What is Pyraclostrobin?

Plain description, key identifiers and synonyms

Pyraclostrobin is a carbamate ester that is the methyl ester of [2-({[1-(4-chlorophenyl)-1H-pyrazol-3-yl]oxy}methyl)phenyl]methoxycarbamic acid. A fungicide used to control major plant pathogens including Septoria tritici, Puccinia spp. and Pyrenophora teres. It has a role as a xenobiotic, a mitochondrial cytochrome-bc1 complex inhibitor, an environmental contaminant and an antifungal agrochemical. It is a carbamate ester, a member of pyrazoles, an aromatic ether, a member of monochlorobenzenes, a methoxycarbanilate strobilurin antifungal agent and a carbanilate fungicide.
