Other claims from this paper (17)
- Intervention effect Clopyralid at a maximum rate of 90 g/ha did not adversely affect vegetable yields.
- Intervention effect Clopyralid at 45 g/ha mixed with picloram at 30 g/ha did not adversely affect vegetable yields.
- Intervention effect Spraying 60 g/ha clopyralid controlled burr medic.
- Intervention effect Spraying 60 g/ha clopyralid suppressed common sowthistle.
- Intervention effect Applying 90 g clopyralid/ha controlled both burr medic and common sowthistle.
- Intervention effect Mixing 22.5 g clopyralid/ha with 15 g picloram/ha controlled both burr medic and common sowthistle.
- Intervention effect At the rates tested, clopyralid did not affect deadnettle.
- Intervention effect At the rates tested, picloram did not affect deadnettle.
- Intervention effect Applying 450 g pyridate/ha caused chlorotic spotting of the sprayed vegetable leaves.
- Intervention effect Applying 450 g pyridate/ha did not affect marketable yields of broccoli, cabbage or cauliflower.
- Intervention effect Pyridate at 450 g/ha controlled deadnettle.
- Intervention effect Pyridate at 450 g/ha reduced sowthistle growth by only 30-50% compared with an unweeded control.
- Intervention effect Spraying 900 g pyridate/ha increased the severity and persistence of chlorotic spotting.
- Intervention effect Spraying 900 g pyridate/ha resulted in lower broccoli and Chinese cabbage yields than in the best treatments of the respective experiments.
- Intervention effect Cabbage and cauliflower yields were unaffected by spraying 900 g pyridate/ha.
- Intervention effect Pyridate at 900 g/ha improved sowthistle control to a commercially acceptable level.
- Recommendation The authors suggest that clopyralid and pyridate could be successfully used in Australian vegetable brassica production, once residual activity of clopyralid on following crops and optimal pyridate rates and timing are resolved.
