The Current State of Weediness in the Hrazdan᾿s Lower and Artashat Irrigation Systems

Abstract

According to the study results conducted in 2018-2019, it was found out that the banks of Hrazdan᾿s Lower and Artashat irrigation systems are heavily littered with monocotyledonous and dicotyledonous weeds (64 species). Stem dodder (Cuscuta), parasitized on the weeds and shrubs, is also very common. Weed seeds, accumulated at the base of irrigation nets during the period of water supply termination, are transferred to the land areas of the Ararat valley during irrigation and new foci of weeds appear.Thus, the development and implementation of new anti-weed technologies are primary tasks for the solution of the aforementioned issues.
