DILYAR, WG

Systemic Weed Control with DILYAR, WG

DILYAR, WG, manufactured by Lier Chemical (Sichuan, China), is a selective post-emergence herbicide designed to protect rapeseed and cabbage crops from hard-to-control broadleaf weeds. By utilizing Clopyralid, a highly effective systemic active ingredient, the product moves rapidly through the plant vascular system, targeting both the foliage and the root system of stubborn perennial weeds.

Why DILYAR, WG stands out

• Targeted Efficacy: The herbicide is exceptionally effective against members of the Asteraceae, Leguminosae, and Polygonaceae families. It provides definitive control over invasive species such as Canada thistle (Cirsium arvense), common ragweed (Ambrosia artemisiifolia), cornflower, and various knotweeds.
• Deep Systemic Action: Unlike contact herbicides that only burn the surface, DILYAR travels to the roots, preventing regrowth—a critical advantage for field management.
• Superior Formulation: The Water-Dispersible Granules (WG) ensure easy measurement, rapid dissolution, and enhanced leaf coverage, which improves the uptake of the active ingredient compared to traditional powder formulations.

Application and Field Performance

As a selective post-emergence herbicide, DILYAR, WG is best applied in a single treatment during the active growth phase of the weeds. The application rate ranges from 0.1 to 0.3 kg/ha, depending on weed density. Its selectivity ensures that the main crop remains unharmed, avoiding the growth setbacks often associated with less precise chemicals.

Pros: Excellent control of deep-rooted perennials and high crop safety. Cons: It does not control grass weeds, meaning it should be used alongside a graminicide if the field has a mixed infestation.

This product is an optimal choice for commercial growers looking for a clean, efficient solution for managing broadleaf weeds while maintaining high yields in sensitive crops like oilseed rape and cabbage.
