Starane Premium 330 EC, KE, herbicide

Technology of Systemic Broadleaf Weed Control

Starane Premium 330 EC by Corteva is a high-tech systemic herbicide designed to block growth processes in the most aggressive broadleaf weeds. The formulation is based on fluroxypyr, an active ingredient belonging to the synthetic auxin class. The key engineering feature of the product is its ability to penetrate the leaf tissue instantly and translocate throughout the entire plant, effectively reaching growth points and the root system.

Mechanism of Action and Selectivity

Unlike contact herbicides, Starane Premium acts systemically. Once absorbed, fluroxypyr triggers abnormal cell growth: weeds lose their ability to photosynthesize and sustain themselves within hours of application. For an agronomist, this means immediate elimination of competition from aggressive species such as cleavers, field bindweed, and common lambsquarters.

The composition's high selectivity allows for safe use on a wide range of crops, including wheat, barley, rye, triticale, corn, and onions, with no risk of phytotoxicity. The formulation eliminates the need for complex tank mixes, simplifying field operations.

Practical Application Insights

• Systemic Action: Full penetration into plant tissues within 1 hour, providing excellent rainfastness.
• Application Rates: Depending on the weed spectrum, the application rate ranges from 0.5 to 1.0 L/ha.
• Superior Efficacy: A critical advantage is its ability to control cleavers (Galium aparine) at all developmental stages, a task often challenging for other herbicide classes.

The emulsifiable concentrate formulation ensures high stability of the spray solution, preventing sediment buildup in the sprayer tank and providing uniform coverage of the leaf surface. Starane Premium is a reliable post-emergence insurance tool, requiring only one application per season.
