- Intervention effect Dicamba residue caused injury and reduced dry weight and yield in sunflower.
- Intervention effect Chlorsulfuron residue caused injury and reduced dry weight and yield in mustard.
- Intervention effect Clopyralid residue caused injury and reduced dry weight and yield in lentil.
- Intervention effect Grass weed herbicides enhanced crop injury from the broadleaf herbicides.
- Intervention effect Mixing clopyralid with grass herbicides increased lentil yield loss.
- Observation Mixing chlorsulfuron with grass herbicides did not increase mustard yield loss.
- Intervention effect Diclofop increased dry weight reductions and injury more than sethoxydim in mixtures.
- Intervention effect Diclofop reduced yield more than sethoxydim in mixtures.
- Method / resource Crop tolerance ratings distinguished treatments and rates but poorly estimated yield loss.
- Intervention effect Sprayer residues caused sunflower yield loss of up to 40% versus untreated check.
- Intervention effect Sprayer residues caused mustard yield loss of up to 70% versus untreated check.
- Intervention effect Sprayer residues caused lentil yield loss of up to 95% versus untreated check.
