PRACTICES AND KNOWLEDGE ON ENVIRONMENTAL AND
HEALTH HAZARDS OF FARM PESTICIDE USE
Kenneth D. Barrientos
ABSTRACT
The study was conducted to find out the practices and knowledge on
environmental and health hazards on farm pesticide use by rice farmers in the
seven agricultural barangays in the Municipality of Ibajay, Aklan. Data were
collected from the 99 rice farmers and 76 barangay officials from January to
February 2013 using an interview schedule translated in the Aklanon dialect to
elicit information.
Results showed that the respondents were mostly males, 43 years old,
married, and finished secondary education. Most of the farmers were landowners
with an average size of 1 ha. irrigated farmland. They had participated in local
governance and members of associations. All farmers used insecticides to
control rice pests. Most of them safely applied pesticides using knapsack
sprayer, wore long-sleeves, long pants and face mask. They stored pesticides
safely by burying empty pesticide containers and some were burned.
Farmers acquired their knowledge on pesticides from the Agricultural
Technologists of LGU Ibajay assigned in the municipality. The health problems
experienced associated with pesticide mishandling were skin rashes, redness of
skin, discoloration of toe nails, shortness of breath, vomiting, itching of eyes ,and
blurred vision. Generally, farmers had knowledge on the environmental and
health hazards of pesticides.

INTRODUCTION
Pesticides are important agricultural input used to eliminate pests and
ensure increase rice production. However, studies shows that the unsystematic
use of pesticides had resulted to ecological imbalances of farming system,
worsening pest problems and creating harmful effects on environment and
human health (Oczon, 2012; Rola and Pingali, 1993). Kedia and Palis (2008)
revealed that the farmers lack of awareness and limited knowledge on the
dangers of using pesticides were due to their difficulties to comprehend the
complex agrochemical label instructions and health safety information of the use
of pesticides.
Rice farming is one of the major sources of income in the municipality of
Ibajay, Aklan. Ibajay has a total population of 45,279 (Census of population and
Housing, 2010) with 25 barangays engaged in rice farming. Most of the farmers
attended trainings and seminars in rice production. However, increased
production was given much attention rather than health and safety of farmers on
the use of pesticides. Hence, this study attempted to examine the practices and
knowledge of rice farmers on environmental and health hazards due to pesticide
use.
Statement of the Problem
The study aimed to determine the practices and knowledge on
environmental and health hazards of pesticide use in the municipality of Ibajay.
Specifically, the study aimed to answer the following questions:
1. What is the socio-demographic and economic profile of the respondents in
terms of age, gender, educational attainment, marital status, number of
children, number of years in farming, total area of farmland, type of farm,
ownership of land, source of farm input, average rice production per
cropping, and participation in local governance and associations?
2. What are the kinds of pesticides used by the farmers?
3. What are the practices adopted in handling, application, and disposal of
farm pesticides?
4. What are the sources of knowledge on pesticides?
5. What are the symptoms associated with mishandling pesticides?
6. What is the knowledge of the respondents on the environmental and
health hazards of using pesticides?

Sampling Techniques
The sampling technique used in the study was the stratified/proportionate
random sampling with a random start.
Research Instrument
An interview schedule was used to get the needed information from the 99
farmers and 76 barangay officials. The interview schedule was translated in the
Aklanon language to be easily understood by the respondents. Most questions
asked were based from the United States Environmental Protection Agency
(1991) regarding safe pesticide use.
Data Gathering Procedure
The researcher secured an approved letter from the Municipal Mayor of
Ibajay to administer the interview schedule. Assistance from the Barangay
Captains were also solicited prior to the conduct of the interview.
Data Analysis Procedure
Data were analyzed using descriptive statistics such as frequency count,
percent, rank and mean.

Practices on Pesticide Handling, Storage, Application and Disposal
Pesticide handling and storage practices. Table 4 shows the different
practices of handling and storage of pesticide containers by the respondents. Out
of the total 126 respondents, 115 of them separates pesticides from groceries
(rank 1) followed by keeping it away from the reach of children (rank 2). Only 56
of them do not stored pesticides together with any volatile materials to avoid the
chance of explosion or fire.

Pesticide disposal practices. Table 6 indicates the farmers’ disposal
practices of empty pesticide containers. Majority of the farmers buried their
empty pesticide containers on the ground near their houses at a depth of 1-2
meters (ranked 1). Some farmers reported that they burned the containers (rank
2); left the containers in the field (rank 3), and few threw it away in the garbage or
anywhere else. The practices indicate that some farmers are less cautious on the
effects pesticide in the environment.

Symptoms Associated with Mishandling Pesticides
The respondents reported that they had experienced dermal symptoms
brought about by the mishandling of pesticides (Table 9). These symptoms
include skin rashes, redness of skin, and blackening of toe nails. Some also
experienced respiratory problem like coughing and shortness of breath.
In terms of neurological problems, it was reported that they experienced
headaches (rank 1) and fatigue (rank 2). Gastrointestinal problem was exhibited
by vomiting and salivation. There were also reports that some farmers had
ophthalmic problems like itching of the eyes and blurred vision. Few famers
admitted that they suffered abdominal pain after spraying pesticides.

Knowledge on the Environmental and Health Hazards of Pesticide Use
Table 10 summarizes the responses of the respondents on environmental
and health hazards associated with pesticide use.
Hazards on soil. Majority or 63 percent of the respondents agreed that
pesticide causes soil’s acidification, compaction and decreased quality brought
about by continuous use of pesticide. Only 37 percent of the farmers had no idea
about the hazardous effect of pesticides. This shows that many of them are
aware of the ill-effects of pesticides on soil.

14. 13
Hazards on air. Majority (70 percent) of the respondents were
knowledgeable on the pesticide hazards on air like pollution, acid rain build-up,
etc. Few (30 percent) had no idea at all.
Hazards on water. Majority or 63 percent of the respondents agreed that
continuous use of pesticide will contaminate bodies of water responsible for
pollution, affects ground water through leaching, etc. Thirty-seven percent
disagreed to the idea on the hazardous effect of pesticides on water.
Hazards on humans and living organisms. Majority or 65 percent of the
respondents affirmed that continuous use of pesticide could kill human and other
non-target living organisms. It also creates pest resistance. Only 35 percent had
no idea on the hazards posed on humans and other living organisms.

CONCLUSIONS
1. Farmers were in their middle age, had secondary education, and married.
They were tenant-farmers for 30 years farming with 1 hectare with an
average production of 35 cavans. They also undergone seminars on rice
farming but had limited knowledge on the proper handling and application
of pesticides.
2. All the farmers used insecticides to control pests in rice.
3. Farmers sprayed pesticides using knapsack sprayer, wore protective
clothing, stored pesticide in safe places, and buried empty containers near
their houses.
4. Farmers had knowledge on the proper use of pesticides like handling,
storage, application, and disposal of empty containers.
5. Farmers got the knowledge and information on the proper use of
pesticides from the Agricultural Technologists of LGU-Ibajay.
6. Several symptoms were exhibited by farmers’ exposure to pesticides such
as vomiting, itching of eyes and abdominal pains.
7. Farmers were knowledgeable about the ill effects of pesticides on soils, air
and water including on humans and other living organisms.

17. 16
RECOMMENDATIONS
1. Farmers should be given continuous follow-up on training or seminars on
the proper use of pesticides.
2. Technical assistance through the conduct of training and seminars on
organic farming or Integrated Pest management (IPM) should be given to
farmers to minimize the use of pesticides.
3. Information, Education and Communication (IEC) materials such as
videos, leaflets, flyers, comics, brochures should be made available to
farmers emphasizing the proper use of pesticides for environment and
health protection.
