Section 5 • Integrated Disease Management
2. Go back to processing area, brainstorm in small groups and present output to the big group.
Conduct participatory discussions to allow sharing of experiences among participants and
facilitators. As a wrap-up session, agree in big group how to improve some procedures provided
below:
5 Break eggs and separate yolks from white;
5 Macerate egg yolk with small amount of water for 3-4 minutes;
5 Put one (1) yolk to 60 ml cooking oil in container and mix thoroughly;
5 Allow emulsion to stand for 5 minutes before mixing it with water for spraying;
5 Mix 48 ml of EYCO emulsion to 16 liters of water and spray to plants in early morning or
late afternoon (e.g., not in heavy sunlight);
5 Prepare 0.3% solution for protective spray application or 0.5% solution for curative spray
application; and
5 Monitor sprayed plants weekly (use marker in affected area for reference).
3. Go back to learning field and do hands-on on preparation and use of egg yolk + cooking oil
(EYCO) for management of powdery or downy mildews in organically-grown vegetables in
small group.
4. Return to processing area, process output in small group, and share experiences and lessons
learned to big group.
5. Synthesize and summarize output of small groups into one big group output. Draw up
conclusions and recommendations from this exercise.
some suggested questions for processing discussion
❏ What organically-grown vegetables were infected with powdery or downy mildews? Did you
observe differences in crop stand, disease severity, and others among different organicallygrown
vegetables?
❏ What are commonest organically-grown vegetables infected with powdery or downy mildews
in nearby areas?
❏ What benefits can be derived from using egg yolk + cooking oil (EYCO) for management of
powdery or downy mildews in organically-grown vegetables?
❏ When is most appropriate time to use egg yolk + cooking oil (EYCO) for management of
powdery or downy mildews in organically-grown vegetables?
❏ What innovations did you learn from other farmers in using egg yolk + cooking oil (EYCO) for
management of powdery or downy mildews in organically-grown vegetables?
