These burrs are history

Hand Weeding Khaki Weed
"My advice would be if it is still in small sites try and get rid of it or at the very least monitor its spread closely." --Phil Elson, District Coordinator of the Animal and Plant Control Commission (APCC); State Government of South Australia.
Perhaps the simplest and most-effective way to get rid of khaki weed and prevent its spread, particularly "if it is still in small sites", is to pull it out of the ground by hand--good old-fashion weeding. It is a good idea to get the tap root out, as it is believed to be perennial; while the surface growth comes and goes seasonally.
Successful Eradication of khaki weed relies on eliminating the plant before it sheds its seeds. According to the APCC Khaki Weed Control Notes:
"The key to controlling any weed population is to prevent the plants from reproducing. Hand hoe small infestations before seeds form, ensuring all the tap root is removed."
Protective GLOVES are advisable, because the sharp burr-tips do break off under the skin and cause continued irritation. A standard weeder works okay in soft soils, though a small hand pick might be easier for dense dirt. Some people prefer to use a small, curved-blade, weeding saw.
Hand weeding khaki can be a Zen activity. It is a labor of aloha for the aina, and contributes to cultural preservation. My philosophy is 'every weed eliminated will keep a hundred weeds from sprouting.'
An encouraging note regarding khaki weeding comes from the biologist-photographer team, Forest and Kim Starr (with HEAR): "Best of luck with the effort. We are certain you will be able to make a difference with each plant pulled."
