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
