Main advantages
About this product
Belkar Flex — a post-emergence herbicide for winter rapeseed in the form of an emulsifiable concentrate that combines three active substances from the group of synthetic auxins: halauxifen-methyl (Arylex active) 10 g/l, picloram 48 g/l and aminopyralid 32 g/l. It controls a wide spectrum of annual dicotyledonous weeds — cleavers, chamomile, poppy, scentless mayweed and sunflower volunteers — and provides prolonged action thanks to its soil activity. It is applied once in autumn at a rate of 0,25 l/ha from the 2 leaf stage (BBCH 12) to 8 leaves (BBCH 18).
