A study was undertaken at Sukarpara Tea Estate, Bahadur, Jalpaiguri, in the state of West Bengal, to assess the effectiveness of Glyphosate 41% SL in controlling weed flora in Tea plantation during the kharif seasons of 2022 and 2023.There were six treatments that were replicated four.The experiment revealed that the application of Glyphosate 41% SL at 3.0 L ha-1 (1.23 kg a.i. ha-1)as formulation resulted in significantly lowest total weed density and dry weight and higher green leaf yield(34.8qha-1).Although, this treatment administered did not observe any significant impact on the overall population of fungus, bacteria, and actinomycetes. Thus application of Glyphosate 41% SL at 1.23 kg a.i. ha-1(3.0 L ha-1) was most effective in managing weed flora in tea plantation.
