How do I control Carrot Weed?

Description:
Carrot Weed, also known as Wild Carrot, is a fern-like annual or biennial weed that closely resembles Parsley Dropwort. It features delicate white flowers arranged in umbrella-shaped clusters (umbels), often with long, narrow bracts beneath each bloom. Growing upright to about 1–1.2 metres tall, the plant is covered in fine hairs and has a distinctive white taproot.

Where it’s found:
Widespread across New Zealand, Carrot Weed is commonly seen along roadsides, in pastures, on cultivated land, waste areas, and even in home gardens. It thrives in sandy or moist soils but is also known to grow in minimal soil environments like gravel or roadside edges.

Control Methods:

• In Turf:
  Apply Vivendi at 1L/ha combined with Result Spray Oil at 1L/ha.

• In Pasture:
  Use Clout Amine at 2–3L/ha with Result Spray Oil at 1L/ha. For best results, apply treatment before the plant begins to stalk.
