Following the step-by-step process laid out in these case studies, the diagnostician is trained to approach each crop disease situation in the same manner. This reduces bias and can lead to a more accurate diagnosis. Through this series of steps, we will:

2. Determine what additional questions or diagnostic techniques may need to be addressed
3. Decide what action, if any, will improve the situation (recommendations)
