Sonhus, WG, herbicide

Systemic control of tough weeds

"Sonchus, WG" by Nertus is a highly concentrated herbicide based on clopyralid. The technical efficiency of the product lies in its systemic mechanism: the active substance mimics auxins, triggering a metabolic crash in weed tissues. Unlike contact herbicides, Sonchus absorbs through the leaf surface into meristematic zones, effectively blocking root growth, which is critical for controlling perennial rhizome weeds.

Technical advantages

• High Selectivity: Designed as a selective herbicide, it ensures crop safety for cereals, corn, and winter rapeseed when following application protocols.
• WG Formulation: Water-dispersible granules ensure rapid mixing in the tank, preventing sediment formation or nozzle clogging during operation.
• Targeting Tough Weeds: Clopyralid is the industry gold standard for controlling creeping thistle, sow thistle, and mayweed. The herbicide destroys weeds from within, effectively reaching the root system.

Application Guide

For optimal results, apply as a post-emergence herbicide during the active growth phase of weeds. The application rate ranges from 0.5 to 1.0 l/ha, depending on weed pressure and the crop type. A key technical feature is the single-application requirement: due to the high activity of the active ingredient, one spray is sufficient to suppress sensitive weed species for the entire growing season. Classified as hazard class 3, Sonchus requires standard safety precautions when handling agrochemicals.
