| Post subject: | Rowan problem |
There have been a number of posts this year re bugs/infections etc. I have got another one. This is a leaf removed from a rowan seedling I have been growing for three years. The little white dots were present as the leaf unfurled this spring. I have no idea what it is but I took the precaution of removing the affected leaves then spraying with Provado. If it continues I intend to use a fungiside. Any other suggestions folks? Tony |

Tony, I did find this extract ----- Powdery Mildew Powdery mildew infects the rowan's foliage, stems and fruit. The developing shoots and flowers can also be affected. The spores of powdery mildew develop across the surfaces of the leaves, forming a covering of white fungal mildew. The leaves develop small, necrotic spots underneath the mildew that cause the rowan's foliage to distort, wilt and, at times, fall from the tree. The rowan's blooms may also become distorted or stunted. Powdery mildew infections can be controlled and prevented with pruning and fungicidal treatments. It was on this site about http://www.ehow.com/info_8342376_rowan- ... eases.html about diseases on rowens???? |
