Disease Control Outlines
In this Guideline:
|Disease (causal agent)
||Survival of pathogen and effect of environment
||Comments on control
||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 *
