The Nuclear Stock Association Ltd (NSA)
The Nuclear Stock Association Ltd (NSA) provides a service to the fruit industry through the supply of pedigree high health planting stock of commercially grown fruit varieties to the propagation industry.
This is achieved through co-operation with The Animal and Plant Health Agency (APHA) in the successful operation of the Fruit Propagation Certification Scheme (FPCS) and the voluntary Plant Health Propagation Scheme (PHPS).
The FPCS works to the standards laid down by the EU Certification Scheme and follows the same health grading system. The PHPS is a long established voluntary certification scheme, which oversees the Approved-Health (A-H) grade for soft fruit and the certification scheme for Hops. The aim of the schemes is to promote the production and use of certified healthy proven planting material from high quality parent stock.
The NSA produce the highest health pre-basic and basic grade stock. Propagators use these certified stocks to produce healthy plants for supply to fruit growers.
