Evaluations of Control Agents for Conifer Seed Protection

Source

Standardized test procedures have been developed for evaluating repellent and toxic treatments on Douglas-fir (Pseudotsuga menziesii) and toxic baits for use against deer mice (Peromyscus maniculatus)—a primary target species in the Pacific Northwest. This sequential series of repellent and toxicant evaluations includes various bioassay, phytotoxicity, enclosure, hazard, and field studies with each step providing more detailed information on the properties, efficacy, and potential hazards associated with specific candidate chemicals. The primary objective of these evaluations is to provide a safe, effective method to achieve the minimum stocking criteria of 7400 Douglas-fir seedlings per hectare.
