Transboundary Plant Pests and Diseases

Sharing knowledge to prevent and manage TPPDs

In 2018, after two cyclones hit Yemen, Oman and Saudi Arabia, desert locusts found fertile ground to start reproducing out of control, resulting in the worst desert locust crisis in living memory. The locusts quickly spread across Southwest Asia, and the Horn of Africa and threatened the West Africa region.


The Locust Pesticide Referee Group (LPRG) is an independent body of experts that advises FAO on the efficacy and environmental impact of different pesticides for locust control. This advice is based on a critical review of reports submitted by industry, research institutes, plant protection departments, of other available literature, and on the experience of its members and of FAO experts.


The Environmental, Health and Safety (EHS) Standard Operation Procedures (SOP) for the control of the Desert Locust define the procedures that should be followed in a Desert Locust control campaign to minimize the impact of the use of insecticides on human health and the environment.


Over the years, FAO has played a fundamental role in tackling plant pests and diseases worldwide, including locusts. This publication is designed to provide technical officers, stakeholders, policymakers and donors with a better understanding of FAO's role in tackling transboundary plant pests and diseases (TPPDs), including FAO's actions and instruments for TPPDs early warning, prevention, and control.
