Rusts on trees

Thanks for your e-mail.

For rusts on trees you really need some fungicides, which Harrod currently do not sell but are looking at natural ones for next year. In the mean time I suggest you spray with something like Difenoconazole [ Westland Plant rescue fungus control ] or Triticonazole [ Scotts Fungus clear extra] or their professional equivalents. In the autumn burn any fallen leaves or remove to take away infection points.

Hope this helps.
