Hold the Bayer (advanced desaese control). I had that and Ortho Daconil mixed up. I use Bayer Desease Control as a systemic preventive for black spot, powdery mildew, rust, etc. It's Daconil that I use specifically for leaf curl. Right now I've got Ortho but I've used others--as long as they contain Daconil. Thanks for noting that, Rick.
