I like this combination in no-till corn where Canada thistle is up at planting time. Burns the thistles down. As mentioned above, I prefer preemergence applications of Broadstrike with IR corn lines. Liberty herbicide is part of the Liberty-Link program developed by AgrEvo. Liberty does a nice job postemergence on many annual grass and broadleaf weeds.
Large grasses are a weakness.
From what we've seen over the years, you may need to put a grass product down at planting and then come back with Liberty. Using Liberty alone has generally required two applications where severe weed pressure exists. This one scares me from a resistance management standpoint. It's very similar to Roundup and acts pretty much the same way. As with corn, we have a number of new products coming to the market place real soon.
