Knowledge and Practices of Herbicide Use Among Farmers is a well-researched topic, it can be used as a guide or framework for your Academic Research/


This study was designed to investigate the
knowledge and practices of herbicides use among
farmers in Edo State, Nigeria. Multistage sampling
technique was used to select one hundred and
twenty (120) respondents. The instrument for data
collection was interview schedule designed by the
researchers. The data obtained were analysed
using mean statistic and standard deviation and
presentation in percentage. The findings of this
study showed that the knowledge of the respondents
on herbicide use was high as 95.8% of farmers’
stored herbicides away from food and admitted that
herbicide could harm the environment as well as
the consumers (95.8%). The theoretical practices
of respondents were encouraging as opposed to the
actual practices where farmers fell short of the
ideal. Best practice used by respondents were
washing of hands after using herbicides or their
containers ( = 2.91), storage of herbicides in
locked cabinets ( = 2.82) and cleaning and
rinsing sprayers after use ( = 2.69), Glyphosate
(85.8%) was the most used herbicide for weed
control and cassava (90.0%) cultivated crop in the
study area. Conclusions and recommendations
were made.


Chemical herbicides have contributed to the
protection of crop, human, and animal health for
over a half century. However, management of
herbicides in developing countries is often
inadequate due to lack of available resources. This
is particularly true for countries where regulations
are not strictly implemented and farmers’
knowledge of safe handling is often inadequate [1].
Many African and other developing countries
suffer from weak import controls, lack of training
on appropriate herbicide use, inappropriate
donations and aggressive sales practices, poor
storage and stock management, pressure to
stockpile for unforeseen emergencies, and a lack of
safe destruction technologies [2]. Though a good
number of farmers are disposed to the use of
herbicides, many are unaware of herbicide types,
level of poisoning, safety precautions and potential
hazards on health and environment [3].
Over the past ten years, the amount and number of
different herbicides have increased significantly.
This have led to growing concern about the
possible adverse effect on human health such as
cancer, birth defects, reproductive problems,
tumours, and damage of liver, kidney and neural
organs [4]. Also, the environment is affected as
abuse of herbicides could lead to contamination of
soil, water, and air thereby damaging the
surrounding ecosystem and other living organisms
necessary for maintaining ecological balance, for
example insects, birds, worms, fish, etc.
Most farmers are aware that herbicides are
hazardous; however, there is lack in awareness of
exposure risk. This exposure is further enhanced by
farmers’ practice of washing their sprayers near or
in the irrigation canal. They also use this water
source for washing of hands and feet, clothes, and
to some extent taking a bath. Most herbicides
handlers use backyards or open fields for disposal
purposes while some sell the used herbicides
container or throw them into nearby water [9].
