	IMPROVING WEED CONTROL DECISIONS Improving the accuracy of decision making is a major constraint in optimising weed control strategy and herbicide use. This provides a focus for several current developments and an advanced system is the Danish decision support system. Mr Per Kudsk (Danish Institute of Plant Sciences, Flakkbjerg, Denmark) will outline the development of this computerised system and its implementation. Papers will focus on techniques to improve decision making in weed control; from computer based through to much simpler systems. Components of weed control which might ultimately lead to a more advanced system will be reviewed. Chairman and Session Organiser: Mr J Clarke (ADAS, Boxworth, UK) Back

	HERBICIDE RESISTANT WEEDS: WHAT'S NEW? The number of herbicide resistant weeds continues to increase and over 200 resistant biotypes have been found in 45 countries world-wide. An increasing number of these cases are in developing countries where herbicides are starting to be used more intensively. New or topical information about the evolution, mechanisms, genetics and management of resistant weeds will be presented. Dr Ian Heap (Consultant, Corvallis, USA) will provide an overview based on his experiences of establishing and maintaining the International Survey of Herbicide Resistant Weeds. This session complements Poster Session 3C. Chairman: Dr J Caseley (IACR-Long Ashton, Bristol, UK) Session Organiser: Dr S Moss (IACR-Rothamsted, Harpenden, UK) Back

	EVENING DISCUSSION
	WEED RESISTANCE ACTION GROUP [WRAG] This will be an open meeting of the UK Weed Resistance Action Group (WRAG). WRAG members, and all other interested delegates, are invited to attend and participate. The meeting will briefly review WRAG activities including: the status of resistance in the UK and the rest of Europe; the new HGCA resistance topic sheet; the new system for designating degree of resistance in screening assays; workshops on the risk of resistance in broad-leaved weeds; discussions on resistance warnings and the merits of including mode of action information on herbicide labels; baseline monitoring/background sensitivity; resistance websites; liaison with other Resistance Action Groups and the Herbicide Resistance Action Committee (HRAC). Chairman: Mr J H Orson WRAG Chairman, c/o Morley Research Centre, Wymondham, UK Session Organiser: Dr S R Moss WRAG Secretary, c/o IACR-Rothamsted, Harpenden, UK Back
