Field Guide of Discovery-based Exercises for Organic Vegetable Production
Many innovative organic vegetable farmers had tried other yellow trap materials that are more
readily available in their areas. In FFSs, these experiences must be shared among farmers to
improve their current best practices in using yellow trap materials. To enhance learning process,
this participatory, experiential, and discovery-based exercise was designed.
How long will this exercise take?
• Thirty minutes to one hour for field walks, observations, and interaction with farmers; and
• Thirty minutes to one hour for hands-on and brainstorming session.
learning objectives
• To create awareness and understanding among participants about the role of yellow sticky trap
materials in the management of potato leaf-miners; and
• To learn from other farmers their innovative practices in using different yellow sticky trap
materials for management of potato leaf miners.
materials
• Office supplies (e.g., Manila papers, hand lenses, notebooks, ball pens, marking pens, crayons);
• Organically-grown potato crops in learning and adjoining fields showing early infestation of
potato leaf miners; and
• Different yellow sticky trap materials (e.g., made of different materials and shades of yellow colors).
methodology
• Field walks, hands-on, and brainstorming
steps
1. Divide participants in small groups and ask them to conduct field walks and observe as many
organically-grown potato crops with early infestation of potato leafminers in farmers’ fields.
Take note of feeding characteristics of leafminers. Interview other farmers, if necessary.
List down all observations related to pest occurrence, crops or weeds infested, degree and
characteristic of damage, etc. For instance, in a recent field observations and interactions with
officials and farmers in Buguias, Benguet, several important concerns were noted, such as 140 :
