Treating seed at small seed company Bidasem

In the seed processing plant at Bidasem, a seed treatment machine coats maize seed with a mixture that includes insecticide and fungicide to protect it from damage in storage or in the ground, and a bright pink dye to show that it has been treated, and should not be used for human consumption.


Bidasem is a small seed company based in the city of Celaya in the central Mexican plains region known as the Bajío. It produces approximately 10,000 bags of maize seed a year, each holding 22.5kg, as well as producing wheat and oat seed and marketing seed of other crops. Despite their small size, Bidasem and similar companies play an important role in reaching small farmers with improved seed that offers them better livelihoods. “Our aim is to provide farmers with quality seed at accessible prices, that is adapted to the conditions we have here in the Bajío, says director general María Esther Rivas. It’s a great satisfaction, when farmers achieve the yields they need.”


“Without CIMMYT, we couldn’t exist,” says Rivas. She sells four different maize hybrids, all formed from freely-available CIMMYT parent lines. “Really the most important thing is to produce your own hybrids, and for us it wouldn’t be possible if we didn’t have the germplasm from CIMMYT. What we’re currently producing is 100% CIMMYT.” The relationship between Bidasem and CIMMYT is now deepening through participation in the MasAgro initiative, which includes training courses for seed companies and collaborative trials to evaluate the best seed.
