Can tillage lower the risk of glyphosate resistant weeds?
Yes, but only if the rare glyphosate resistant survivors are killed by the cultivation. For this to happen, the cultivation needs to be well timed and executed. For example, by acting as a double knock, full-cut cultivation at seeding following a knockdown glyphosate application will considerably reduce the chance of any rare glyphosate resistant plants surviving and therefore reduce the risk of glyphosate resistance.
