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).
