Why CABI created the Crop Pest Diagnosis Course

CABI designed the Crop Pest Diagnosis Course to support teachers, trainers and practitioners in agricultural education institutions and in the workplace. They provide interactive exercises and resources to help participants learn about diagnosing and managing pests & diseases. 

The materials work equally well for self-study, providing all the required information and context. 

We believe that digital media can complement other traditional forms of training to deliver high-quality, more accessible, self-paced and adaptive learning that will help learners acquire and implement skills to make them more productive.
