Sheldon, KS

Mechanism of Action and Selectivity

Sheldon, SC is a systemic post-emergence herbicide containing nicosulfuron, engineered for the comprehensive control of weeds in maize crops. As a member of the sulfonylurea family, the active ingredient targets the acetolactate synthase (ALS) enzyme. By inhibiting this enzyme, the herbicide halts cell division at growth points, effectively ceasing weed competition for nutrients and moisture within hours of application.

Control Spectrum

The product provides robust performance against a wide range of problematic species:

• Grasses: couch grass (Elymus repens), barnyard grass (Echinochloa crus-galli).
• Broadleaf weeds: lamb's quarters, pigweed, field mustard, shepherd's purse, common chickweed, common ragweed.

Technical Application Details

The suspension concentrate formulation ensures superior spray coverage and adhesion to the waxy leaf surfaces of weeds. Sheldon is a highly selective herbicide; maize plants possess the metabolic capacity to rapidly neutralize the active ingredient, ensuring crop safety. The application rate of 1–1.25 L/ha provides maximum biological efficacy through a single post-emergence pass. Due to the high concentration of the active substance, the product is restricted to one application per growing season.

The manufacturing process integrates the expertise of Shanghai Bioagriland Crop Care (China) with the production capabilities of the Agrochemical Factory in Cherkasy (Ukraine), ensuring that the formulation meets rigorous agricultural standards for efficacy and stability.
