PP 1/323 (1) Evaluation of mating disruption techniques against Lepidopteran pests in grapevine, pome and stone fruits under semi‐field conditions

Specific scope This Standard describes the conduct of trials employing the CIRCE methodology (Cage method for Investigation of pheromone effects by Release and Capture, described by Doye and Koch, 2005) for the evaluation of the potential of products intended for mating disruption of relevant Lepidopteran pests in grapes and pome and stone fruit. Trials following this methodology do not replace the need for large‐scale field trials, but data from such semi‐field studies can be used as part of a registration data package supporting the potential of a given pheromone product to prevent mating in the proposed uses. The Standard should be read in conjunction with the general principles described in PP 1/264 Mating disruption techniques and in PP 1/296 Principles of efficacy evaluation for low‐risk plant protection products . Standard PP 1/314 Evaluation of mating disruption techniques against Lepidopteran pests in grapevine, pome and stone fruits under field conditions describes trials under field conditions. Specific approval and amendment First approved in 2020–09.
