What causes clematis to die?
The most devastating problem of clematis is a fungal stem rot and leaf spot called clematis wilt. The two fungi credited with causing clematis wilt are Phoma clematidina and Ascochyta clematidina. With this disease, the plant or part of the vine suddenly collapses, and within a few days, the stem and leaves turn black and die. Cut off and destroy all the affected parts. Rake up and dispose of fallen foliage. If the clematis was planted with two buds below the ground, it will usually grow back from the base the following year. Plants in their first year of growth seem to be more susceptible than established vines. This is a disease mainly of large-flowered hybrids. Small-flowered hybrids, the species and their cultivars, are less susceptible to wilt. Therefore, try one of the lovely small-flowered species if there has been trouble with wilt in the past.
What fungicides are used to kill powdery mildew?
For fungicides to be effective in powdery mildew control, they must be applied as soon as symptoms are noticed.

Horticultural oil mixed with potassium bicarbonate can also give good powdery mildew control on ornamentals. When powdery mildew persists and sprays are repeated, it is recommended to rotate (alternate) any systemic fungicides with contact fungicides in order to decrease the chance of fungi developing resistance. Please see Table 1 for fungicides labeled for powdery mildew control on clematis.
