The Tanzania Official Seed Certification Institute (TOSCI) has urged farmers across the country to purchase only certified seeds bearing official verification labels to safeguard themselves against counterfeit products that undermine agricultural productivity and incomes.
Speaking to journalists at the 2026 Nanenane International Agricultural Exhibition at the Dr. John Samuel Malecela Grounds in Dodoma, TOSCI Director General Nyasebwa Chimagu said certified seeds remain the foundation of higher crop yields and sustainable agricultural growth.
He stressed that every seed package sold to farmers must carry a TOSCI certification label, which serves as proof that the seed has undergone inspection, testing and approval in accordance with national quality standards.
"We want to remind farmers that every seed package must have a TOSCI certification label. If it does not have one, they should not buy it. That is the most reliable way to protect themselves from counterfeit seeds," he said.
Mr Chimagu noted that the government has introduced a digital verification system that allows farmers to confirm the authenticity of seeds using their mobile phones before planting, helping them identify genuine products and avoid potential losses.
He warned that the use of uncertified seeds often leads to poor crop performance, reduced yields and financial setbacks, particularly for smallholder farmers who depend on agriculture for their livelihoods.
According to him, TOSCI is using this year's Nanenane exhibition to raise awareness about the importance of quality seeds, proper handling and transportation practices, and compliance with regulations governing the seed industry.
He said studies indicate that farmers who use certified seeds alongside recommended agronomic practices can achieve harvests ranging between five and 10 tonnes per hectare, depending on the crop and prevailing farming conditions.
Mr Chimagu encouraged farmers to take advantage of the exhibition to learn about improved seed varieties and modern agricultural technologies that can boost productivity during the 2026/27 farming season.
"Nanenane serves as a learning platform for farmers. We encourage them to use this opportunity to gain knowledge on quality seeds and modern farming technologies that can help increase productivity and strengthen the agricultural sector," he said.
Agriculture remains the backbone of Tanzania's economy, employing the majority of the population and contributing significantly to food security, exports and industrial development.
