Assessment of Safety Measures and Costs Effect of Herbicide Usage among farmers in Mokwa Local Government Area, Niger State

Weed is one of the most important constraints that limit food production. Checking weeds with herbicides could be harmful if safety precautions are not followed by users. This study assessed the use of safety practices and costs associated with herbicide use among farmers in Mokwa Local Government Area of Niger State, Nigeria. Multistage sampling technique were used to select 160 respondents that were interviewed. Data were analyzed using descriptive statistics and costs addition. Results revealed that contact (Paraquat), selective (2,4-Dimethylamine), non-selective systemic (Glyphosates) and mixture of (2-4-Dimethylamine) and (Glyphosate or Paraquat) were used by respondents to control weeds. The rates of herbicide application ranged from 2.0 and 3.8 litres per hectare with a mean rate of 3.1 litres per hectare. The mean index of Safety practices was 0.68, an indication of high use of safety practices. Use of hand gloves, face masks, eye glasses and rain boots was low. Herbicide containers and left over herbicide solutions were not properly disposed by a larger proportion of respondents. Costs of herbicide usage for major crops cultivated by respondents varies from N4,859 to N7,025 per hectare. Implementation of extension programmes on safety measures in usage of herbicides and sensitization on farmers on protective tools usage were recommended.
