Other claims from this paper (14)
- Intervention effect Nozzle design did not influence herbicide coverage in a narrow row soybean canopy.
- Intervention effect Spray volume of 140 l ha-1 gave greater coverage in a narrow row soybean canopy than 94 l ha-1.
- Intervention effect Herbicide efficacy was influenced by nozzle design only when applied to high-density weed stands or to weeds beyond recommended height.
- Recommendation Applications of 2,4-D and dicamba with low drift nozzles can provide control of troublesome broadleaf weeds when applied after a residual herbicide to appropriately sized weeds at spray volumes above 94 l ha-1.
- Intervention effect Herbicide strategies relying on glyphosate plus dicamba or 2,4-D with minimal residual herbicide gave greater weed densities and number of weed species.
- Intervention effect The minimal-residual glyphosate plus dicamba or 2,4-D strategies indicate a significant increase in herbicide resistance selection pressure.
- Intervention effect Dicamba or 2,4-D reliant strategies resulted in shifts towards monocot species.
- Observation Fall panicum became the predominant weed species under dicamba or 2,4-D reliant strategies.
- Intervention effect Integrated strategies with soil residual herbicides reduced both dicot and monocot species abundance.
- Observation A predominant weed species was not apparent after four years under integrated strategies with soil residual herbicides.
- Recommendation Air induction nozzles will reduce the potential for off-site movement of herbicides in this soybean system.
- Intervention effect Air induction nozzles did not reduce herbicide efficacy against target weeds when used appropriately.
- Recommendation The useful life of these technologies can be lengthened by implementing herbicide strategies with multiple sites of action, soil residual herbicides and cultural weed management.
- Recommendation Longevity of the 2,4-D resistant and dicamba resistant soybean systems depends on implementation of best management practices.
