Compliance overview
Scope and applicability
This standard specifies the quarantine protocols and procedures for propagating tubers and seedlings of sweet potato in producing areas. It is applicable to agricultural plant quarantine institutions conducting mandatory origin quarantine for sweet potato seedlings. It does not apply to the quarantine of processed sweet potato products or post-harvest commodity quarantine in transit. The standard is essential for agricultural producers and quarantine authorities involved in the breeding and distribution of sweet potato planting materials.
Technical requirements
The standard outlines the comprehensive technical requirements for the quarantine process, which is divided into several critical phases. First, it defines the quarantine pests to be regulated, including those listed by national and provincial agricultural authorities. The protocol requires production units to submit an application for origin quarantine, which is reviewed by the plant quarantine institution. During the production phase, the standard mandates specific field investigation procedures. This includes visual inspections and random sampling at three key stages: the seedling raising period, mid-growth, and before harvest. The sampling intensity is strictly defined, requiring inspection of no less than 10% of the propagation area. Any discovery of quarantine pests necessitates immediate cessation of seedling raising and mandatory pest eradication measures. For indoor detection, the standard specifies the collection of suspicious symptomatic plants or tubers for laboratory testing. If no quarantine pests are found after both field and laboratory examinations, a Quarantine Certificate is issued, which is valid for one year. The standard also includes detailed guidelines on epidemic handling, requiring the destruction of infected materials and the rotation to non-host crops in affected areas.
Testing methods
The standard involves two primary testing approaches: field inspection and laboratory detection. Field inspections rely on visual assessment of pest damage symptoms and biological characteristics, with specific sampling methods for different growth stages. Laboratory detection includes the collection of symptomatic specimens and surrounding soil, followed by microscopic examination. For specific pests like the rot stem nematode (Ditylenchus destructor), the standard references detailed separation methods such as the Baermann funnel technique and shallow plate method, as well as morphological identification under a microscope.
FAQs
What products are regulated under GB 7413-2009?
GB 7413-2009 regulates the propagating tubers and seedlings of sweet potato in their production areas. It is designed for agricultural plant quarantine institutions to ensure that sweet potato planting materials are free from designated quarantine pests before distribution.
Are there any updates from the previous version of GB 7413-2009?
Yes, GB 7413-2009 replaces the older GB 7413-1987. The main updates include modifications to the English name, standard structure, and terminology. It also supplements the procedures for origin quarantine, including investigation, detection, and epidemic handling.
What happens if quarantine pests are found during the inspection?
If quarantine pests are detected, seedling raising must be immediately stopped. The infected seedlings and tubers must undergo quarantine eradication treatment or be destroyed on-site through burning or deep burial. The affected fields and surrounding areas must be rotated to non-host crops.
