Overview
About this product
Bastion Trio has three active substances in one seed treatment: difenoconazole 25 g/L, cyproconazole 3 g/L and fludioxonil 25 g/L. The product combines systemic and contact action.
Fludioxonil acts by contact, penetrates the seed tissue locally, spreads into the soil around the seed and disrupts osmotic signal transduction in fungal cells. Winter wheat and spring barley seed is treated before sowing at 1.5–2.0 l/t against fusarium and helminthosporium root rots, smuts and seed moulds.
Working solution 10 l/t. Pack size 10 l.
