Research

Fundamental research was conducted to understand the biology of the active ingredient C. purpureum and its role in natural forest ecosystems of North America. Applied research was also conducted to determine the safety of C. purpureum for non-target species and to determine its effectiveness as a biological control agent. This section provides copies of the supporting research completed to demonstrate product safety and efficacy, prior to its registration as a biological herbicide.
