Resistance Management
The evolution of resistance to various forms of pest management applications is an ongoing concern for all crop protection users. Resistance is not unique to plant biotechnology, although biotech crops do bring some unique considerations which must be addressed by technology providers and farmers.
Plant Biotech Resistance Management
Insect resistant biotech crops provide farmers with excellent protection against damaging pests, however, the development of resistance is an important concern. Insect resistance management techniques such as the planting of refugia, limiting the use of multiple crops with the same insect control traits and planting seed with multiple biotech traits, protect harvests while preserving the long-term effectiveness of the insect resistant crops.
Similarly, herbicide tolerant biotech crops help control unwanted weeds, offering significant yield and environmental benefits. Integrated weed management strategies are key to managing weed resistance. Applying herbicides associated with herbicide tolerant crops according to best use practices can help manage weed resistance.
Plant Biotech Resistance Management
Like all stewardship programmes, resistance management practices require a diverse set of tools, and must evolve and be flexible. Local agricultural conditions will help define what types of resistance management programmes are needed, and they must be continuously reviewed and reconsidered.
CropLife South Africa and its members are committed to advancing the understanding and practice of resistance management, as well as promoting an integrated pest management approach. Integrated pest management (IPM) is when producers consider and incorporate a variety of pest control techniques and other appropriate measures in their pest management programme as opposed to relying on just one method for control.
