Khaki weed description

Khaki weed identification

Khaki weed is a creeping herb. The root system is perennial but the top growth is annual. The plant has multiple stems up to 60 cm long. These are reddish in colour and feature soft silky hairs. The leaves are round to oval in shape, are usually green with red-purple veins, and grow in pairs along the length of the stem. One of the leaves is significantly larger than its partner and can grow from 5–45 mm in length.

The flowers typically grow in small inconspicuous clusters and are white in colour. The flowers are surrounded by tiny bracts that after fertilisation form small seed-filled prickly burrs that are easily snagged on fur or clothing and footwear, even vehicle and machinery tyres and carried to other areas.

Controlling Khaki weed

When the infestation is small, khaki weeds can be physically removed, ensuring the entire taproot is removed and disposed of by burning to prevent regrowth.

For more extensive infestations it is recommended to use Tordon 75-D as a foliar spray at a rate of 6.5 mL/1 L of water.

Treatment timing

Timing for Khaki weed control

For best results, ensure you treat the plant when it is actively growing; this will ensure maximum uptake of the herbicide and translocation into the root system.
