Home > Question >

What can I use to control blackspot on climbing roses?


Our Advice:

Independent trials have shown that Multirose Q4 or Systhane Fungus Fighter both from Bayer appear to give good control. Aim to get a protective layer over the leaves before the disease becomes established. Also, spray the supporting structure to kill any fungal spores lurking there.
