HERBICIDAL COMPOSITION AGAINST SCIYOS ANGULATUS L. COMPRISING DHNQ

摘要

PURPOSE: DHNQ(5,8-dihydroxy-1,4-naphthoquinone) is provided to suppress KAPAS(7-keto-8-aminopelargonic acid synthase) which is related to a biotin biosynthesis pathway of microbes and plants, and to significantly remove Sicyos angulatus L. with safety to human body. CONSTITUTION: An herbicidal composition for preventing Sicyos angulatus L. contains DHNQ of chemical formula 1 or a pharmaceutically acceptable salt thereof as an active ingredient. DHNQ is derived from black walnut and suppresses KAPAS activity. A method for controlling Sicyos angulatus L. comprises a step of treating Sicyos angulatus L., a seed thereof, or a habitat thereof with the herbicidal composition.
