Abstract: The current investigation was carried out to study the efficacy of different pre and post emergence of herbicides and their combinations along with weeding and hoeing operation to control the weed in wheat at post graduate research farm, R.C.S.M. College of Agriculture, Kolhapur (MS) in randomized block design with eights treatments and three replication during Rabi season of 2016-17 on medium black soil. The weed intensity of weed free check at 42, 56 DAS and at harvest was significantly minimum as compare to rest of all treatments. Weed count and dry matter of weeds at harvest were significantly lowest in weed free check (2.13 m-2) and (0.20 q ha-1), respectively. Among the integrated weed management weeding at 20 DAS and + metasulfuron methyl @ 4 g a.i. ha-1 as PoE at 30 DAS (T5) recorded (7.17 m-2) weed count and (0.54 q ha-1) dry matter of weed and hoeing at 20 DAS + metasulfuron methyl @ 4 g a.i. ha-1 as PoE at 30 DAS (T4) recorded (17.66 m-2) weed count and (1.36 q ha-1) dry matter of weed were comparable with weed free check. The significantly highest weed control efficiency was recorded by weed free check (93.45%) followed by weeding at 20 DAS and + metasulfuron methyl @ 4 g a.i. ha-1 as PoE at 30 DAS (82.23%) and T4 i.e. hoeing at 20 DAS + metasulfuronmethyl @ 4 g a.i. ha-1 as PoE at 30 DAS (55.88%). The integrated weed management practices weeding at 20 DAS and + metasulfuron methyl @ 4 g a.i.ha-1 as PoE at 30 DAS (T5) recorded lowest weed index (3.42%) followed by T4 i.e. hoeing at 20 DAS + metasulfuron methyl @ 4 g a.i. ha-1 as PoE at 30 DAS(6.69%). Weed free check showed lowest species wise weed count over rest of treatments. The more number of monocot and dicot weeds were observed in weedy check over rest of treatments. The comparable results were observed by weeding at 20 DAS and + metasulfuronmethyl @ 4 g a.i. ha-1 as PoE at 30 DAS (T5) and hoeing at 20 DAS + metasulfuron methyl @ 4 g a.i. ha-1 as PoE at 30 DAS (T4), respectively.
