Fungicides are chemicals that can inhibit the growth or development of fungal pathogens. They are important tools that farmers use proactively to protect and maintain plant health, quality and yield.
Certain species of fungi can become resistant to fungicides. This not only diminishes the fungicide’s long–term effectiveness but can reduce the amount of food brought to market.
CropLife South Africa has a regional specialist working group, the Fungicide Resistance Action Committee (FRAC), comprising of industry experts to provide fungicide resistance management guidelines in the South African landscape.

Herbicides are essential tools used by farmers to protect crop yields and quality by controlling weeds that compete with plants for nutrients, sunlight, space and water.
Herbicides allow farmers to control weeds and preserve their crop’s yield and quality. If farmers rely too heavily on one type of herbicide, however, weeds can naturally adapt and become resistant.
CropLife South Africa has a regional specialist technical working group, the Herbicide Resistance Action Committee (HRAC), comprising of industry experts, with the objective to promote the correct and responsible use of herbicides, to monitor new herbicide resistance cases in South Africa, to develop integrated management strategies for herbicide-resistant weeds and to provide and disseminate information about weed resistance.

Insecticides are valuable tools used by farmers that can contribute to efficient food production because they control invertebrates that reduce a crop’s yield and quality.
While insecticides are among the most effective tools for controlling pest populations 2, all farmers are challenged by the fact that every insect control method has a limited life span because pests naturally evolve and become resistant.
CropLife South Africa has a regional specialist technical working group, the Insecticide Resistance Action Committee (IRAC), comprising of industry experts to facilitate communication and education on insecticide resistance and to promote the development of resistance management strategies so as to maintain efficacy and to support sustainable agriculture and improved public health in the South African landscape.

Rodenticides are valuable tools used by farmers and pest management professionals to protect human and animal health from rodents, which can spread disease and destroy food crops and property.
Fifty years of research shows that the use of anticoagulant rodenticides, which prevent blood clotting, is the most effective method for controlling rodent infestations. The continued use of the same rodenticides can lead to the development of resistance in some rodent species. 1
CropLife South Africa has a regional specialist working group, the Rodenticide Resistance Action Committee (RRAC), comprising of industry experts to develop an understanding of resistance and resistance management in order to maintain the effectiveness of currently available rodenticides in the South African landscape.
