Herbicides for weed control during the entire growth period of dry direct-seeded rice were assessed in a field study.A miture of 47%halosulfuron-methyl · pretilachlor · isoproturon WP (1 650 g/hm2 ) was sprayed at a pre-emergence and then 20%quintrione SC (3 000 g/hm2 ) mixed with 15%ethoxysulfuron WP (90 g/hm2 ) and 10%cy-halofop-butyl EC (1 500 g/hm2 ) or 20% quintrione SC (3 000 g/hm2 ) mixed with 75%halosulfuron-methyl WDG (45g/hm2 ) and 10%cyhalofop-butyl EC (1 500 g/hm2 ) was applied at 4~5 leaf stages of rice.All the above treat-ments provided over 95%weed control efficacy and were safe to rice.
