Abstract
Background and Objective: Indiscriminate use of herbicide poses serious concern as it encourages herbicide resistance development in weeds and makes weed control a difficult task.The present study was undertaken with a view to select suitable post-emergence herbicides for puddle-transplanted rice. Materials and Methods:The experiment included ten post-emergence herbicides along with a weed-free control and a weedy check in a randomized complete block design with three replications.Results: The proprietary mixture of bispyribac sodium+bensulfuron methyl showed the best weed control efficacy (83%) followed by penoxulum (80%), proprietary mixture of bensulfuron methyl+quinchlorac (74%), ethoxysulfuran (63%) and pyrazosulfuran ethyl (54%).Satisfactory grain yields were obtained from proprietary mixture bispyribac sodium+bensulfuron methyl (5.28 t haG 1 ), ethoxysulfuron (5.06 t haG 1 ), proprietary mixture of bensulfuron methyl+quinchlorac (5.01 t haG 1 ), penxosulum (5.0 t haG 1 ) and 2,4-D amine (4.85 t haG 1 ) while, pyrazosulfuron ethyl (3.55 t haG 1 ) and MCPA500 (3.92 t haG 1 ) showed the worst performance similar to that of the weedy plot (3.40 t haG 1 ).Conclusion: The alternate use of any of the post-emergence herbicides like a proprietary mixture of bispyribac sodium+bensulfuron methyl, bensulfuron methyl+quinchlorac and single herbicide of ethoxysulfuron, pyrazosulfuran ethyl and penoxulum could be used effectively to control weeds in puddle transplanted rice.
