Perun

Perun is a selective, soil-applied herbicide from DEFENDA formulated as a suspension concentrate containing 500 g/l of the triazine active prometryn. It controls annual broadleaf weeds, including species tolerant to other herbicides, in sunflower, soybean, potato, carrot and pea crops. Absorbed through roots and foliage, prometryn blocks photosynthesis in emerging weeds, which die within five to seven days. Apply pre-emergence or early post-emergence at 2.0–5.0 litres per hectare.
