"\"Microbial pest control agents are increasingly being investigated for use as alternatives to conventional pesticides because they generally pose a lower potential risk to human health and the environment compared with conventional pesticides. Chontrol Paste represents a potential biological replacement for chemical herbicides. This Proposed Registration Decision is a consultation document that summarizes the science evaluation for Cp-PF2139 and the reasons for the decision. It also describes risk-reduction measures that will be required to further protect human health and the environment.\"--Unedited text from document."@en .

"Chondrostereum purpureum strain PFC2139 is a biological herbicide. This living fungus is formulated into Chontrol Paste and applied to freshly cut stumps of weedy broadleaf brush species in rights-of-way and other forest vegetation management situations. The Pest Management Regulatory Agency decides to grant to the registration for the sale and use of active ingredient Cp-PFC3139 and the end-use product Chontrol Paste for the inhibition of stump resprouting in Sitka and red alder trees.
