Japanese Beetle Harmonization Plan for Containerized Nursery Stock:

Canada

During March 1994, a U.S./Canada Japanese Beetle Quarantine Harmonized Agreement was signed by agricultural officials in each country. The agreement was the result of four years of negotiations involving agricultural officials and nursery trade groups from both countries. With the loss of chlordane registration, there was a need for alternate treatments and certification procedures. During the last decade, nurseries could only ship to Canada by either immersing and saturating the root balls or containers in a pesticide in order to certify them free of Japanese beetle larvae or shipping the plants bare root. The Japanese beetle harmonization plan has other options for certifying shipments from infested areas in each country to the other country.

Most of Canada is now accepting containerized stock if it meets the following requirements for freedom from Japanese beetle.

• A. When potting plants, no field soil, unless sterilized, shall be used. All plants shall be free of soil prior to transplanting.
• B. Potted plants shall be maintained a reasonable distance away from fences, hedge-rows, sodded areas, flower gardens and other trees and shrubs (a minimum 10 foot weed-free border must be maintained around the container growing area), on material which serves as a ground barrier against Japanese beetle, i.e. gravel, plastic hard packed clay, etc.
• C. Certified lots shall be identified and segregated in a manner satisfactory to an inspector.
• D. All containers shall be maintained free of weeds*

*The established tolerance level to be considered weed free is no more than ten percent weed coverage.
