INFORMATION not included on herbicide labels or readily available elsewhere will be a key inclusion in a new Weed Management Support System being planned for winter wheat growers and their advisers.
The idea behind the £2m four-year project is to help users plan and develop weed management strategies better across the whole rotation, bearing in mind cropping and cultivation sequences, explains project co-ordinator James Clarke of ADAS.
Long term effects
Unlike fungicide use, which tends to be season-specific, herbicides have long term financial and environmental effects which need to be considered, he says. "Weeds are not one-year wonders."
Other players in the DEFRA-sponsored project include HGCA, IACR-Rothamsted, SAC, Silsoe Research Institute and several agrochemical manufacturers. *
