Abstract
Nel triennio 1995-97 sono state effettuate prove sperimentali per verificare l'efficacia di diversi erbicidi nei riguardi del riso crodo, impiegati con la tecnica della falsa semina. La sperimentazione ha previsto i seguenti confronti: 1995: quizalofop-etile-isomero D (75 g/ha p.a.), ciclossidim (600 g/ha p.a.), dalapon (12.750 g/ha p.a.), glifosate trimesio (640 g/ha p.a.), glifosate (720 g/ha p.a.), alossifop-etossietile (150 g/ha p.a.) e cletodim (140 g/ha p.a.); 1996: quizalofop-etile isomero D (150 g/ha p.a.), ciclossidim (900 g/ha p.a.), dalapon (12.750 g/ha p.a.), dimetenamide + dalapon (630 g/ha p.a. + 10.200 g/ha p.a.), cletodim + olio minerale (189 g/ha p.a. + 1.000g/ha), cletodim + olio minerale (283 g/ha p.a. + 1.000 g/ha), oxadiazon + glifosate (300 g/ha p.a. + 1.260 g/ha p.a.) e glifosate trimesio (960 g/ha p.a.); 1997: cletodim (283 g/ha p.a.), ciclossidim (900 g/ha p.a.) e dalapon (12.750 g/ha p.a.).
