    Product Description

    Pyrenophorin is a fungal metabolite that has been found in D. avenae and has phytotoxic activity.1 It inhibits seed germination and reduces root growth of the graminaceous plants A. sterilis, A. fatua, A. sativa, T. aestivum, and H. vulgare when used at a concentration of 60 µM. Pyrenophorin (320 µM) reduces chlorophyll levels in leaf sections from seedlings of the same plants.

    WARNING This product is not for human or veterinary use.
