The active ingredient of Cyd-X™ is CpGV, Cydia pomonella granulosus virus and is based on a strain or isolate of CpGV. Certis Europe is a member of the CpGV EU task-force which has the objective of supporting and maintaining EU Annex I listing of CpGV as an active substance.
Certis commercializes CpGV across Europe as a suspension concentrate under the brand name Cyd-X. This active substance is a selective insecticidal baculovirus infecting larvae of codling moth. Granuloviruses are ds-DNA viruses consisting of enveloped, rod-shaped nucleacapsids. Cyd-X is highly specific and, apart from codling moth, few other species can be infected by this virus. Those that are infected also belong to the family of tortricid moths, but are not found in pome fruit cultivation.
Cydia pomonella granulovirus was discovered in 1964 in larvae of codling moth in apple and pear trees in Mexico. It was found to be highly virulent in the codling moth and highly selective.
It offers orchard growers opportunities to reduce their pesticide inputs when targeting codling moth control. When using Cyd-X, non-target organisms will be safeguarded and no residues in the fruit will occur. Across Europe, organic producers are dependent on CpGV-based products including Cyd-X for effective control of codling moth. Other growers integrate Cyd-X within a spray programme so that reduced pesticide programmes can be adopted in the orchard.
