Online published on 31 July, 2023. Abstract To study the effectiveness of some bio-rational management tools against sugarcane woolly aphid, experiments were conducted during 2017-18 and 2018-19 at UBKV, Pundibari, Cooch Behar (WB), India. Based on pooled analysis, the cumulative efficacy of the treatments 14 days after application was in the range of 36-100%. The treatments of imidacloprid (100%) and Verticillium lecanii (68.7%) were significantly superior to other treatments. While Metarhizium anisopliae (58.4%), azadirachtin (56.8%) and Beauveria bassiana (49.9%) were moderately effective and neem oil (35.8%) was found less effective against C. lanigera.
