Demonstration of how to observe with foldscope

          Demonstration of infected plant parts under foldscope-

          As majority of the participants were farmers from different regions of India, we described simple slide preparation by using a regular slide and placing the infected plant part on the slide. After this by using transparent tape, we can prepare our temporary slide and observe under foldscope.

Observation under foldscope, (a, b)image showing the temporary slide preparation of infected sugarcane, (c,d) non infected vs infected sugarcane under foldscope
observation of infected banana leaf under foldscope, a. infected leaf was taken as a sample, b. a temporary slide was prepared, c. observation under foldscope

After this various prepared slides were demonstrated using foldscope.

Conclusion- Foldscope can be useful tool for capturing the infected crops and identification on field. The workshop was a success.
