Synthetic Auxin Herbicides Control Germinating Scotch Broom

Synthetic Auxin Herbicides Control Germinating Scotch Broom

A variety of fire, herbicide, and mechanical treatments are effective for controlling established Scotch broom. However, observations regarding effectiveness of soil-active herbicides in controlling germinating seedlings of Scotch broom are limited. Researchers conducted a series of studies in growth chambers beginning in 2010 to compare the effectiveness of three soil-active auxin herbicides: aminopyralid (Milestone® specialty herbicide), clopyralid (Transline® specialty herbicide) and aminocyclopyrachlor for controlling Scotch broom seedling germination.

Logging Debris and Herbicide Treatments for Controlling Scotch Broom

Logging Debris and Herbicide Treatments for Controlling Scotch Broom

Researchers conducted a study near Matlock, Washington investigating the potential of logging debris and herbicide combinations to inhibit germination and development of Scotch broom (Cytisus scoparius) seedlings. The study site was a mature Douglas-fir forest that was scheduled for harvest. The forest understory included occasional Scotch broom plants that invaded from a previous disturbance, indicating the likely presence of soil-stored seed.

Research Studies Support Aquatic Labeling of Aminopyralid

Research Studies Support Aquatic Labeling of Aminopyralid

Field research trials were initiated in ponds and flowing water systems to gather data to support the addition of aquatic uses to aminopyralid product labels. Research was designed to establish food tolerances for fish, shellfish and crustaceans, and define herbicide dissipation in water and sediment over time.
