Quassia Amara Extrakt und Rinde

From the Wood of the Quassia Plant

Quassia-Extract-MD contains quassine, the pure active substance from the wood of the quasia plant or the bitter wood tree. The active ingredient is obtained as a powdery plant extract in a specially developed process.

  • Areas of Application
  • Mode of Action

Quassia-Extract-MD is used against sawflies (Hoplocampa spp.) in pome and stone fruit in the field.

Quassia-Extract-MD contains the active substance quassine, which permeates into the leaves and is distributed partially systemic in the plant. It is ingested by pest organisms via suckig or feeding. Quassia-Extract-MD has no immediate toxic effect (no “knock down”) and has a special multi-stage mode of action. Within a few hours after the application it has an inactivating effect on specific pest insects. They cease their food uptake and thereby their plant-damaging activities. The developmental and moulting processes of the pest organisms are inhibited, which leads to mortality after a few days.
