Compliance overview
Scope and applicability
This standard establishes the procedures and methods for the quarantine of cotton seeds in producing areas. It is specifically applicable to plant quarantine institutions at all levels implementing mandatory field inspections and certifications for cotton seed breeding bases. It is essential for agricultural enterprises and seed producers involved in the cultivation and trade of cotton seeds within China. The protocol specifically focuses on preventing the spread of quarantine pests, notably Verticillium dahliae (Cotton Verticillium wilt).
Technical requirements
GB 7411-2009 outlines the comprehensive operational procedures for plant quarantine. It dictates the requirements for site selection, application processing, and strict field investigation protocols. The standard mandates specific survey timings based on the occurrence patterns of quarantine pests and the growth stages of the cotton plants. The technical framework requires visual field inspections combined with targeted sampling methods. For instance, when investigating Cotton Verticillium wilt, inspectors must select specific susceptible field plots and conduct systematic plant-to-plant examinations for characteristic symptoms like vascular discoloration. Suspected infected plants must be properly sampled, labeled, and transferred for laboratory testing. Furthermore, the standard defines the protocols for epidemic handling. If a quarantine pest is confirmed, the infected seeds must undergo strict disinfection treatments and are restricted to use within the epidemic area only. Seeds from infected fields are strictly prohibited from being transferred to disease-free zones. Finally, the standard specifies the issuance of a Quarantine Certificate for qualified bases and mandates that all inspection archives be preserved for a minimum of two years.
Testing methods
The standard employs a combination of field and laboratory testing methods. Field inspections involve visual assessments of pest damage characteristics and morphological features, utilizing systematic parallel jumping sampling methods. Laboratory testing is required for suspected samples, utilizing specific isolation and culture techniques, such as cultivating vascular bundles on 2% water agar and PSA plate media to identify pathogen structures like verticillate conidiophores and microsclerotia. The standard also details seed disinfection treatments, including mechanical acid delinting and chemical seed dressing, to eliminate pathogens.
