Abstract

The survey conducted in sericulture practising areas of Kashmir revealed that the incidence ofgrasserie diseases varied from 3.97 - 6.02% in South, Central and North Kashmir during 2016 and 2017. Significant differences were observed in the disease incidence between the three regions with the maximum incidence in south Kashmir (5.95Â±0.27) followed by central (5.30Â±0.23) and north Kashmir (4.80Â±0.12). It was found that the mean disease incidence of different rearing seasons was significantly low with Ankush (5.72Â±0.12) and the cocoon y ie ld /100 dfls and various economic parameters were significantly superior with Ankush in comparison to Rakshak, Resham Jyothi while Vijetha was taken as control. The p er cent reduction ofgrasserie disease over Vijetha as control was 4.98, 3.65 and 2.49 with Ankush, Rakshak and Resham Jyothi, respectively. The p er cent increase in yield over control was highest with Ankush (2.63) followed by Rakshak (1.50) and Resham Jyothi (0.23). Based on the results of the study, Ankush is recommended as silkworm bed disinfectant at farmers level in Kashmir.
