Abstract

Abstract
The aim of this study was the identify cyanobacterial flora of rice–fields in Dargaz, to interaction between cyanobacteria by culturing in solid medium BG-110 in laboratory was investigated. Nostoc piscinale and Nostoc spongiaeforme were identified as strongest and weakness species, respectively, regarding secondary metabolits producing (allelochemicals).The algal pairs were classified in two groups based on their interactions. Possibility of using blue-green algae allelochemicals to combat harmful algae blooms (HABs) and agriculture science was discussed.
