Pesticide manufacturers had already submitted products for approval, and products for controlling the pest were already available on the market, according to a DAFF statement.

In the interest of human safety and pest resistance management, the department encouraged the use of registered products in terms of the Fertiliser, Farm Feeds, Agricultural Remedies and Stock Remedies Act (No. 36 of 1947).
