Recognising the increasing difficulty in effective fallow control of sowthistle and grasses and the potential role of residual herbicides, a series of field trials were established to compare efficacy of residual herbicide treatments across a range of environments and soil types.
Key messages
1. Terbyne® Xtreme® and Valor® provided the best residual control of common sowthistle as stand-alone residual herbicides and as mix partners with ‘grass active’ herbicides.
2. Group K, Group D and Flame® provided the best residual control of grass weeds as standalone residual herbicides and as mix partners.
3. Herbicide mixtures provided improved control over individual products and are likely to provide more wide-spectrum control of a range of weed species.
