As the pressure increases to develop safer and more economical herbicides, the Government is forced to either withdraw or restrict some of the older chemicals. Table 3 provides a list of the restricted and banned herbicides used in South Africa. It is important to have this list handy so that anybody using these chemicals can be notified. When a substance is “withdrawn” it implies that there may still be some limited uses for the product but when it is “banned”, it may not be used at all.Some of the banned and withdrawn substances as published in the South African Government Gazette over the years.
