Phytosanitary needs regarding international trade for plant protection must be met to enable the successful export of high-quality Japanese fruit and tea. A range of measures are needed to prevent pests not native to the importing country from being introduced via exported fruit. Exported foods must also satisfy the maximum residue limits (MRLs) that each importing country sets.
The Quarantine Technology Group develops:
- Phytosanitary measures and pest diagnostic methods that satisfy phytosanitary conditions for fruit export and import.
- Pest control systems for fruit and tea that satisfy the importing countries' MRLs for pesticides.
