History Launched by BASF in UK in 1998. Reported by W. Nuyken et al., Proc. Br. Crop Prot. Conf. - Weeds, 1999, 1, 81; see also references therein. Manufacturers BASF

Biochemistry Protoporphyrinogen IX oxidase inhibitor. The accumulated protoporphyrinogen then acts as photosensitiser, promoting the formation of the radical oxygen species in the cells. This toxic agent causes lipid peroxidation which results in membrane disruption. These effects quickly lead to cell death and tissue disiccation. Mode of action Acts primarily by contact action, with no acropetal or basipetal translocation. Uses For post-emergence control of annual broad-leaved weeds, especially Galium aparine, Lamium spp., and Veronica spp., in winter and spring small grain cereals, at 50 g/ha. Phytotoxicity The most sensitive crop to pre-emergence application is sugar beet. Formulation types EC. Compatibility Known to be incompatible with diclofop-methyl, fenoxaprop-P-ethyl and difenzoquat metilsulfate. BASF recommend that cinidon-ethyl should be mixed only with isoproturon, chlormequat chloride and 'Duplosan' formulations. Selected products: 'Lotus' (BASF)

'Bingo' (BASF); 'Orbit' (BASF); 'Solar' (BASF); 'Vega' (BASF) mixtures: 'Lotus D' (+ 2,4-D-isoctyl) (BASF)

Readily biodegradable in soil and water. Animals Following limited, but rapid, absorption, and widespread distribution in organs and tissues, the a.i. is extensively metabolised and rapidly excreted. Plants The a.i. is extensively metabolised; no bioavailable components of the residues present in grain are likely to be found at toxicologically significant levels. Soil/Environment Soil DT50 0.6-2 d (lab., aerobic conditions, 20 °C); rapidly mineralised. Rapidly degraded in water; decomposition increases with increasing alkalinity. Not stable photolytically in water.
