We have found that 5-hydroxypyridazinones with N-1-azolyl substituents at the 4-position can have herbicidal activity on a broad spectrum of grass weeds at low use rates. In this presentation we will outline the chemistry used to prepare them, structure-activity profiles and summarize the biological activity of the class.
