Description

Clopyralid is a highly effective, systemic herbicide belonging to the pyridine carboxylic acid chemical class. Its primary value lies in its exceptional selectivity and potency against a wide spectrum of broadleaf weeds, particularly those in the Asteraceae, Fabaceae, and Solanaceae families. This product is essential for agricultural professionals, turf managers, and industrial vegetation control specialists seeking reliable, long-lasting weed management solutions in crops like cereals, oilseed rape, and pastures, as well as in non-crop areas.

Application

• Selective Weed Control in Cereal Crops: Post-emergence control of key broadleaf weeds such as thistles, mayweed, and cleavers in wheat, barley, and oats.
• Oilseed Rape Protection: Management of problematic weeds including volunteer potatoes and various mustard species in oilseed rape cultivation.
• Pasture and Rangeland Management: Effective control of invasive weeds like knapweed and clover in grasslands to improve forage quality and quantity.
• Turf and Lawn Care: Used in professional turf management for controlling weeds like plantain and dandelion in lawns, golf courses, and sports fields.
• Industrial Vegetation Management (IVM): Control of brush and broadleaf weeds along rights-of-way, railways, utility sites, and industrial perimeters.
• Forestry and Silviculture: Site preparation and conifer release programs to manage competing vegetation in tree plantations.
