Weed Control in Bareroot Hardwood Nurseries

Abstract

Managers in the southern United States rely on chemical and non-chemical methods of weed control. Chemical treatments include fumigation with methyl bromide and chloropicrin in combination with selective herbicides. If methyl bromide is no longer produced in the future, the amount of handweeding will likely increase unless managers 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 formulations can injure seedlings if applied to seedbeds. Grasses can be effectively controlled with selective herbicides and many small-seeded broadleaf weeds can be suppressed with preemergence herbicides. Several nursery managers have fabricated shielded herbicide sprayers to apply herbicides between drills.Individual papers from this publication
