In Germany pea moth (Cydia nigricana, Lep.: Tortricidae) is a serious problem especially for organic vegetable peas. CpGV is a natural virus for Cydia pomonella. The virus does not act by contact, only by ingestion. Small scale field-tests with CpGV were conducted according to EPPO-guidelines (EPPO 2000) with grain pea cv. ‘Santana’ in a randomised block design in 4 replicates. At the time of egg hatching peas were sprayed with CpGV. Efficacy assessments were based on the percentage of damaged peas, the numbers of larvae per pod, larval stage and yield loss. 2004 an UV-protection powder was tried unsuccessfully. Also a very high concentration did not cause a significant reduction of larvae in the pods.
