Other claims from this paper (10)
- Observation Common ragweed was the most difficult weed to control and its control appeared to most affect peanut yield.
- Intervention effect Preplant-incorporated treatments gave no common ragweed control.
- Intervention effect Ethalfuralin plus vernolate PPI controlled yellow nutsedge by better than 90%.
- Intervention effect Ethalfuralin plus vernolate PPI controlled morningglory by nearly 50%.
- Intervention effect Single paraquat after PPI gave less than 75% common ragweed control.
- Intervention effect Ethalfuralin plus vernolate PPI followed by paraquat at one week yielded 4400 kg ha −1, equivalent to handweeding at 4470 kg ha −1.
- Intervention effect Ethalfuralin plus vernolate PPI followed by sequential paraquat yielded 3730 kg ha −1, not significantly below handweeding.
- Intervention effect Ethalfuralin plus vernolate PPI followed by acifluorfen plus bentazon yielded 3730 kg ha −1, not significantly below handweeding.
- Intervention effect Ethalfuralin PPI followed by sequential paraquat yielded 3740 kg ha −1, not significantly below handweeding.
- Intervention effect Ethalfuralin plus vernolate PPI and paraquat at one week had the highest net return of $1370 ha −1.
