Crop specific; Minimum Isolation Distance, Minimum Post-Harvest Land Use Restriction, and Minimum Monitoring Frequency Guidance

Applicants are encourage to review the terms and conditions applied to confined research field trials from the previous year(s) when determining the protocol for conducting future trials. These protocols must be layed out in the "Confined Research Field Trial Application Form (PDF)". If terms and conditions for specific crop species are not available from the previous year(s) then the following tables may be used as a reference. These tables provide guidance, for specific crops, on the minimum isolation distance required during the current year of a trial, the minimum post-harvest land use restriction period and the minimum monitoring frequency imposed on the current year of the trial and the years of post-harvest land use restriction.

Applicants are encouraged to view these terms and conditions as minimum requirements. The PBO may increase or add terms and conditions on a case by case basis depending on the PNT used in the trial and the risk associated with its release under confined conditions.
