General description

This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ. Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate. Download your certificate at: http://www.sigma-aldrich.com

Etridiazole is a fungicide primarily effective against oomycetes and widely used in controlling Pythium and Phytophthora species on agricultural and horticultural crops. Etridiazole causes the hydrolysis of cell membrane phospholipids into free fatty acids and lysophosphatides, leading to the lysis of membranes in fungi.


The drinking water standards have regulated a maximum contaminant level (MCL) for Etridiazole in treated waters. Australian drinking water guidelines set an MCL at 0.1 mg L-1. The European Union (EU) drinking water standards regulate a level for any pesticide at 0.0001 mg L-1 and the sum of all pesticides at 0.0005 mg L-1.

Etridiazole was included in Annex I to Directive 91/414/EEC on 1 June 2014 by Commission Directive 2011/29/EU and has been deemed to be approved under Regulation (EC) No 1107/2009, as per Commission Implementing Regulation (EU) No 540/2011, as amended by Commission Implementing Regulation (EU) No 541/2011. The inclusion in Annex I of Directive 91/414/EEC was restricted to uses of Etridiazole as a fungicide in non-soil bound systems in greenhouse. Maximum residue levels (MRLs) have been set according to Reg (EU) 2017/1777 for Etridiazole for various products of plant and animal origin from 0.05 to 0.4 mg/kg.

Application

The certified reference material can be used for the following:
  • To evaluate the teratogenic and developmental toxic effects of etridiazole on zebrafish embryos
  • Screening potential endophytic biofertilizers with fungicides tolerance and plant growth-promoting characteristics
  • To investigate the photodegradation of etridiazole by UV radiation at 254 nm during drinking water treatment
  • To determine the adsorption and desorption behavior of etridiazole and oxamyl on polyethylene sheets and polyvinyl chloride tubing used in horticulture
  • To develop a selective and sensitive analytical method for the determination of a carboxylic and a mercapturic acid metabolite of etridiazole in urine
