Other claims from this paper (13)
- Observation The hand-weeded control had the highest bee visitation, averaging 6.11 visits per head per ten minutes.
- Intervention effect Eclipse plus Filder reduced bee visitation by 56%.
- Intervention effect Challenge reduced bee visitation by 33%.
- Intervention effect Helianthex reduced bee visitation by 82%.
- Association Bee visitation in 2024 was 1.28 versus about 4.5–5.0 in 2022–2023.
- Intervention effect Eclipse plus Filder reduced yield by 0.31 t/ha or 8%.
- Intervention effect Primextra TZ Gold plus Yastryb reduced yield by 0.35 t/ha or 9%.
- Intervention effect Stels reduced yield by 0.58 t/ha or 15%.
- Intervention effect Challenge reduced yield by 0.76 t/ha or 20%.
- Intervention effect Helianthex reduced yield by 27%.
- Association Soil-applied programmes had lower risk to pollinator activity and yield than post-emergence chemistries.
- Association Drought strongly limited pollinator activity and yield.
- Recommendation Pollinator-sensitive herbicide selection with seasonal risk management may sustain pollination services and productivity.
