Assessment of farmers' knowledge and pesticides management in cocoa production in Ghana

The use of pesticides to control pests and diseases has been a measure to increase cocoa productivity in Ghana. However, regular use and indiscriminate application of pesticides have unintended environmental and health risks. This study assesses the types of pesticides used by cocoa farmers in Ghana, sources and knowledge on application rate, frequency of application and factors that could influence farmers' choice of source of pesticides, knowledge on application rate, and frequency of application. Two hundred and forty cocoa farmers from the Dormaa West District of Ghana were interviewed from December 2014 to February 2015 using a pre-tested questionnaire. The results showed that farmers sourced pesticides from agrochemical shops and fellow farmers, with some benefiting from the government of Ghana's "free mass cocoa spraying" program. A majority (51.2%) of the farmers sprayed more than three times per cocoa season. In addition, 35% of the farmers dangerously mixed two or more different pesticides together when spraying. Gender, age, educational level, and income from cocoa farming significantly influenced the choice of source of pesticide while knowledge on pesticides application rate was significantly influenced by educational level of farmers, access to extension services, presence of agrochemical shop, membership of a farm-based organization, and age of a farmer. Frequency of pesticides application was significantly influenced by educational level of farmers, access to extension services, presence of agrochemical shop, membership of the farmer-based organization, knowledge of Ghana COCOBOD recommendation on pesticides application rate, income from cocoa farming, and age of farmers. The majority of the farmers mixed two or more pesticides together during spraying. The limitation of this research is the inability to carry out the survey in other cocoa-growing districts within the study region. There is a need for the training of farmers on the safe use of pesticides by the Ghana COCOBOD to effectively manage pests and diseases and reduce environmental pollution.
