Environmental ProfileEnvironmental fate:
Animals:In mammals, following oral administration of flamprop-M-methyl or flamprop-M-isopropyl, complete metabolism and excretion occurs within 4 days.Soil:The major soil degradate from both esters is flamprop free acid.Plant:In plants, flamprop-M-methyl and flamprop-M-isopropyl are hydrolysed to the biologically-active flamprop acid, which then undergoes conversion to a biologically-inactive conjugate. -
Transport InformationHazard Class:III(Slightly hazardous)
