The study examined the effects of herbicides on crop production and environment in Makurdi Local Government Area of
Benue State. Simple random sampling technique was adopted in collecting data. Data were collected through primary and
secondary sources. Primary source was by survey using structured questionnaire administered on 80 respondents (farmers
that used herbicides) selected randomly from four council wards; secondary data were collected from books, journals,
proceedings and documents. Data collected were analyzed through descriptive statistics. Results revealed that 75.0% of the
respondents applied herbicides in the morning, 110.0% used non-selective herbicides, 100% had fatigue while applying
herbicides, 100% read the instruction rebel of the herbicides before applying it, 82.5% applied herbicides facing the direction
