Herbicide treatments of Japanese honeysuckle for releasing desirable reproduction or for site preparation

Abstract

Various herbicides were used to release pine or hardwood seedlings from competition of Japanese honeysuckle, or to eliminate honeysuckle in areas being prepared for regeneration. Considering both the degree of honeysuckle control and the amount of damage to desired trees, we recommend 2,4-D emulsifiable acid with application in late fall for release of hardwoods and in late summer or early fall for release of pines. A mixture of 2,4-D-picolinic acid applied during spring or early summer is recommended as a conditioning treatment to prepare an area for new regeneration.
