Nelson c.s.

Systemic weed control: pre-emergence soil protection

«Nelson C.s.» by China Chemical Industrial and Research Co. Ltd. is a specialized tool for farmers aiming to secure clean fields before crop emergence. Based on prometryn, this herbicide acts as a reliable soil barrier, providing a robust shield against most annual grass and broad-leaved weeds.

Field Application Scenarios

The primary task of this herbicide is to establish a "protective screen" in the topsoil layer. It is most effective when applied immediately after sowing, before the sprouts of carrots, coriander, or peas emerge. Due to its selective action, crops remain unharmed, while weeds absorb the active ingredient through their root systems during germination, leading to their early elimination.

• Sunflower and Corn: The product is often chosen to suppress the first "flush" of weeds, preventing competition for moisture and nutrients during the critical initial growth phase.
• Carrots and Coriander: Essential for these crops, as their seedlings are often overwhelmed by aggressive weeds, making late-stage control difficult.
• Peas and Potatoes: Significantly reduces the need for manual or mechanical weeding early in the season.

The suspension concentrate formulation ensures stable performance in the sprayer tank, provided proper agitation is maintained. It is important to note that maximum effectiveness is achieved with sufficient soil moisture, as the herbicide enters the weed root zone via soil water.

Practical Recommendations

As «Nelson C.s.» is a systemic herbicide (Hazard Class 3) with a single-application limit per season, it requires strict adherence to usage guidelines. By applying this herbicide pre-emergence, agronomists achieve a "clean start," simplifying subsequent field management and maximizing yield potential by eliminating early-season weed competition.
