THE EFFECT OF PRE-WARMING, PRE-SOAKING AND HOT-WATER TREATMENT ON THE GROWTH OF NARCISSUS AND CONTROL OF STEM EELWORM (DITYLENCHUS DIPSACI(KÜHN) FILIPJEV)

Experiments with both infested and healthy narcissus bulbs show that warm storage (7 days at 30°C or 5 days at 35°C) immediately before hot-water treatment reduces all forms of crop damage but necessitates the use of pre-soaking and a higher HWT temperature to maintain eelworm control.
Pre-soaking for 3 hours or 24 hours were equally effective.
The use of formaldehyde in HWT was vital for efficient eelworm control with pre-warmed bulbs.
