Lepidium Organism

Cress (Lepidium sativum) and radish (Raphanus sativus) are small seeds, quick to germinate and sensitive to phytotoxic (plant damaging) substances like the organic acids temporarily present in immature composts.

Strychnine inhibits growth of the radicle of Lepidium and is toxic to Lemna (Wink, 1993). Strychnine (45) and brucine (46) are feeding deterrents to polyphagous Syntomis, Pieris, and Bombyx larvae (Lepidoptera) and a variety of other organisms. Both alkaloids are insecticidal to bees (Wink, 1993).
