Grazmec – innovation that transforms

Behold, we have come in new times …

What was manual, became automated.

What was traditional, became innovative.

What was bare became mechanized.

We move towards transformation and change, but our love for the countryside remains the same.

Innovation is a tool that motivates and makes possible each process, turning seeds into life, preparing the farmer, ensuring tomorrow.

Our commitment is with the earth! With innovation! With productivity!

We project our way every day, perfecting the most advanced technologies, turning dreams into reality and making a difference in the lives of thousands of farmers, turning their potential into motivation to go further.

How to produces more!

Seed treatment is one of the most important stages in the process of a crop, because if it is not done well at the beginning with quality machines, the farmer will end up having losses at the time of harvest, so a well-treated seed Produces more, and Grazmec for more than 30 years has been researching, designing, testing and marketing machines that reduce seed risk and damage to the maximum.


Grazmec seed treatment machines are pioneers in the use of rubber screws, which protect the seeds against mechanical damage. The entire OnFarm and Industrial line, which uses conveyor screws and homogenizers, are equipped with this system. All Grazmec machines are designed to protect the seed at the time of treatment, so the farmer has a high productivity gain because the treatment is performed on quality machines.


The design of the Grazmec seed treatment machines is designed to avoid as much as possible the excessive movement and crushing of the seed, especially after the treatment is carried out because at this stage the seed becomes more fragile.


The passage of the seed in contact with the screw is carried out in the shortest time, only what is necessary to give an excellent homogenization. Grazmec machine screws have flexible and soft ends, from which they protect the seeds from damage.


Another care and detail that Grazmec dedicates to work are to offer machines that make the exact dosages in places designed to receive the product (liquid and/or powder) so that all the seed is treated in a uniform way.


That is why the seeds treated by the Grazmec machines avoid mechanical damage to the seeds (bruises on the seed), increase the emergence and consequently increase the productivity of the crop.


Grazmec says “Well-treated seed produces more”!

Seed Treatment

Seed treatment as part of modern agriculture in Brazil

Seed treatment is an excellent example of how the seed industry and the agrochemicals industry are innovating, given the future of modern Brazilian agriculture. The industrial treatment of seeds has increased significantly in importance as companies have been working to create new and more productive technologies, especially generated to meet the needs of farmers to combat pests (diseases, insects, nematodes, weeds, among others). The treatment of seeds serves as a means of transporting products aimed at the control of these pests, characterizing itself as one of the most important practices of integrated pest management, helping to increase the production and the yield of the crops.

Seed treatment is an effective tool to combat the negative effects of pests at planting time and thereby help farmers to produce more and better quality while minimizing the negative impact on humans, animals, and the environment.

Definition of seed treatment:

Seed treatment is the application of chemical ingredients and/or biological organisms to the seeds in order to suppress, control or wards off pathogens, insects or pests that attack seeds, seedlings and plants.

Technologies applied to seed, as inoculant, protective agents, and herbicides, micronutrients, growth regulators, seed coatings, dyes, etc. May also be considered seed treatment. The treated seeds are intended exclusively for planting and not related to human or animal feed.
