New technology expands control of soybean diseases.

A new fungicide technology is arriving on the Brazilian market, focusing on the control of Asian soybean rust and other diseases. soyThe solution combines prothioconazole and chlorothalonil in a ready-to-use mixture and was evaluated by researchers and consultants in different producing regions before the start of commercialization in the 2026/27 crop season.

Cortina Gold, from Sipcam Nichino Brasil, was presented at the Eloos Fungi event, which brought together field results obtained by researchers and consultants. According to agronomist Iago Carraschi, from the market development area, the product underwent evaluations by 25 consulting firms.

In studies conducted by the MS Foundation, the fungicide achieved a productivity of 4,800 kilograms per hectare. In Network Trials, it registered almost 4,600 kilograms per hectare and control of 60% of rust. In studies coordinated by the Mato Grosso Foundation, the effectiveness against target spot reached 84%, while the compared treatments ranged between 46% and 80%.

The results presented at the meeting also indicated good performance in controlling powdery mildew, leaf spots, and cercospora leaf spot. In situations of high severity, the indices were above 60% and came close to 90% in certain fields.

“Cortina® Gold is a high-quality formulation solution, composed of a triazole and a high-performance multisite inhibitor for controlling the main soybean diseases. Rapidly absorbed by the plant, it provides high protective, curative, and eradicative efficacy, and is also characterized by a low risk of developing resistance to crop pathogens,” concludes Iago Carraschi.
