Weed Control in Southern Hardwood Nurseries

In the South, most nursery managers have relied on methyl bromide for weed control in hardwood seedbeds. When methyl bromide is no longer available, handweeding times will likely increase unless management regimes adapt to the change. Some nursery managers will increase use of both sanitation practices and herbicides. Although several herbicides are registered for use on hardwoods, some can injure seedlings when applied to seedbeds. Grasses can be effectively controlled with selective herbicides. Many small seeded broadleaf weeds can be suppressed with preemergence herbicides. Information on registered herbicides for hardwoods is provided.
