Verbenone (SPLAT® Verb) delays Ips typographus (L.) infestation and reduces infestation risk and severity in windthrown Norway spruce in Southwest Germany Open
Outbreaks of European spruce bark beetle, Ips typographus, often follow storms, and can result in losses of Norway spruce, Picea abies, that largely exceed those caused by storms alone. Management actions to reduce P. abies losses attribut…
