Other claims from this paper (10)
- Intervention effect Diclofop-methyl alone did not decrease leaf extension in either Avena species until at least four days after spraying.
- Intervention effect Diclofop-methyl alone did not decrease leaf extension of A. fatua until at least four days after spraying.
- Intervention effect All broadleaf herbicides combined with diclofop-methyl decreased leaf extension of both Avena species within two days.
- Intervention effect Combined broadleaf herbicides and diclofop-methyl reduced leaf extension of A. fatua within two days.
- Intervention effect After ten days, all combinations yielded lower leaf extension than unsprayed plants but higher than diclofop-methyl alone.
- Intervention effect Long-term growth after combined herbicides was generally below unsprayed plants but above diclofop-methyl alone, except for A. fatua with bentazone.
- Intervention effect Bentazone with diclofop-methyl substantially reduced A. fatua leaf extension within 24 hours.
- Intervention effect Bentazone at 0.3 kg a.i. ha −1 with diclofop-methyl reduced A. fatua leaf extension within one day.
- Intervention effect At the lower bentazone rate, A. fatua harvest dry weight lay between unsprayed plants and diclofop-methyl alone.
- Mechanism The authors propose that early reduced leaf expansion causes broadleaf herbicide antagonism of diclofop-methyl.
