*2.7. Cluster Analysis for the Screening of Biological Weed Control Agents*

Cluster analysis was carried out for the grouping of strains applied in antimetabolite assays on weeds and wheat. The strains were categorized as non-selective biological weed control agents (the strains that reduced the growth of all the tested weeds and wheat), selective (the strains that reduced the growth of some of the tested plants and also wheat), selective (the strains that reduced the growth of some of the weeds but not wheat), and selective (the strains that reduced the growth of one more weed but promoted the growth of wheat). Five most efficient strains of allelopathic bacteria obtained from this study were identified through 16s rDNA sequencing as *Pseudomonas* strain T42 as *Pseudomonas putida*, strains L9 and 7O0 as *P. fluorescens*, strain O010 as *P. aeruginosa*, and strain W9 as *P. alcaligenes*.
