Abstract:

Investigation was undertaken during 2015-2016 and 2016-2017on farmer’s field to study the bio-efficacy of newer insecticides against Plutella xylostella L. infesting cabbage. The cabbage crop (var. Saint) was raised by following recommended package of practices except for plant protection measures. Treatments included of six newer insecticides along with two conventional insecticides and one synthetic pyrethroid. Results revealed that all the insecticidal treatments were significantly superior over untreated control by recording lower larval population. Among the insecticidal treatments, significantly highest per cent larval reduction of P. xylostella over control was recorded in chlorantraniliprole treated plots (91.30 % with 1.02 larvae plant-1) followed by spinosad (87.55 % with 1.46 larvae plant-1) and flubendiamide (86.61 % with 1.57 larvae plant-1). The efficacy of insecticides also reflected on marketable yield of cabbage heads.The highest yield of 238.15 q ha-1with 129.23% increase over control was registered in the treatment of chlorantraniliprole followed by spinosad (233.83 q ha-1 with 125.07% increase over control) and flubendiamide (224.98 q ha-1with 116.56 % increase over control). The highest ICBR (1:16.40) was registered from chlorantraniliprole treated plots followed by flubendiamide (1:14.98) and spinosad (1:12.22).
