Mechanism of Action and Selectivity

"Shpaga" by Shandong Weifang Rainbow is a systemic herbicide based on dicamba, functioning as an auxin-like growth regulator. Unlike soil-applied herbicides, this product is absorbed primarily through the leaf surface. Dicamba rapidly translocates to the meristematic tissues of the plant, causing uncontrolled cell division and structural deformation of stems and leaves, which inevitably leads to the death of broad-leaved weeds.

Technical Specifications

The product is formulated as a soluble concentrate. This chemical design ensures the stability of the spray mixture and a high absorption rate upon post-emergence application. Due to its selective properties, the herbicide allows for the efficient cleaning of cereal crops (wheat, barley, oats, millet) from complex broad-leaved weeds, including perennial species, without damaging the crops themselves.

Application Guidelines

• Target Efficiency: Controls a wide spectrum of annual and perennial broad-leaved weeds.
• Application Rates: Recommended dosage is 0.15–0.3 L/ha, depending on the weed infestation level.
• Usage Details: Post-emergence application (insurance herbicide) is performed once per season.

It is important to note that "Shpaga" falls under Hazard Class 2, requiring strict adherence to safety protocols during the preparation of tank mixes and operation of spraying equipment. The systemic nature of the product ensures protection not only for the parts of the weed contacted by the spray but also for areas currently in active growth stages.
