Number Risk mitigation measure Effect on the pest Evaluation and uncertainties on bare rooted plants Evaluation and uncertainties on liners
1 Characteristics of the production field Yes The production field condition does not allow isolation of the field used for growing plants for export.Uncertainties:– No uncertainties The production field condition does not allow isolation of the field used for growing plants for export.Uncertainties:– No uncertainties
2 Soil treatment No Not applicable Not applicable
3 Rotation of the growing fields No Not applicable Not applicable
4 Insecticide treatment Yes Pesticide sprays are generally effective against crawlers and less effective against the fixed stages of R. pustulans because of the wax covering of its body.Issues with pesticides resistance should be avoided by rotation of the pesticides.Uncertainties:– There is one uncertainty whether the pesticide can effectively reach all the bark parts where the scales are located because of the barrier effect of the leaves.

5 Fungicide treatment No Not applicable Not applicable
6 Nematicide treatment No Not applicable Not applicable
7 Treatment against weeds No Not applicable Not applicable
8 Plant treatment before export Yes Rinsing of the plants is not removing the pest. Scales can be easily found during inspection with magnifying glasses which is triggered by the observation of suspected symptoms.Uncertainties:– There is uncertainty on the capacity to detect crawlers on the bark with the naked eye. Cleaning of plant debris is not removing the pest. Scales can be easily found during inspection with magnifying glasses which is triggered by the observation of suspected symptoms.Uncertainties:– There is uncertainty on the capacity to detect crawlers on the bark with the naked eye.
9 Sampling and testing No Not applicable Not applicable
10 Inspections during the production Yes R. pustulans are generally detectable except at the crawler stage.Scales can be easily found during inspection with magnifying glasses which is triggered by the observation of suspected symptoms.Uncertainties:– There is uncertainty on the capacity to detect crawlers on the bark with the naked eye.

12 Surveillance and monitoring Yes Surveillance in the surrounding area is not implemented; however, R. pustulans is common in Israel.Uncertainties:– There is no information on the density of R. pustulans in the surrounding areas.
