Rapid weed survey at the field scale

Rapid weed survey at the field scale

Description: This protocol is based on a 2-way field crossing with 8 sequences to estimate weed abundances (4 sequences during the first crossing, 4 sequences during the way back). Qualitative scales are used to assess abundance and phenological stages.

Use: This protocol is used for pluriannual longitudinal surveys of weed infestation in commercial fields managed with innovative cropping systems with low herbicide inputs. These fields belong to farm networks devoted to demonstration and participative research.
