Effect of acaricides on yellow mite, Polyphagotarsonemus latus infestation in jute and its response to fibre yield

Sohanur Rahman, Sahin Polan, Nazrul Islam and Arifur Rahman

The experiment was carried out at Entomology department, Bangladesh Jute Research Institute (BJRI), Dhaka, Bangladesh for dose fixation and in the field of two different locations viz. Jute Agriculture Experimental Station (JAES), Manikganj and Jute Research Sub-Station, Tarabo, Narayanganj were selected for evaluation of nine acaricides against jute yellow mite during the jute growing season (April-August) 2018 & 2019 following Randomized Complete Block Design (RCBD) with three replications. Revenge 1.8EC(Abamectin 1.8%), Power Prid 95SP (Cartap 92% + Acetamiprid 3%), Lock 12SC(Chlorphenpyr 10%+ Emamectin Benzoate 2%), Parker 75 WG (Acetamiprid 50% + Buprofezin 25%), Brinka 24 SC (Spirodiclofen 24%), Guardian 40WDG(Emamectin Benzoate 20% + Thiamethoxam 20%), Aceto 40WDG(Acetamiprid 40%), Flame38WDG(Abamectin 2%+ Imidacloprid 36%), Aim Zox 10EC(Hexythiazox 10%EC) @ 600ml/ha, 600ml/ha, 600ml/ha, 600ml/ha, 500ml/ha, 600ml/ha, 600ml/ha, 600ml/ha, 225gm/ha, 600ml/ha, 600ml/ha, 500ml/ha, 280ml/ha and 30gm/ha respectively respectively were found effective and economic in the pot experiment for controlling jute yellow mite at 3th day after spray. Among these insecticides, the highest percent reduction of jute yellow mite in 2018 (97.12%) as well as more yield (3.17 ton/ha) over control was found in plot treated with Revenge 1.8EC (Abamectin 1.8%) in Manikganj. In 2019, the highest percent reduction of jute yellow mite (96.45%) was found in plot treated with Lock 12SC (Chlorphenpyr 10%+ Emamectin Benzoate 2%) and highest in Manikganj and highest yield (3.20ton/ha) was found in Aim Zox 10EC (Hexythiazox 10%EC) treated plot in narayanganj. Overall, All tested insecticides were found effective significantly giving more than 88% reduction of infestation and more than 2.45 ton/ha fibre yields at both field experiments at two years.
