The aim of the study was to assess the allelopathic potential of three local species of Paronychia (P. argentea, P. kurdica, P. splendens) against weeds while maintaining crop tolerance. Laboratory biotesting revealed high selective phytotoxicity: 10% extract of P. argentea from Sharur completely inhibited the germination of common pigweed, while reducing wheat germination by only 11.4 ±2.5%. Extracts from arid regions (Sharur, Shahbuz) exceeded the activity of analogues from Ordubad and Kangarli by 20-25% (p < 0.01), especially against field bindweed and barnyardgrass. Species specificity confirmed the advantage of P. argentea, while P. splendens was most effective against amaranth. Increasing the concentration (from 1% to 10%) enhanced weed inhibition by 40-65%, causing root necrosis (-92%) and shoot deformation. The study’s results provide a strong foundation for the development of P. argentea-based bioherbicides, particularly from Sharur populations, as a regionally adapted and ecologically sustainable alternative to synthetic herbicides. Its core advantage – selectivity, manifested in the suppression of weeds without compromising crop growth – makes P. argentea a promising model species for environmentally responsible weed control and the restoration of degraded soils in arid agricultural landscapes.
