Apriori

Apriori is a post-emergence herbicide for maize combining two active ingredients — nicosulfuron (230 g/kg) and mesotrione (570 g/kg) — formulated as water-dispersible granules. It provides contact-systemic control of annual and perennial broadleaf and grass weeds, with reliable activity on white goosefoot and suppression of common milkweed. Applied once by spraying at the crop's 2–8 leaf stage at 0.2–0.25 kg/ha plus a surfactant, it combines soil and foliar action.
