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) |
| Author: | A.A. Tompsett |
| Abstract:
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. | |
