Pyraclonil is a proporphyrinogen oxidase (PPO) inhibitor. Pyraclonil is a herbicide agent and is highly effective in controlling the susceptible (S) and multiple-herbicide-resistant (MHR) E. indica populations[1]. Pyraclonil is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
Pyraclonil has a good control effect on both susceptible (S) and resistant (R) populations, showing fresh-weight reductions of 94.5-94.9 and 89.5-90.4%, respectively[1].
