Other claims from this paper (10)
- Intervention effect Stalk population became equivalent among treatments by 52 weeks.
- Observation The height response to 2,4-D varied between years.
- Intervention effect In 2001 at 52 weeks, 2,4-D at one, three or five weeks before planting reduced height.
- Intervention effect In 2001, residual 2,4-D reduced sugarcane yield at least 11%.
- Intervention effect In 2001, residual 2,4-D reduced sugar yield at least 12%.
- Intervention effect The untreated control and seven-week 2,4-D treatment had equivalent yields in 2001.
- Intervention effect 2,4-D application did not negatively affect yield in 2002.
- Intervention effect Billet planting consistently increased shoot populations across seasons.
- Intervention effect Billets yielded 18% more than whole stalks in the first year.
- Recommendation The authors recommend seven weeks between 2,4-D application and harvest of seed cane.
