Section 5 • Integrated Disease Management
In farmer field schools (FFSs), such innovative experiences can be shared with farmers to improve
their current practices in managing damping-off disease of organically-grown tomatoes. This
exercise is meant to address this particular concern.
How long will this exercise take?
• Thirty minutes to one hour field walks, farmer interviews, and observations prior to or during
seedbed preparation of learning and adjoining fields previously grown with tomatoes infected
with damping-off disease;
• Thirty minutes to one hour hands-on on using Trichoderma as biological control agent against
damping-off in tomatoes before or during seedbed preparation in learning field; and
• Thirty minutes to one hour brainstorming session in processing area.
learning objectives
• To make participants aware of and understand how Trichoderma can be used as biological
control agent against damping-off in organically-grown tomatoes; and
• To learn some innovative practices in using Trichoderma as biological control agent against
damping-off in organically-grown tomatoes.
materials
• Seedbeds of learning and adjoining fields previously grown with organic tomatoes infected
with damping-off disease;
• Office supplies (e.g., Manila papers, notebooks, ball pens, and marking pens); and
• Other supplies (e.g., Trichoderma pellet or powder, spade, bolo, and others).
methodology
• Field walks, hands-on, and brainstorming
steps
1. Divide participants in small groups and ask them to conduct field walks and observe learning
and adjoining fields previously grown with organic tomatoes infected with damping-off disease.
Interview other farmers, if necessary. List down all observations related to pest and disease
occurrence, kind of crops planted, crop stand, etc.
