Mr Vincent Frimpong-Manu, Country Manager of Solidaridad, a Dutch International Development Organisation involved in the promotion of sustainable agriculture, cautioned that misuse of such agro-chemicals could be counterproductive.
It was only by applying the right agro-chemical and in the right quantities that increased crop production and quality would be assured.
Mr Frimpong-Manu made the call in an interview with the Ghana News Agency at New Edubiase in the Adansi South District.
He spoke of the need to do more to support farmers with appropriate farming technologies to boost crop yield and returns and transform their livelihoods.
It was to help achieve this that his organisation was assisting smallholder producers, both organised and cooperatives, through training to enable them to market certified agricultural products such as cocoa, coffee, fruits and palm oil, he said.
He said Solidaridad, in partnership with Independent Certification and Traceable Organization (UTZ), was training over 50,000 cocoa farmers across the country.
This is to build their capacity in the cocoa value chain to promote efficient and good agricultural practices which would lead to international certification standards.
