EFFICACY AND ECONOMIC OF SULFOXFLOR 12% SL AGAINST SUCKING INSECT PESTS OF POTATO

Abstract

The field efficacy of sulfoxaflor 12% SL insecticide was evaluated against sucking insect pests (whiteflies
and leafhoppers) on seven popular potato cultivars (Kufri Chipsona-1, Kufri Anand, Kufri Chipsona-3, Kufri Surya, Kufri
Neelkhant, Kufri Bahar and Kufri Khyati) during 2018-19 and 2019-20. Results showed that, sulfoxaflor 12% SL exhibited
excellent activity against Bemisia tabaci (Gennadius) and Amrasca beguttula beguttula Isida during both the years. The
whitefly and leaf hopper population were low on protected potato cultivars as compared to unprotected cultivars. Similarly,
highest pooled mean tuber yield (49.33 t/ha) was recorded of K. Khyati when crop was protected by three sprays of
sulfoxaflor 12% SL followed by K. Anand (46.90 t/ha) and K. Bahar (40.56 t/ha). By working out cost benefit ratio it is
evident that K. Khyati ranked first indicating the maximum return of Rs. 3.18 per rupee invested followed by K. Chipsona-3
with Rs.2.54 and K. Anand Rs.2.47. The present study suggests the use of sulfoxaflor 12% SL is preferred insecticide and
could be incorporated in integrated pest management of sucking insect pests of potato.
