- NOVA HALO-MET is a herbicide combination used for broad-spectrum weed control in sugarcane, particularly targeting Cyperus rotundus (nutgrass) and other broadleaf and narrow-leaf weeds. It works by interfering with essential metabolic processes in the weeds, leading to their death.
Key Uses:
- Sugarcane: Effective for controlling weeds like Cyperus rotundus and other common weeds in sugarcane fields.
- Broad-spectrum weed control: Targets a wide range of weed species, including Cyperus rotundus by nuts, and both broadleaf and narrow-leaf weeds.
- Safe to the crop: Designed to be safe for the sugarcane crop itself, ensuring minimal harm to the main plant.
- Higher tillers: Can contribute to increased tillering (the formation of new shoots) in sugarcane.
Mechanism of Action:
- Halosulfuron methyl: Inhibits acetolactate synthase (ALS), an enzyme crucial for the synthesis of branched-chain amino acids, essential for plant growth. This leads to a cessation of cell division and plant growth in both roots and shoots.
- Metribuzin: Inhibits photosynthesis, disrupting the process by which plants convert light energy into chemical energy.
Application:
- Post-emergence: Typically applied after the weeds have emerged, targeting actively growing weeds.
- Specific timing: Application is often recommended during the 3-5 leaf stage of weed development.
- Broad spectrum control: Controls a wide range of weeds, including Cyperus rotundus.
