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.
