DEFENDA Ultralin

Ultralin is a combined, locally-systemic water-dispersible granule fungicide from DEFENDA that pairs azoxystrobin (250 g/kg), a strobilurin, with cymoxanil (300 g/kg). It delivers both protective and curative action against a complex of fungal diseases on sunflower and soybean. Azoxystrobin blocks spore germination by inhibiting mitochondrial respiration, while cymoxanil penetrates leaves and stems quickly and moves upward, compensating for uneven spraying. Apply at 0.3–0.5 kg/ha during the growing season.
