We tried a mix of three copper based fungicides on severe southern rust (at different stages) last year and zero BPA gain with repeated side by sides weighed.
We tried Romeo, Pacesetter and Badge, all mixed together as recommended.
Copper as a fungicide should only used as a preventative, not a curative. Also copper can affect your naturally good biology as well. If you didn't apply it before the rust, it might have been too late |
Organic Fungicide?
