About this product
Nopasaran is a post-emergence herbicide for Clearfield oilseed rape, combining metazachlor (375 g/L) and imazamox (25 g/L) in a suspension concentrate. The two active ingredients act systemically through leaves and roots, disrupting amino-acid synthesis to control annual and perennial broadleaf and grass weeds, including cereal volunteers. It is applied once from the 2- to 6-leaf crop stage, timed to early weed growth, only on Clearfield-tolerant hybrids and always with the Metolat adjuvant.
