Within the framework of an EU (European Union) project, field experiments were carried out in Italy, Spain, France, Greece, and Portugal during 1997 and 1998 to evaluate the efficacy of various pre- and postemergence herbicides for red rice control and their selectivity on water-seeded cultivated rice. Preemergence herbicides were applied under water-saturated soil conditions and rice was sown 15 to 20 days after treatment (DAT). Postemergence herbicides were applied at the 2-4 leaf stage of red rice on water-seeded rice sown 5 to 8 DAT. These trials indicated that the preemergence herbicides alachlor, acetochlor, dimethenamid, and metolachlor could be safely applied 15 days before rice sowing on emerged red rice seedlings grown under soil-saturated conditions. These herbicides generally controlled red rice with little effect on cultivated rice sown 15 d later. The poestemergence herbicides quizalofop, haloxyfop, fluazifop, cycloxydim, clethodim, sethoxydim, dalapon, glufosinate, paraquat, and glyphosate controlled red rice from 58% to 100%, and these herbicides can contribute substantially to red rice management.
