Summary

The pea moth Cydia nigricana Fabricius (Lepidoptera: Tortricidae) has developed to an important pest in pea growing areas (green and grain peas) causing high economic damage. Currently no effective pest control options are available under organic farming conditions. The presented project aims to generate a first draft of pea moth control in organic farming including a risk assessment of pea moth damage incidence and a direct control approach.
Data collection for risk evaluation were arranged for three years (2006 – 2008) in two exemplary pea growing areas in Germany (North Hessen and Central Sachsen). In a small plot experiment in Northern Hessen the combined effect of a pyrethroid product (Spruzit-Neu®, W. Neudorff GmbH KG, Emmerthal, Germany) and different sowing dates using three common green pea cultivars (Avola, Deltafon, Ambassador) on C. nigricana were investigated.
In 2006, the coincidence avoidance of flowering pea plants and flight activity of C. nigricana via alternative sowing dates resulted in reduced pea moth infestation. The pyrethroid showed significant pea moth reduction using early sowing dates (Avola, Deltafon). However, the results have to be confirmed in continuative experiments in 2007 and 2008.
