摘要

Citrus trees (Citrus sinensis) with symptoms resembling withertip on twigs and tear stain on fruits were observed in Morocco. Lime (Citrus aurantiifolia) was not affected. The dieback often progressed slowly and caused leaves to wilt, turn yellow and drop off. Twigs and branches appeared to have been scorched by fire. When twigs were dry, minute brown-to-black, slightly raised, clumped pustules were observeded. Under humid conditions, a pink slimy material appeared on dead bark and twigs. This symptom has also been observed on seedlings of citrus rootstocks in glasshouses in Morocco Affected fruit showed tear stain symptoms, as described by Fawcett (1936). The symptoms were superficial on the unbroken peel and formed dull red to dull reddish-green streaks or bands down the fruit. In some cases, these covered a large percentage of the fruit surface. On late-season, overripe fruit, the streaks sometimes became brownish in colour, resembling rust mite damage.
