Will inter-row application of glyphosate increase the risk of resistance?
Although glyphosate resistance is rare, the use of glyphosate in-crop, such as in shielded interrow spraying, can increase the risk of resistance developing. This is because the use of glyphosate in-crop can expose a greater percentage of a weed population to the herbicide, with limited opportunities for resistant survivors to be controlled before they set seed. The use of inter-row spraying, where registered (e.g. for specific uses in cotton), should be used in conjunction with integrated weed management strategies.
