2,4-D-Active

Systemic Weed Control: How 2,4-D-Active Works

The core of this plant protection product is the classic active ingredient 2,4-D formulated as an emulsifiable concentrate. This herbicide functions as a synthetic auxin, triggering uncontrolled cell division in dicot weeds, which inevitably leads to tissue deformation and plant necrosis. Its systemic nature allows the product to penetrate the leaf surface and rapidly translocate through the vascular system to the growing points.

Technical Composition Analysis

The emulsifiable concentrate formulation ensures superior wetting capability upon contact with the weed surface. Unlike powder formulations, this emulsion penetrates the cuticle layer more efficiently, which is critical for performance under varying field conditions. The product exhibits high selectivity, targeting susceptible species while leaving cereal crops, such as winter wheat, barley, or maize, unaffected.

Spectrum and Application Tactics

Post-emergence application allows agronomists to treat fields when weeds are actively growing and at their most vulnerable stage. 2,4-D-Active demonstrates high biological efficacy against major broadleaf weeds:

• Thistles: Effective control of Cirsium arvense (creeping thistle).
• Cruciferous weeds: Complete neutralization of Sinapis arvensis, Raphanus raphanistrum, and Capsella bursa-pastoris.
• Other species: Efficient management of Chenopodium album, Amaranthus retroflexus, Polygonum persicaria, and Convolvulus arvensis.

The manufacturer, Sunrise Chemicals Co. Ltd. (Shanghai), ensures formulation stability in compliance with international standards for Class 3 hazard compounds. The primary utility of this product is to ensure crop purity during critical growth phases when resource competition for moisture and nutrients is at its peak.
