Nicolas herbicide is an oil dispersion (OD) formulation containing the sulfonylurea herbicide Nicosulfuron. It is a selective post-emergence herbicide, used to control annual grass weeds, broad‑leaved weeds and perennials grass weeds such as Sorghum halepense and Agropyron repens in maize.
Active ingredient: Nicosulfuron 40 g/L OD
Mode of action
Nicosulfuron is rapidly absorbed by the foliage and roots of the weed and is translocated through the xylem and phloem towards the meristematic zone. In this zone, Nicosulfuron inhibits acetolactate synthase (ALS), a key enzyme for branched‑chain amino acids synthesis, which results in the cessation of cell division and plant growth.
SAFETY PERIOD (Pre-harvest interval):
