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 thrips. Issues with pesticides resistance should be avoided by rotation of the pesticides.Uncertainties:– There is uncertainty whether the pest can develop resistance to pesticides, or whether resistant strains spread into the nursery.

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 Pupae and adults can stay in leaf litter/soil so the washing should remove them. However, inspection of soil does not allow to detect their presence.Uncertainties:– The degree of cleaning of roots from soil particles is not defined. Pupae and adults can stay in leaf litter/soil or protected plant parts, so the cleaning should remove them only partly. However, inspection of soil or protected plant parts does not allow to detect their presence.Uncertainties:– The degree of cleaning of litter or plant debris is not defined as well as the thorough check of protected plant parts.
9 Sampling and testing No Not applicable Not applicable
10 Inspections during the production Yes Thrips could go undetected because of the small size of the pest and difficulty in the search in roots and soil particles.Uncertainties:– It is unclear how many samples are required to declare the production site to be free of the pest. Thrips could go undetected because of the small size of the pest and difficulty in the search in litter.Uncertainties:– There is unclear detection limit– The effectiveness of the inspection for R. syriacus is not known because soil is not checked.

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