No. | Risk mitigation measure (name) | Description | Effective | Evaluation/Uncertainties |
---|---|---|---|---|
1 | Certified material |
The Ministerial experts and inspectors carry out the phytosanitary control on mother plants in spring, summer and autumn for harmful organisms, and the amount of propagation materials (grafted plants, budwoods, rootstocks, scions) that can be obtained from mother plants is determined. For the saplings, the phytosanitary control is also carried out at the same time, regarding harmful organisms specified in quarantine and plant passports, and certification regulations. If free from the harmful organisms, the Ministry issues certificates and labels for the propagation material to be taken from plants in the mother blocks. Certified seed or certified seedling is grafted with certified budwood in a certified nursery. Certificate and combined certification‐passport labels are issued by the Ministerial Organization and sent to the producer for the saplings that meet the requirements in the Regulations. |
Yes |
Potential C. baileyi infestations might be overlooked by visual inspection especially in the case of low infestations without using an adequate magnification considering the tiny size of the individuals both adults and juveniles. Uncertainties: The details of the certification process are not given (e.g. number of plants, intensity of surveys and inspections, etc.). Specific figures on the intensity of survey (sampling effort) are not provided. |
2 | Phytosanitary certificates |
Export nurseries must obtain special certification from Turkish Authorities before they begin producing plants for planting. Nurseries must notify technical staff members responsible for production to obtain this certificate, which is then used for registration in the plant passport system. The phytosanitary inspections are done macroscopically. However, if there are signs of disease in the plants or in the immediate vicinity, the inspections are carried out by laboratory analysis. During the production period, official inspection is carried out. After the official approval that the sapling is free from the quarantine factor and true to type, its certificate‐passport label is issued by the Ministry. The Phytosanitary Certificates/Re‐Export Phytosanitary Certificates are issued in exportation of plants and plant products with respect to plant health. In issuing such certificates, the phytosanitary requirements of the importer country are taken into account, in compliance with the ISPM No: 7 and ISPM No: 12 rules. |
Yes |
The procedures applied could be effective in detecting C. baileyi infestations though low densities might be overlooked by visual inspection without using an adequate magnification considering the tiny size of the individuals both adults and juveniles. Uncertainties: Specific figures on the intensity of survey (sampling effort) are not provided. |
3 | Cleaning and disinfection of facilities, tools and machinery | Tools are disinfected with chemical compounds containing 10% chlorine prior to using in sapling and mother plants | Yes |
Cleaning of tools and machineries can lower the possibility of entry and spread. Uncertainties: No details are provided. |
4 | Roguing and pruning | Removal of infested branches | Yes |
Pruning can reduce infestation. |
5 | Biological and mechanical control |
Biological control with different natural enemies (predators and parasitoids) can reduce the pest populations. Nogall (biological control agent) is applied to protect against crown gall. |
Yes |
Phytoseiid species are reported preying on this species. They can be present in the environment though no details are provided in the dossier. Uncertainties: No details are provided on abundance and efficacy of the natural enemies. |
6 | Pesticide application |
The saplings are sprayed against aphids, thrips, whiteflies, red spider pests, black spot, powdery mildew, root rot diseases and, depending on the situation, to fight or protect against weeds. Before loading the plants on the trucks for transport, the roots of seedlings are sprayed with fungicide (Thiram). |
Yes |
Some of the pesticides listed in the dossier might be effective against the mite, specifically acrinathrin and abamectin. Uncertainties: No details are given on the pesticide application schedule and on the application methods. |
7 | Surveillance and monitoring | Necessary precautions are taken to ensure that there are no plants other than certified saplings in the production plot and application areas. Plants closer than 15 m from the plot are not usually available. Plants around the production areas are also annually inspected by the Ministry expert in terms of quarantine organisms. In the event that these plants are contaminated with harmful organisms subject to quarantine, these plants and saplings in this area are destroyed. | Yes |
It can be effective. Uncertainties: Specific figures on the intensity of survey (sampling effort) are not provided and considering the tiny size of the individuals both adults and juveniles. |
8 | Sampling and laboratory testing |
For the identification of viruses, bacteria, fungi and nematodes in the seedlings to be exported, min. 5 to max. 25 seedlings are randomly taken from the plantation in the nursery garden and sealed by the inspector and sent to the laboratory for analysis. Soil samples are taken for laboratory analysis in terms of quarantine organisms, particularly to check if it is free from nematodes. If it is found that the growing medium is free from nematodes, the production of saplings is started. |
Yes |
It can be effective Uncertainties: The modalities and intensity of survey is not known. |
9 | Root Washing | Roots are washed in the washing areas, near the warehouses. | No | |
10 | Refrigeration | The temperature of the storage tanks is between 2°C and 4°C and the humidity is 85‐95%. Transportation is made with refrigerated trucks with the same conditions. | Yes | Low temperatures can slow down its development but not kill the mite. |
11 | Pre‐consignment inspection | Prior to export, planting material for which a Phytosanitary Certificate is to be issued shall be subjected to phytosanitary inspection. Only certified plants for planting may be exported. Phytosanitary inspectors are responsible for export controls, sampling and issuing certificates. | Yes |
The procedures applied could be effective in detecting C. baileyi though the mite presence could be overlooked by visual inspection especially in the case of low infestations without using an adequate magnification considering the tiny size of the individuals both adults and juveniles. Uncertainties: Specific figures on the intensity of survey (sampling effort) are not provided. |
