Field Guide of Discovery-based Exercises for Organic Vegetable Production
• To make participants aware of and understand the role of repellent and trap crops for pest
management in their own organic vegetable farms; and
• To enhance farmers’ learning experiences by role-playing how repellent and trap crops work as
a management strategy for vegetable pests.
materials
• Organic vegetable fields where pest infestation or non-infestation can be observed on possible
trap or repellent crops; and
• Other office supplies (e.g., Manila papers, notebooks, ball pens, and marking pens).
methodology
• Field walks, role-playing, and brainstorming
steps
1. Divide participants in small groups and ask them to conduct field walks and observe as many
possible repellent and trap crops in adjoining farms of learning field. Interview other farmers,
if necessary. List down all observations related to degree of pest infestation, kinds of repellent,
trap or main crops planted, crop stand, etc.
2. Go back to processing area and prepare for a role-play. A facilitator explains mechanics of play
to the big group and assigns two groups to different repellent or trap crops, one group to a main
crop and two groups to different pests as shown below:
5 Group 1 to repellent-trap crops A (Marigold);
5 Group 2 to trap crops B (Galinzoga parviflora);
5 Group 3 to main crops C (Carrot);
5 Group 4 to pests A (half the group as root knot nematodes; half as diamondback moths);
5 Group 5 to pests B (cutworms)
3. Each small group selects volunteers, discusses, and prepares for their roles. The role-play is
then conducted by the big group to depict the following scenes:
5 The pests shall migrate and pass by different repellent or trap crops;
