Straight glyphosate burnoff increases selection pressure for resistant weeds.

Add a tank mix partner with glyphosate so at least two modes of action are working on target weeds. Even if it’s something as simple as 2,4-D or MCPA, at least you’re incorporating another mode of action. 

It can be tempting to think about just increasing the rate of glyphosate, and calling that good enough for the preseed burnoff. However this will continue to select for glyphosate resistant weeds. Think about how many times in a year we are spraying glyphosate alone out of necessity – in canola, soybean and as a preharvest, and postharvest. There are a lot of options in the preburn, take advantage of them.
