Papyracillic acid, a fungal metabolite, a Penicillic acid analog, is a nonselective herbicide. Papyracillic acid has anti-bacterial, anti-fungal, nematicidal, and phytotoxic effects^[1] .

Papyracillic acid at the concentration of 1 mg/mL is phytotoxic both for the host plant and a number of nonhost plants of the fungus. Papyracillic acid is active against bacteria (Xanthomonas campestris and Bacillus subtilis) and the fungus Candida tropicalis at 6 μg/disk^[1] .
