Disease symptoms caused by Botrytis cinerea in Ruscus hypoglossum plants and their control.

In field trials in Israel, infection of R. hypoglossum by B. cinerea resulted in small spots on the young phylloclades. The dark, watersoaked spots with a faint halo later became brown but did not grow in size. Significant disease reduction (>90%) was obtained by sprays of fenbuconazole, vinclozolin alone or combined with copper, TMTD [thiram], diethofencarb + carbendazim or with Nufilm. Polyoxin D reduced disease incidence by 68 and 85% when applied at 0.045 and 0.09 g/litre, respectively, and disease development was delayed by copper sulfate, pentahydrate and by Nufilm at a high rate of application. Postharvest control of grey mould (up to 72% reduction) in mature branches stored at 18 deg C was achieved by application of vinclozolin, iprodione, diethofencarb + carbendazim, dichlofluanid, fenbuconazole, tebuconazole, tebuconazole + dichlofluanid, polyoxins and vinclozolin + thiram. Measures designed to improve field control of Botrytis epidemics in Ruscus are discussed.
