Science into practice - what does the future hold for slug control?

Slugs are a source of persistent economic damage to horticultural crops. They cause direct damage to crops such as Brussels sprouts and lettuce by grazing the wrapper leaves and lower petioles.

Contamination can also be a problem in leafy brassicas and lettuce when slugs, particularly the grey field slug Deroceras reticulatum, hide in the foliage at harvest.

Such damage continues to occur, despite the use of available control methods. The purpose of FV 379 was to examine current trends in the usage of molluscicides on salad crops and brassicas in the UK, review recent research and assess current control measures and those that may be available in the near future.

The final report, available from the HDC site, advises growers to review their current slug control methods in the light of restrictions on the use of pelleted baits. It is recommended that the industry watches for and supports the development of new methods of slug control as and when the opportunity arises.
