Canada to approve Cydia pomonella granulovirus isolate V-22 and Madex HP

Health Canada's Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act, is proposing registration for the sale and use of CpGV V-22 Technical and Madex HP, containing the technical grade active ingredient Cydia pomonella granulovirus isolate V-22, to control codling moth (Cydia pomonella) and oriental fruit moth (Grapholita molesta) on stone fruits (Crop Group 12-09) and pome fruits (Crop Group 11-09).

An evaluation of available scientific information found that, under the approved conditions of use, the health and environmental risks and the value of the pest control products are acceptable.

Cydia pomonella granulovirus isolate V-22 is an insecticidal virus. Virus particles must be ingested by larvae to infect them. During infection, the virus replicates and disrupts feeding, resulting in death. After death, the larvae disintegrate, spreading additional virus particles where nearby larvae may become infected.

Madex HP is a new non-conventional commercial class product that controls codling moth and oriental fruit moth on stone fruits and pome fruits. It can be used by organic growers and in integrated pest management programs.

Applications of Madex HP target early larval stages of codling moth and oriental fruit moth. Cydia pomonella granulovirus isolate V-22 represents a new non-conventional product containing a new virus isolate for use on food crops, which will contribute to resistance management.

Before making a final registration decision on Cydia pomonella granulovirus isolate V-22 and Madex HP, Health Canada's PMRA will consider any comments received from the public. Health Canada will accept written comments on this proposal before 13 September 2021.
