I wanted to ask about viral pesticides. Do those fall under your purview as well? There was an attempt a few years ago to use baculovirus, a virus found in insect gut and also found in human liver and kidney cells. There was some concern because they were going to load it with a scorpion venom gene. It wasn't approved, thank goodness. Are there other examples of viruses being used as pesticides that have been approved in Canada?
