Weed resistance, herbicides that no longer work as well as they used to, control costs that only keep rising…
These are some of the challenges that soybean, corn, cotton, and other major crop producers will face in Brazil in 2026, a year in which climatic conditions are expected to further favor the development of weeds in the fields.
But even with this scenario, some producers and researchers have discovered how to keep their crops clean while spending far less than average, while others continue to increase the doses and the number of applications without solving the problem.
One of the people behind these discoveries is Dr. Gizelly Santos, a producer in Mato Grosso do Sul and researcher specializing in weed management, who, over more than a decade of work in the field, has identified the main mistakes that cause producers to spend more than necessary on herbicides.
"The problem isn't the herbicide. The problem is how most people have learned to use it. When you understand weed behavior and adjust the timing, dosage, and application sequence, you can control them better while spending less. I've seen producers go from..." R$ 450 per hectare for less than R$ 250"keeping the fields clean throughout the entire growing season."
The method that Gizelly developed has already been applied in +18 million hectares by producers and consultants from various regions of the country, with consistent results in controlling weeds such as goosegrass, sourgrass, horseweed, amaranth, and morning glory.
You can also learn these techniques for free!
Between January 27th and 29th, Gizelly will be hosting the online event "The Truth About Herbicides," a free mini-course with 3 live classes on YouTube where she will show what nobody talks about regarding weed management.
It will be an open event where, throughout the 3 live classes on YouTube, topics such as the following will be covered:
Why are weeds becoming increasingly difficult to control, and what can you do to change that in your crops?
→ The most common management mistakes that cause producers to spend twice as much as necessary on herbicides;
→ The method that allows keeping crops clean while using up to 50% less, already applied to millions of hectares;
→ How to start using these management practices as early as the 2026 harvest and see results this season;
Even though your last harvests were marked by high herbicide costs and lower-than-expected control results, it's still possible to turn things around and start saving as early as the 2026 harvest.
How can I participate in the event and learn these techniques at no cost?
To gain access to the classes, you need to click here and complete a simple registration, which takes less than a minute.
Then, simply join the event's WhatsApp group for announcements, where you'll find links to the classes and supporting materials in PDF format, and wait for the evening of January 27th, as Class 1 starts at 7:30 PM (Brasilia time), live on YouTube.
This is an opportunity for all agricultural professionals who deal with weed control.
Whether you are a producer, farm manager, agronomist, consultant, agricultural technician, or a professional who works with input recommendations.
