Cycloate-a thiocarbamate herbicide and a lipid biosynthesis inhibitor, finds its use in the control of annual grass weeds, perennial grasses, and annual broad-leaved weeds in spinach, sugar beet, fodder beet, and
beetroot.
Cycloate is not approved for its use in the European Union (EU) as a plant protection agent. This is in accordance with Regulation (EC) No 1107/2009 of the European Parliament and repealing the Council Directives 79/117/EEC and 91/414/EEC. But a default maximum residue limit (MRL) of 0.01 mg/kg has been set as per Art 18(1)(b) Reg 396/2005.

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
The cycloate CRM may also find given below uses:

• Solid phase extraction (SPE) followed by gas chromatography-mass spectrometry (GC-MS) analysis of 88 pesticide residues in strawberry, raspberry, blueberry, and grape samples
• Multi-residue determination of 118 pesticide residues in tea samples by solid phase extraction (SPE) and gas chromatography-mass spectrometry (GC-MS)
• Multi-class analysis of 21 pesticides in Chios mastic gum by QuEChERS for sample treatment, UHPLC for separation, and electrospray triple quadrupole mass spectrometry (ESI-MS/MS) for quantification
• Development and validation of a multi-residue method for the detection and quantification of 109 pesticides in tomato samples by modified QuEChERS based sample clean-up, followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS)
• Evaluation of a method for multi-class analysis of 170 pesticide residues in soya nutraceutical capsule samples by QuEChERS based extraction and GC-MS/MS quantitation
• Detection and measurement of 115 pesticide residues in 400 commercial orange samples by high-performance liquid chromatography-triple-quadrupole mass spectrometry (LC-MS/MS) coupled with modified QuEChERS based sample treatment
