Title: The effect of Phyllanthus virgatus extract on common weed species

An aqueous extract of P. virgatus (leaf/stem/fruit), was mixed with agar to produce a 5% FW/v substrate concentration. Seeds of Apium leptophyllum, Avena fatua, Bidens pilosa, Chenopodium album, Echinochloa crus-galli, Lolium rigidium, Parthenium hysterophorus, Raphanus raphanistrum, Sonchus oleraceous and Urochloa pannicoides were placed on the agar and germinated under controlled conditions for 7-16 days. The extract caused a significant reduction in the germination of A. leptophyllum, L. rigidium, P. hysterophorus and S. Oleraceous from 100% down to 63.2%, 88.0%, 49.4% and 40.8%, respectively. Shoot growth was significantly reduced by 8.1% to 65.8% in most weed species. Root growth was so severely affected in all species that the survival of seedlings would be unlikely if the extract environment was maintained.Read More
