CAS NO.: 111991-09-4
Nicosulfuron is a broad spectrum herbicide that controls a wide range of maize weeds, both annual weeds and perennial weeds.
Function Nicosulfuron is an herbicide for maize, and forage maize in particular. It has been in use since the early 1990s. The substance is a systemic selective herbicide, displaying general selectivity. Therefore, this agricultural chemical can make sure that it is effective at killing other plants growing near the maize even those grasses closely related to maize.
Crop | Target | Rate of Use | Application |
Maize field | Annual weed | 40-60 g/ha. | Spray |
Benefit
Selectivity is achieved by maize plants that have the ability to metabolise nicosulfuron into harmless compounds.
Note
This weed control chemical may cause yellow bands on leaves on rare occasions. Research has shown that this symptom is transient and does not affect yield.
