Carfentrazone-ethyl is a broadleaves post emergence herbicide discovered by FMC. It belongs to triazolinone family and is a PPO [protoporphyrine oxidase] inhibitor with contact action. Carfentrazone is selective in cereals, maize(US), rice, fodder grasses. Key sensitive weeds in cereals are Galium aparine, Veronica hederifolia, Lamium sp, but it also provides outstanding efficacy on a wider range of weeds such as Solanum nigrum, Chenopodium album and Amaranthus retroflexus. Carfentrazone-ethyl is active at low dose rates (c.20 g/ha). It gives optimum results against young weeds, which are controlled within 1 to 2 weeks. These characteristics make carfentrazone-ethyl an ideal partner for other commonly used cereal herbicides such as sulfonylureas, diflufencan and phenoxies. In addition, carfentrazone-ethyl also has a very good toxicological and environmental profile, including a very short half-life in soil and water. Such properties are the driving force behind carfentrazone-ethyl becoming a major broadleaf herbicide in cereals.
