The effect of pre-warming, pre-soaking and hot-water treatment on the growth of narcissus and control of stem eelworm (Ditylenchus dipsaci (Kuhn) Filipjev)


, : The effect of pre-warming, pre-soaking and hot-water treatment on the growth of narcissus and control of stem eelworm (Ditylenchus dipsaci (Kuhn) Filipjev). Acta Horticulturae (47): 165-170

Experiments with both infested and healthy narcissus bulbs have shown that warm storage (7 days at 30 deg C or 5 days at 35 deg C) immediately before hot-water treatment reduces all forms of crop damage but necessitates the use of pre-soaking and a higher hot-water temperature to maintain Ditylenchus dipsaci control. Pre-soaking for 3 hours or 24 hours were equally effective.

An examination of a consignment of English bulbs supported the theory that the spread of infection of bulb eelworm from scale to scale takes place by way of the basal plate, and that the infected scales turn brown.

A similar treatment on tulips did not control the nematode. There was no evidence that thion...
