Poor germination with Immunox?

Here’s a question for everyone…have you heard any rumors that spraying with Immunox causes poor germination?

I have been using Immunox for the past 3 years, and germination has been really poor all three years (between 5 and 17%), even when I’ve planted the seeds right out of the hips and allowed the flats to have extensive ripening and stratification periods. The Immunox does a pretty good job on blackspot and mildew, and is not as dangerous as some other fungicides, but I would like to get more seedlings from my pollinations.

Has anyone else had a similar experience?
