Abstract
Potency of some modern insecticidal treatment schedules, viz T1 (Spiromesifen + Spiromesifen), T2 (Thiamethoxam + Thiamethoxam), T3 (Thiacloprid + Thiacloprid), T4 (Imidacloprid+ Imidacloprid ), T5 (Cartap hydrochloride + Cartap hydrochloride), T6 (Chlorpyriphos + Chlorpyriphos) and T7 (control) were evaluated against Agrotis ipsilon (Hufner) and mole cricket, Gryllotalpa africana, P.de. Beau. in single potato variety, Kufri Jyoti during rabi season of two potato-growing years in 2015-2016 and 2016-2017 from November to February. Among the seven different treatment schedules foliar spray of thiamethoxam 25 WG @125 g a.i/ha after emergence+ second spray with thiamethoxam 25 WG @ 125 g a.i./ha after 15 days of first spray (T2), followed by T1 i.e. treatment with foliar spray of Spiromesifen 240 S.C. after emergence @ 96 g a.i./ha + second spray of Spiromesifen 240SC @ 96 g a.i./ha after 30 days of first spray, respectively, was found most effective in reducing the soil pest infestation and potato tuber damage caused by different soil pests. Cost benefit analysis revealed that T2 was most effective and T1 was at par with T2.
