Professional weed control in corn fields: insights on using "Priority"

When perennial weeds like couch grass or green foxtail start threatening your corn yield, you need a reliable solution. I rely on "Priority," a systemic herbicide manufactured by Sunrise Chemicals Co. Ltd., Shanghai. Based on nicosulfuron (sulfonylurea derivatives), this herbicide has become my go-to choice for post-emergence application.

Operational experience

The product comes as a suspension concentrate, making it easy to mix and apply. With a dosage of 1.0 to 2.0 L/ha, it shows excellent selectivity: the corn remains unharmed while target weeds receive a lethal dose of the active ingredient. As a selective post-emergence herbicide, it works best when applied directly to the leaves during the active growth stage of the weeds.

• Broad-spectrum control: Highly effective against creeping bentgrass (couch grass), common lambsquarters, green foxtail, and Johnsongrass.
• Flexible timing: With a pre-harvest interval of only 1 day, it provides the necessary agility for your harvesting schedule.
• Application standards: Classified as a Class 3 hazard, it requires standard protective measures for the operator during spraying operations.

From my perspective, "Priority" is a practical choice for those who value efficiency. By using nicosulfuron correctly according to the crop stage, I have consistently achieved clean fields without crop phytotoxicity. It is a workhorse herbicide that delivers predictable results at a reasonable cost, making it ideal for large-scale corn production.
