Carboxamides: Preventive Protection in Crop Cultivation

Carboxamides, classified as SDHI Fungicides, play a fundamental role in disease management in various crops such as soybeans, corn, and wheat, according to Wesler Marcelino, market developer at Biotrop Biological Solutions. This chemical group acts by inhibiting the succinate dehydrogenase enzyme (SDH), essential for the respiratory process of fungi, which blocks oxygen utilization and, consequently, energy production, leading to the pathogen's death. The main function of carboxamides is preventive, forming a kind of protective barrier that prevents the penetration and development of fungal infections in plants. This characteristic makes the use of these products strategic during periods of higher disease pressure, ensuring prolonged protection and reduction of crop losses. In practice, carboxamides are frequently applied in mixtures with other fungicides, such as strobilurins and triazoles, expanding the spectrum of action and delaying pathogen resistance.
