Since their introduction, growers have rapidly adopted herbicide-tolerant biotech crops to help control unwanted weeds that compete with the crop for light, nutrients and water. These crop varieties are able to tolerate exposure to specific herbicides that would normally harm them, representing a major advance in weed control. By protecting crops against weeds, these crops offer significant yield and environmental benefits, while improving farmer livelihoods.
However, weed management challenges such as herbicide resistance, weed shifts, yield performance, gene flow and herbicide draft are an important concern for all stakeholders, including growers, technology providers, and the seed companies that develop biotech-derived crops. Given the benefits associated with herbicide resistant seed, integrated weed management is a critical strategy for growers that considers the use of all economically available weed control techniques without relying on only one.
Importantly, integrated weed management is equally applicable for all types of farming systems, and growers are encouraged to implement these strategies for conventional and biotech-derived crops.
To help growers and suppliers provide accurate information on proper integrated weed management in agriculture, CropLife International and its partners have assembled an Integrated Weed Management Manual as a resource.
