Pest risk analysis

1. Topic: Pest Risk Analysis (PRA)
Submitted to:

2. - The process of evaluating biological or other scientific and economic evidence
to determine whether a pest should be regulated and the strength of any
phytosanitary measures to be taken against it.
- Pest risk analysis is set of activities, in which the probability and the severity of
impact of a particular pest is assessed.
- It helps to ensure that decisions on the control of imports and exports are based
on sound science, are related to the risks involved and have minimal impact on
trade.
Introduction

3.  To protect the country’s agriculture from damages that can be caused by harmful
(quarantine) pests which can be brought in along with imported commodities.
 To evaluate and manage risk from specific pests and internationally traded
commodities.
 Identify and assess risks to agricultural and horticultural crops forestry and the
environment from plant pests
 To create lists of regulated pests To produce lists of prohibited plants and plant
products
 To assist in identifying appropriate management options
Reason for doing PRA

4. PRA Process Three stages:
Stage 1: Initiation
Stage 2: Pest Risk Assessment
Step 1: Pest Categorization
Step 2: Assessment of the Probability of Introduction
•Entry
•Establishment
•Spread
Step 3: Impacts
Step 4: Overall Assessment of Risk Step 5: Uncertainty
Stage 3: Pest Risk Management

5. Flow chart

6. • Initiation
Point
• Pest or
pathway
for a pest
• Not a
pest
• Identification
of PRA Area
• End

8. It was divided into three steps:
A. Pest Categorization
B. Assessment of the probability of introduction and spread
C. Assessment of potential economic consequences (including environmental impacts).

9. • Step 1 – Pest categorisation
• Identify quarantine pests
• Categorise pests (do they occur on the pathway?)
• Prepare data sheets

Pest 1 Feasible Significant Yes
Pest 2 Feasible Not significant No
Pest 3 Not feasible Significant No
Pest 4 Feasible Significant Yes

11. • Assess the likelihood of entry of a pest- higher no. of pathway- more
probability
• Assess likelihood of establishment of a pest after entry- reproductive
strategy, distribution in PRA area, adaptation, environment suitability
• Assess spread potential of the pest

12. • Include economic ,environmental, and societal impacts
• Include direct or indirect effect to plants
• May be qualitative or quantitive measures of impacts

13. • Impacts on productivity:
– Yield losses
– Increased control costs
– Post-harvest disinfestations
• Impacts on trade / market access:
– Domestic
– International
• Impacts on the environment
• Impacts on human health

15.  Pest Risk Analysis is mandatory for importing any plant or plant materials
The Import Permit issuing authorities shall issue permits for commodities
specified in
Schedule-V,
Schedule-VI and
Schedule-VII of PQ Order, 2003 for which PRA has already been done.

16. Neither the country nor the commodity which have not covered under these
schedules the import permit can not issued
An Importer who intend to import a new commodity or from a country not
covered under the list shall send a specific Pest Risk Analysis Request Form
To
• Plant Protection Adviser to the GOI,
Dept. of Plant Protection, Quarantine & Storage, N.H.-IV., Faridabad-121
001, Haryana.
