Application

Picolinafen is primarily used as a selective herbicide for pre-emergence and early post-emergence control of broadleaf weeds in cereal crops. It inhibits carotenoid biosynthesis, leading to chlorophyll degradation and plant death. Researchers utilize Picolinafen to study its environmental fate, including soil persistence and degradation pathways. Additionally, it serves as a reference standard in analytical chemistry for residue analysis in food and environmental samples.
