This publication reports research involving pesticides. It does not contain recommendations for their use, nor does it imply that the uses discussed here
have been registered. All uses of pesticides must be registered by appropriate State and/or Federal agencies before they can be recommended.
CAUTION: Pesticides can be injurious to humans, domestic animals, desirable plants, and fish or other wildlife—if they are not handled or applied
properly. Use all pesticides selectively and carefully. Follow recommended practices for the disposal of surplus pesticides and pesticide containers. The
Forest Service, United States Department of Agriculture, has developed this information for the guidance of its employees, its contractors, and its
cooperating Federal and State agencies, and is not responsible for the interpretation or use of this information by anyone except its own employees. The
use of trade, firm, or corporation names in this publication is for the information and convenience of the reader, and does not constitute an endorsement by
the Department of any product or service to the exclusion of others that may be suitable.
