Application; To prevent rapeseed, corn, grass and other annual broadleaf weeds in field and deep-rooted perennial broadleaf weeds ( Asteraceae and leguminous weeds )

Clopyralid Mode of action:
Selective systemic herbicide, absorbed by the leaves roots, with translocation both acropetally basipetally, accumulation in meristematic tissue, exhibits an auxin-type reaction, acts on cell elongation respiration.
Crops: Sugar beet, fodder beet, maize, and grassland

Clopyralid Control:
Many annual and perennial broad-leaved weeds of the families Polygonaceae, Compositae, Leguminosae, and Umbelliferae.
Provides particularly good control of creeping thistle (Cirsium arvense), perennial sow-thistle, coltsfoot, mayweeds, and Polygonum spp.

Use of Clopyralid 95% TC:
Post-emergence control of many annual and perennial broad-leaved weeds of the families Polygonaceae, Compositae, Leguminosae, and Umbelliferae, in sugar beet, fodder beet, oilseed rape, maize, cereals, brassicas, onions, leeks, strawberries and flax (at 70-300 g a. E. /ha), and in grassland and non-crop land (at 300-560 g a. E. /ha). Provides particularly good control of creeping thistle (Cirsium arvense), perennial sow-thistle, coltsfoot, mayweeds, and Polygonum spp
