Glossary
Bacterial wilt, caused by Ralstonia solanacearum, is a bacterial disease of solanaceous crops causing rapid
wilting, stunting, and death in tomato, and wilting of younger leaves or slight yellowing of leaves in
potato. It survives in soil for a long time, infects many plants including weeds, and spreads through
infected seedlings, contaminated irrigation water, farm implements, and animals.
‘Ballot box’ evaluation (BBE) is a simple, easy-to-use pre- or post-training evaluation tool for farmers and
extension workers of their knowledge and skills in integrated pest management IPM). A participant
selects an appropriate ‘ballot box’ where he or she drops his or her code number representing a correct
answer.
‘Barangay’ soil map is a map developed to indicate not only soil types but also location of farmer’s individual
farms. The information contained in a barangay (village) soil map is very useful in determining
appropriate soil management strategies for each soil type as determined by actual field examination and
sharing of experiences among farmers.
Baseline data are agronomic, demographic, socioeconomic, and other related data gathered from farmer field
school (FFS) participants, which are used for comparison with current data when stakeholders review
and assess impact of local integrated pest management (IPM) programs on farmer-participants and their
communities.
Bean fly is a pest of leguminous vegetables belonging to the fly family, whose yellowish to reddish maggots
hatch from eggs to feed as miners, working down the petiole into stem of plants.
Behavior refers to any observable or visible action or activity performed by a learner.
Beneficial insects refer to insect groups that give benefit to farmers in terms of insect pest reduction and
improvement of yield and quality of products. A beneficial insect can either be a parasitoid or a predator
that controls population of pests or pollinators.
Beneficial microorganism refers to a soil-borne organism that gives benefit to farmers in terms of suppressing
harmful soil-borne plant pathogens which consequently improve yield and quality of products. Beneficial
microorganisms interact with harmful microorganisms through competition, amensalism, or parasitism.
Bench terracing is an effective erosion control measure practiced in the Cordilleras, which consists of
creating a series of level strips running across a slope.
Big group discussion is a term used to describe the use of big groups (e.g., plenary sessions) in identifying
and solving problem by participatory discussion.
Biological control is use of living organisms such as parasitoids, predators, and disease organisms to control
pest populations.
Biological control agents refer to any living organism used in reducing pest population in organic vegetable
farms.
