Nukoil, MD

Technological Edge: The Oil Dispersion Advantage

The core efficacy of the «Nukoil, MD» herbicide lies in its formulation: Oil Dispersion (OD). Unlike traditional emulsion concentrates or wettable powders, the OD formulation provides superior adhesion to the leaf surface. The active ingredient, Nicosulfuron, is encapsulated within an oil matrix, which allows it to penetrate the cuticular wax layer of weeds effectively—even under low humidity or heat-stress conditions.

Mechanism of Action: ALS Inhibition

Nicosulfuron is a potent sulfonylurea herbicide. It works by inhibiting the acetolactate synthase (ALS) enzyme, which is responsible for the biosynthesis of essential branched-chain amino acids (valine, leucine, and isoleucine). By blocking this pathway, the herbicide effectively shuts down cell division at the plant's growing points. In practice, this stops weed competition for moisture and nutrients almost immediately, providing a critical buffer for the corn crop.

Selective Control and Systemic Activity

«Nukoil, MD» is designed for selective weed control in corn, targeting both grasses and broadleaf species, including Quackgrass, Amaranth, Wild Mustard, Shepherd’s Purse, Common Chickweed, Barnyard Grass, and Yellow Foxtail. Due to high metabolic selectivity, corn plants safely break down the active ingredient, ensuring crop safety when applied as a post-emergence herbicide.

• Systemic Translocation: Moves through the xylem and phloem, ensuring control of both leaf mass and the root system, which is vital for perennial grasses.
• Dosage Flexibility: Application rate of 0.5–1.25 L/ha allows for precise adjustment based on the weed spectrum and density.
• Manufacturing Standards: Produced in Chile under strict Nufarm Australia Ltd guidelines, ensuring consistent formulation quality.

As a systemic herbicide, it is best applied once the crop is established to clean the field of early-season competition, setting the stage for optimal yields.
