 0.5,1,2 and 5% in false indigo control. The treatments were carried out at the end of June 2000/2001. Both herbicides were efficient in false indigo control in the concentration of 1%. Other species proved to be more resistant to these herbicides.
