Plants vs Pathogens
Nature's game of detection and evasion

Vegevaders is a board game that allows students to experience through game-play the continuing co-evolution between plants and their microbial pathogens that occurs during the battle to detect/defend (plants) versus evade/invade (pathogens). The game has been successfully play tested with Middle School, High School, and Community College level students.

The version of Vegevaders made available here is a prototype to be used exclusively for testing, evaluation, or quality control purposes. Developers shall not be liable for any damages that result from the materials on this site or the performance of the products
