Chloridazon is a selective organochlorine herbicide that belongs to the group of pyridazinone compounds. It acts as systemic soil and leaf herbicide by inhibiting the photosynthesis process. It is used for pre-plant, pre-emergence, and early post-emergence, to control annual broad-leaved weeds, sugar beets, and red table beets.

Chloridazon is not authorized for use in the European Union as per the European Council Directive 91/414/EEC concerning the placement of plant protection products on the European market. Maximum residue levels (MRLs) have been set according to Reg (EU) 2016/1015 for Chloridazon for various products of plant and animal origin from 0.05 to 5 mg/kg.
Application
Chloridazon may be used as certified reference material for the following:
To examine the effects of chloridazon on the response of the frog neuroepithelial synapse to electrical stimulation and the basal values of the bioelectric parameters of the frog skin
To study the transformation of n-chloridazon in a fixed bed bioreactor for verification of microbial degradability at different dosed contamination levels and govern the adaptation processes
To investigate the effects of thermal and acid treatments on the sorption properties of a natural sepiolite by evaluating the adsorption process of chloridazon herbicide
To prepare and characterize controlled release formulations of chloridazon using biodegradable polymers like ethylcellulose and lignin
To investigate the potential use of lignin-based controlled release formulations (CRFs) to control release rate and leaching of metribuzin and chloridazon in soils
To synthesize a meso-sorbent silica/polyaniline (MSNPs/PANI) composite for the removal of the chloridazon pesticide from the aqueous solution
