Growing metabolism-based resistance is the greatest problem no-tillers will face with weed control, but effective use of herbicides, using multiple modes of action, and controlling the weed seed bank at harvest can all help.

With more and more herbicide resistance in weeds being reported and no promising new herbicide sites of action (SOA) waiting in the wings, no-tillers might do well to focus on integrated weed management systems to reduce weed pressure and extend the usefulness of existing herbicides.

When we asked attendees at last winter’s National No-Tillage Conference about their experiences with weed-resistance concerns, they cited a number of instances from their own fields

As you make burndown weed control decisions for 1999, make sure that you fully understand all of your herbicide options.
