A post-emergence systemic herbicide against annual broadleaf and grass weeds in corn crops

Advantages

  • The combination of two active ingredients with different modes of action (ALS and HPPD inhibition) provides a broad spectrum of control of both grass and broadleaf weeds in a single treatment.
  • Effective control of overgrown and hard-to-control weeds thanks to topramezone.
  • The dual mode of action reduces the risk of weeds developing resistance to herbicides.
  • Wide application window — from the 2- to the 8-leaf stage of corn.

Characteristics

Nicosulfuron, 60 g/l + Topramezone, 20 g/l
Chemical group
sulfonylurea derivatives + pyrazolones (HPPD inhibitors)
Formulation
oil dispersion (OD)
WHO classification
Class III

Recommendations for use

Application features
Spraying of corn crops from the 2- to the 8-leaf stage of the crop inclusive. Treatment is carried out in the morning (before 10:00) or in the evening (18:00–22:00), at an air temperature not exceeding +25 °C and a wind speed not exceeding 3 m/s (fine-droplet spraying) or 4 m/s (coarse-droplet spraying).
Compatibility
Compatible with other products in tank mixes; a miscibility test is recommended before use.
Working solution pH requirements
from 5 to 9
Application precautions
Do not allow the product to enter water bodies; observe application restrictions in water protection zones.
Working solution consumption rate
200–300 l/ha

Mechanism of action

Nicosulfuron inhibits the enzyme acetolactate synthase (ALS), blocking amino acid synthesis in weed cells. Topramezone inhibits the enzyme hydroxyphenylpyruvate dioxygenase (HPPD), disrupting pigment synthesis and photosynthesis. The combination of the two modes of action causes bleaching, growth arrest and rapid death of weeds within a few days after treatment.
