I've done a few searches and come up with some conflicting advise on what adjuvant to use with Drive 75. Yes - I know the label reads MSO.... but it can be hard to find. Some use Lesco spreader sticker (non-ionic) and say they have good results with it. Other posts say it doesn't work and only MSO will deliver results. Which is true? I already have Lesco sticker and am only concerned with post-emergent crab grass control. Thanks.
