Fungicide resistance advances in Brazil and demands more efficient management solutions

Fungicide resistance is one of the biggest challenges of modern agriculture and often behaves like the repeated use of some human medications: the more frequent, the lower the effectiveness. In the field, when the same active ingredient is constantly used, the organism or, in this case, the fungus, develops ways to defend itself. Over time, it stops responding to the treatment, reducing the effectiveness of control and compromising the health of the crop. “In agriculture, the selection pressure favors the survival of the less sensitive fungi. They multiply and transmit this characteristic to the next generations. The result is a resistant population and increasingly difficult control. That is why monitoring, alternating, and rotating fungicides is essential to preserve the effectiveness of the molecules and ensure sustainable productivity,” explains Paulo Moraes Gonçalves, Market Development Specialist at Ourofino Agrociência. Fungicide resistance is seen globally as one of the ...
