The effects of triclopyr and 3,6-dichloropicolinic acid on gorse

, : The effects of triclopyr and 3,6-dichloropicolinic acid on gorse. Proceedings of the Western Society of Weed Science (Vol. 42): 167-171

The efficacies of triclopyr and clopyralid against Ulex europaeus in early bloom using broadcast and directed spray application methods were compared in trials in California. Broadcast applications were tested with 1.5% v/v crop oil concentrate. Triclopyr at 1.12 kg/ha or more gave more than 90-100% control 8 weeks after treatment and this was maintained for 6 months. Clopyralid gave only 37.5% control 8 weeks after treatment with the top rate used, and no improvement was observed at 6 months.
