Escopo e aplicabilidade
GB 5040-2003 applies to the plant quarantine of citrus nursery stocks in producing areas within China. It is designed for use by plant quarantine authorities and all citrus seedling breeding units or individuals. This standard is mandatory for all citrus nurseries operating in China. It specifically targets the prevention and control of five major quarantine pests, including Citrus Huanglongbing and Citrus Canker.
Requisitos técnicos
The standard specifies the quarantine pest categories, nursery site selection, and propagation material disinfection protocols. It requires nurseries to be located in pest-free areas with specific isolation distances from other citrus plants, such as a minimum of 3 km in plains or 1.5 km in mountainous areas for Huanglongbing prevention. Breeding units must submit a quarantine application to local authorities before commencing operations. It outlines strict nursery epidemic prevention measures, including the prohibition of un-disinfected citrus materials, mandatory tool sterilization using 10% bleaching powder or 1% sodium hypochlorite, and strict control of the Asian citrus psyllid. Personnel entering nurseries must change into dedicated protective clothing. Compliance with these biosecurity protocols is essential for certification. The standard details disinfection techniques for seeds and scions. Seeds must undergo hot water treatment at 55°C±0.3°C for 50 minutes, while scions require specific chemical soaks involving tetracycline and streptomycin sulfate solutions. These procedures are defined in the normative appendices Appendix A and Appendix B.
Métodos de ensaio
Testing involves field inspections conducted by quarantine officers at specific growth stages (after summer and autumn shoots turn green, and before nursery exit). Inspectors use random sampling methods based on nursery size. Suspected infected samples must be sent to laboratories for confirmation. Laboratory identification methods include symptom observation, pathological anatomy, pathogen isolation on BPG medium, in vitro leaf enrichment, serological tests (ELISA and IF), and PCR technology for Huanglongbing detection.
