Weed control in 1999 and comments for 2000.

Abstract

In 1999, the main weeds to cause problems in sugarbeet in the UK were Fallopia convolvulus (black bind-weed) and Chenopodium album (fat-hen). C. album caused yield losses of 20% where the weed had emerged early and was not adequately controlled. Advice is given for the chemical control of F. convolvulus, C. album, volunteer potatoes, Avena fatua (wild oats), Poa annua (meadow grass), volunteer cereals, Alopecurus myosuroides (black-grass) and Elymus repens (common couch) in the 2000 season. A list of new herbicide registrations for 2000 is provided.
