• Thirty minutes to one hour for brainstorming session in processing area.
learning objectives
• To make participants aware of and understand the role of proper uprooting and disposal in
management of tymo virus disease of chayote; and
• To learn from other farmers proper uprooting and disposal in management of tymo virus disease
of chayote.
materials

learning and adjoining fields;
• Office supplies (e.g., Manila papers, notebooks, ball pens, and marking pens); and
• Other supplies (e.g., plastic bags, cutting, and digging tools, basket, match or lighter, etc.).
methodology
• Field walks and brainstorming
steps
