The protesters are on Bakkies adorned with crosses, cars with banners saying “Stop Farm killings” and “enough is enough” while protesters are wearing white t-shirts with red handprints on their hearts.
They will be addressed by Unite Against Farm Murders and Attacks, Kallie Roux, before handing over their memorandum to government.
Unite Against Farm Murders organisation embarks on a protest to the Union Building:
Roux says it is about raising awareness and praying for farmers, but also a call for people to get involved in security structures in rural areas.
Some major routes around Pretoria to the Union Buildings will be disrupted until about noon on Saturday.
The killing of the Normandien farm couple, Glenn and Vida Rafferty, has re-ignited fears in the farming community.
The Raffertys were ambushed and shot dead as they entered their home on their farm last week.
