Sofit, a new herbicide for use in direct-seeded rice (wet-sown rice)

Sofit is a new herbicide discovered for use in mud-sown rice (tropical/subtropical conditions) as well as in water-sown rice in the temperate climate zones. Sofit consists of a mixture of pretilachlor, 2-chloro-2, 6-diethyl-N-(2-propoxyethyl)-acetanalide, a new highly active early season herbicide for use in transplanted rice, and a safening agent CGA 123'407, 4,6-dichloro-2-phenyl-pyrimidine. This new safening agent, CGA 123'407 permits the safe application of pretilachor as a pre-emergence herbicide in direct-seeded rice. The broad activity spectrum of Sofit includes control of the most important rice weeds such as Echinochloa spp., sedges and various broadleaf weeds such as Monochoria vaginalis (Burm f.) Presl.
