The Potato Cyst Nematode (PCN) Scenario Planner is a free to use, web-based tool designed to help professional potato growers and agronomists assess PCN risk and forecast potential yield loss without requiring laboratory integration or field mapping data.

Users enter estimates of PCN population levels for each species, Globodera pallida and Globodera rostochiensis, along with information about their region, crop rotation, and planned potato varieties. The system then models how PCN populations are likely to change over time and predicts how these changes could impact yield under different management strategies.

Key Features

• Models population change for both PCN species.
• Estimates yield loss based on population pressure and variety tolerance.
• Simulates the effects of rotation length, variety selection, resistance levels, and management decisions.
• Displays graphs showing expected changes in PCN levels and yield over multiple rotations.
