PEST RISK ANALYSIS (PRA) TRAINING Group Exercises Manual

PEST RISK ANALYSIS TRAINING - GROUP EXERCISES MANUAL GROUP EXERCISE NO. 8
Example No. 2 – Raspberry Ringspot Nepovirus
SCENARIO: The Plant Quarantine Organisation of India (Ministry of Agriculture)
has received a request to import a new variety of raspberry canes from Europe for
multiplication and propagation in India. Production of temperate fruits in India is on
the rise; deciduous fruits including pome fruits (apple and pear) and stone fruits
(peach, plum, apricot and cherry) are produced in considerable quantity and soft
fruits are similarly increasing in popularity. Soft fruit production in India, namely
raspberry, strawberry, cherry and grape, was estimated at just over 1 million tons in
2004, with an export value of 25 million USD.
A PRA has been initiated to determine the risk to India’s soft fruit industry presented
by the potential importation of canes from Europe. A preliminary review of pests in
Europe has focussed concern on raspberry ringspot nepovirus (RRSV).
