Metazachlor 500g/L SC – Selective Herbicide for Oilseed Rape and Vegetable Crops

Metazachlor 500g/L SC a chloroacetamide-class herbicide formulated as a suspension concentrate (SC), targeting grass and broadleaf weeds in oilseed rape, cabbage, and other brassica crops. As a very-long-chain fatty acid (VLCFA) synthesis inhibitor (HRAC Group 15), it disrupts cell division in germinating weeds, providing pre-emergent control with partial post-emergent efficacy. Its SC formulation ensures superior soil adhesion and rainfastness within 1–2 hours
