ABSTRACT / Throughout Central America, the United States
Agency for International Development (USAID), and the
Zamorano Pan-American Agricultural School support a Safe
Pesticide Use program. In 1993, a study of results was
carried out among farmers and housewives in eastern
Guatemala. Aspects of the methodology included: (1)
participation of extension workers in all aspects of the study;
(2) small, region-focused samples (eight cells, 30 interviews
per cell); (3) comparison to control groups of untrained
farmers and housewives; (4) a traditional questionnaire for
studying acquisition of specific knowledge; and (5) a flexible
instrument for building a cognitive map of knowledge and
beliefs regarding pesticides. The cognitive map is a step
toward applying modern psychocultural scaling, an approach
already well developed for medicine and public health, to
environmental problems. Positive results detected include
progress at learning the meaning of colors on containers that
denote toxicity and where to store pesticides. Pesticide
application problems detected were mention by farmers of
highly toxic, restricted pesticides as appropriate for most
pest problems and of insecticides as the correct solution to
fungus problems, and the widespread belief that correct
pesticide dosage depends on number of pests seen rather
than on land or foliage surface. Health-related problems
detected were admission by a vast majority of housewives
that they apply highly toxic pesticides to combat children's
head-lice; low awareness that pesticides cause health
problems more serious than nausea, dizziness, and head-
aches; and a common belief that lemonade and coffee are
effective medicines for pesticide poisoning.
Origins of This Study
At this point in human history, agriculture and food
supply depend on chemical pesticide use. Unfortunately
throughout the world, overuse and misuse of chemical
pesticides in agriculture cause environmental and
health damage, and Central America is no exception
(Leonard 1987, World Resources Institute 1993,
Thrupp 1994, RPC-ICAITI-CINTEGRA, S.A. 1994). The
environmental damage is through soil and water con-
tamination and through raising resistance to pesticides
of pests and their natural predators. Damage to human
health by pesticides is to producers of agricultural prod-
ucts and their families who handle pesticides and con-
taminated objects and to the populace in general
through consumption of agricultural products and
through water and soil contamination.
What people in rural areas know and believe about
the uses and effects of pesticides determines in large
part how pesticides are applied and managed. To up-
grade farmers' and their families' knowledge regarding
pesticides, and thereby improve pesticide management
practices, the US Agency for International Development
(USAID), through its Regional Natural Resource Man-
agement (RENARM) project, has supported a Safe Pesti-
cide Use campaign in the countries of Central America.
Within the Safe Pesticide Use campaign in Central
America, the organization responsible for development
of training materials and for training extension agents is
the Zamorano Pan-American Agricultural School in
Honduras. In 1993, the Zamorano School requested as-
sistance from Management Systems International (MSI)
in studying the effects of their efforts. As a laboratory for
development of instruments and methods, training and
extension activities with farmers and housewives in east-
ern Guatemalawere chosen. Throughout Guatemala the
Safe Pesticide Use program is a joint effort among not
only the Zamorano School, but also DIGESA (the Guate-
malan government's General Directorate for Agricul-
tural Services), and Agrequima (an office of the agribusi-
ness-based GIFAP network headquartered in Belgium).
