- Title
FURTHER EXPERIMENTS ON THE CONTROL OF BULB FLY IN NARCISSUS.

- Abstract
This article looks at experiments conducted on methods for controlling bulb fly. In spite of the variation between results it seems clear that a strength below 0.2 per cent (actual chemical) does not give satisfactory control of damage. Therefore, for all advisory work it has been decided to retain the recommendation of a dip of fifteen minutes in 0.2 per cent aldrin. Work in the U.S. and in Canada had shown that the application of insecticides to the soil immediately below the bulb had been successful in stopping attack by the bulb fly. Because of the damage caused by treating too late in the season, these methods were tried out in Cornwall. Work was started in 1957, but the summer of 1958 was so bad that the bulb fly attack was light and patchy, and some results on bulbs lifted in July 1958, were inconclusive. No phytotoxic damage was seen during the growing season. Flower picks showed little variation between treatments.
