- Intervention effect Under elevated CO2, rice vegetative tillers increased by 18% relative to ambient CO2.
- Intervention effect Under elevated CO2, rice reproductive tillers increased by 22.1% relative to ambient CO2.
- Intervention effect Under elevated CO2, rice 1000-seed weight decreased by 11.2% relative to ambient CO2.
- Intervention effect Under elevated CO2, rice grain yield decreased by 18.8% relative to ambient CO2.
- Intervention effect 700 l/ha spray gave higher BPH mortality at ambient than elevated CO2.
- Intervention effect 600 l/ha spray gave higher BPH mortality at ambient than elevated CO2.
- Intervention effect 500 l/ha spray gave higher BPH mortality at ambient than elevated CO2.
- Intervention effect 400 l/ha spray gave higher BPH mortality at ambient than elevated CO2.
- Observation BPH population was higher in 2017 than in 2018.
- Mechanism Higher canopy size under elevated CO2 could explain lower efficacy of 500 l/ha spray against BPH.
- Recommendation The authors recommend revising spray volumes for effective BPH management under climate change.
