    Fuchsia rust *
    (Pucciniastrum epilobii)
    Initially, small brown areas appear on underside of leaves. Later, large circular areas of chlorosis occur and yellow-orange uredospores appear on the underside of leaves. Older leaves may have green tissue around infected areas. Eventually uredospores appear on both sides of leaf. Infected leaves usually drop. Overwinters as teliospores on fireweed or as basidiospores on fir. Uredospores 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.
    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 root and crown rots * (Phytophthora spp.), various viruses * (Tomato spotted wilt virus), eriophyid mites, and root knot nematodes** (Meloidogyne hapla).
