Sweet sorghum, crucial for sugar and energy production, could help Egypt meet rising sugar demands but suffers from low productivity due to inadequate agronomic practices. Improving these practices could enhance its contribution alongside sugarcane and sugar beet. The aim of the research is to study Bio efficacy of different herbicides for economical weed management in sweet sorghum [Sorghum bicolor (L.) Moench] and their residual effect on succeeding crops. This experiment was carried out in Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh (Gujarat). The experiment comprising 10 treatments was laid out randomized block design with three replications The sweet sorghum (SSV 84) was sown with standard package of practices. On the basis of the results obtained from the present two-years field study, it can be concluded that effective control of complex weed flora with profitable production in rabi sweet sorghum can be obtained by PE application of atrazine 50 WP 500 g/ha fb mesotrione + atrazine 44.97 SC (Premix) 875 g/ha at 30 DAS. Saurashtra Agro-climatic Zone of Gujarat. There is no residual phytotoxicity of above mentioned pre and post-emergence herbicides through field bioassay

On the basis of the results obtained from the present two-years field study, it can be concluded that effective control of complex weed flora with profitable production in rabi sweet sorghum can be obtained by PE application of atrazine 50 WP 500 g/ha fb mesotrione + atrazine 44.97 SC (Premix) 875 g/ha at 30 DAS. Alternatively, PE application of atrazine 50 WP 500 g/ha + IC & HW at 30 DAS can be employed according to availability of labourers under medium black calcareous soil of South Saurashtra Agro-climatic Zone of Gujarat. There is no residual phytotoxicity of above mentioned pre and post-emergence herbicides through field bioassay and it is safe to grow succeeding groundnut, sesame, pearl millet and soyabean after rabi sweet sorghum crop
