Comments on control |
| Fuchsia rust
(Pucciniastrum epilobii) |
Initially, small brown areas
appear on underside of leaves. Later, large circular areas of chlorosis occur
and yellow-orange urediospores appear on the underside of leaves. Older
leaves may have green tissue around infected areas. Eventually urediospores appear on both sides of leaf. Infected leaves usually drop. |
Overwinters as teliospores on fireweed or as basidiospores on fir. Urediospores on fuchsia can reinfect fuchsia. |
Remove fireweed and infected
plants. Applications of mancozeb are effective. Avoid wetting leaves. Prune
back to stems and remove cuttings. more info * |
| Fuchsias
are also susceptible to crown gall * (Agrobacterium tumefaciens), Verticillium wilt * (Verticillium dahliae),
Armillaria root rot (Armillaria mellea), damping-off * (Pythium rostratum, P. ultimum and Rhizoctonia sp.), Phytophthora * (Phytophthora spp.), various viruses * (TSWV), Eriophyid mites, and root knot nematodes** (Meloidogyne
hapla). |
