Chester, WG

Effective Corn Protection: Choosing Chester, WG

When corn crops reach the 3–10 leaf stage, weed control becomes a critical operational phase. The systemic herbicide Chester, WG, based on nicosulfuron (a sulfonylurea group active ingredient), is a proven solution for agronomists managing both annual and perennial grasses, as well as several broadleaf weeds.

Key Application Scenarios

This product by China Chemical Industrial and Research Co. Ltd is essential when fields are infested with aggressive weeds that can severely impact yield: quackgrass, barnyard grass, green foxtail, pigweed, field mustard, and common ragweed. Due to its selective action, the herbicide works effectively within the crop, halting weed growth within hours of foliar absorption.

Practical Application Guidelines

• Crop Stage: Ideally applied when corn is in the 3–10 leaf stage.
• Dosage: The standard rate is 0.05–0.07 kg/ha. This is sufficient for a single treatment, which is the maximum allowed per season.
• Formulation: Water-dispersible granules (WG) dissolve easily, do not foam, and ensure uniform distribution in the spray tank.

The systemic mechanism allows the active ingredient to move rapidly through the target weed, reaching the root system of quackgrass and preventing regrowth. As Chester is classified as a Hazard Class 3 substance, standard protective equipment during spraying is mandatory.
