WG as Invited speaker

The WG co-ordinator was an invited speaker at the following international Symposia:

• 8th ISHS Symposium on Processing Tomato, Istanbul, Turkey, 8-10 June 2002

• 5th International Weed Science Congress, Vancouver, Canada, June 2008

Future activities• improving, updating and managing the WG website

• supplementing information and results on weeds and weed control strategies in vegetables (onions, processing tomato, carrots, peas, cabbages, lettuce…..)

• Increasing the WG members

• Stimulating the participation in this field of research

• Manuals on weed control strategies in vegetables with information on:

Weeds: damage, dispersal,……

Prevention: preventive measures, rotations, false seedbed,..

Decision making: threshold weed densities, critical periods of weed competition…….

Direct control methods: chemical, physical, …….
