262 Field Guide of Discovery-based Exercises for Organic Vegetable Production 5. Summarize and synthesize all learning experiences shared. Draw up conclusions and recommendations from this exercise. some suggested questions for processing discussion ❏ What part of your body was contaminated with white powder material when you walked over a field? How did the white powder material contaminate your body? ❏ Did the white powder material applied in a field move to other areas? How? ❏ Did the white powder material that contaminated your body move to other bodies or areas as you walked in a field? How? ❏ Were there still white powder materials left in your body after leaving a field? Where did the white powder material go? How? ❏ Do you think vegetable diseases can be transported in the same way? What made you think so? ❏ Can farm tools transport vegetable diseases to other areas? Do you know of other means by which vegetable diseases can be transported to other places? ❏ Can we manage vegetable diseases by knowing how they are transported to other places? How? ❏ What practical cultural management practices can you suggest that will avoid transport of vegetable diseases from one place to another?
Section 5 • Integrated Disease Management Exercise No. 5.03 178 WATER FLOATING TECHNIQUE: DETERMINING THE PRESENCE OF GOLDEN CYST NEMATODES IN ORGANIC POTATO FIELDS BaCKGroUND aND raTIoNalE Golden cyst nematode is one of the most destructive pests of potato. At high population, cyst nematodes can inflict serious damage to vegetable crops. Symptoms on above ground plant parts resemble that of drought injury or nutrient deficiency. Most farmers are not aware that their fields are infested by cyst nematodes. A practical and appropriate tool should be available for them to determine presence of these harmful organisms in their fields. Thus, water-floating technique is a very useful tool for farmers in assessing golden cyst nematode infestation in their own fields. In this foregoing exercise, living and squirming nematodes will be impressive to see, particularly for farmers who do not even know they exist 179 . How long will this exercise take? • One hour and thirty minutes for field walks, and observations in learning field and hands-on exercise in processing area; and • Thirty minutes to one hour brainstorming session. learning objectives • To make participants aware and understand how proper identification of golden cyst nematodes contributes to better management of the problem in organic vegetable fields; and • To learn how to identify golden cyst nematode infested fields and experience how living nematodes look like. 178 Adapted from Callo, Jr., D.P., L.B. Teofilo, and H.A. Tauli (eds). 2002. Field Guide of Discovery-based Exercises for Vegetable IPM, Volume II. SEAMEO Regional Center for Graduate Study and Research in Agriculture (SEARCA), Los Baños, Laguna, Philippines. pp 221-222. 179 IIBC. 1996. Integrated Pest Management for Highland Vegetables, Volume 4: Training Guide for Participatory Action Towards Discovery Learning. International Institute for Biological Control, BPI Compound, Baguio City, Philippines. pp110. 263 when is this exercise most appropriate? ɶ In FFS, TOT, and VST sessions, when existing farmer’s fields are possibly infested by golden cyst nematodes; and ɶ When farmers want to experience how live cyst nematodes look like and learn how other farmers manage them in their fields.
