Other claims from this paper (9)
- Intervention effect Daily manual silk clipping had modest effects on corn yield parameters.
- Intervention effect Sustained manual clipping three times daily affected total kernel weight during early silking.
- Intervention effect Caged Japanese beetles affected total kernel weight during early silking.
- Intervention effect Three daily clips during the first five days of silking affected kernel number, total kernel weight, and individual kernel weight.
- Intervention effect Caged beetle feeding reduced kernels per ear depending on beetle number.
- Intervention effect Eight beetles per ear significantly reduced total kernel weight relative to noninfested ears.
- Observation Pollinated kernels increased in size, partly compensating for reduced pollination.
- Observation Substantial yield and pollination effects required sustained clipping in the first silking week under good growing conditions.
- Recommendation The authors considered the stated three-beetle treatment threshold adequate.
