Bayer launches technologies at the 2025 Brazilian Soybean Congress

Bayer is presenting four new products in its integrated portfolio during the 2025 Brazilian Soybean Congress. The launches focus on managing seeds, weeds, pests, and diseases in soybeans.

To control diseases such as Asian rust, target spot and rot, the company announces the Fox Ultra fungicide. This is a mesostemic and systemic product composed of prothioconazole, impirfluxam, and trifloxystrobin, active ingredients from the pyrazolecarboxamide, triazolinthione, and strobilurin chemical groups. The Fox family of fungicides has been Bayer's leading player in the segment for 12 years, explains Guilherme Hungueria (pictured), the company's crop marketing manager.

Fox Ultra's mechanisms of action include inhibiting mitochondrial respiration complex II, inhibiting sterol biosynthesis, and inhibiting C14 demethylation, acting at different stages of the infectious process. According to the company, it should always be used as a preventative measure against the onset of diseases, thus ensuring the greatest potential for fungal control.

Bayer reports that the product led the results of the product evaluation network in the 2024/25 harvest, the year of its pre-launch.

Weeds

For the control of resistant weeds, Bayer launches the Convintro Duo herbicideThe product combines the active ingredients diflufenicam—a first in Brazil—and metribuzim. One of the reasons for the launch is the presence of glyphosate-resistant weeds in the field, explains Hungueria.

Convintro Duo is a selective herbicide from the anilides and triazinones chemical group. It should be applied pre-planting soybean crops and pre-emergence of weeds. Its pre-emergent effect lasts up to 35 days, with an emphasis on weed control. crow's foot grass and caruru. Currently, there is a record against Amaranthus palmeri, Amaranthus viridis, bidens pilosa, Digitaria horizontalis, Digitaria insularis e Eleusine indica.

Seeds

The Guardião and Guardião+ packages combine seed treatment (ST) solutions. The solution protects the plant up to the V4/V5 stage, approximately 30 days after sowing. The packages include control against pests, early diseases, and nematodes. The treatment now incorporates the fungicide Evergol (penflufen), Bayer's first carboxamide, which allows for active ingredient rotation and strengthens defense against soil-borne fungi.

Bayer also highlights advances in its Intacta2 Xtend biotechnology, which has achieved yields above 100 bags per hectare. The company is preparing to launch the third generation of Intacta soybeans and is already testing the fourth, focusing on increased productivity and sustainability.
