The Efficiency of Applying New Anti-Weed Technologies in the Irrigation Canals and Collector-Drainage Systems of the Ararat Valley

Abstract

In 2018-2020 a new technology against the harmful flora of the lower Hrazdan and Artashat irrigation canals and collector-drainage systems at the Ararat valley was explored, scientifically justified and recommended for implementation. Physiologically active anti-weed preparations have been applied. In the irrigation systems, where cane is also widespread, Arsenal New and Uragan Forte have been used, while in the over-moistened collector-drainages Uragan Forte and in the cane-free areas Epic (Sado) and Anchor 85 have been used. In the result of new technology application the irrigation water losses are reduced and the proliferation of weeds and field dodder towards the land user’s fields is prevented.
