Abstract:
The impact of bed disinfectants for successful cocoon harvest and crop stability was successfully demonstrated in the farmer’s field during 2014-15. The study revealed that, application of Ankush vijetha green and slaked lime powder combination (T
3) bed disinfectant was recorded low incidence of silkworm diseases like grasserie (0.10 – 0.08 %), flacherie (0.25 – 0.15%) and muscardine (0.05 – 0.35%) and lower defective cocoon percentage
viz., stained cocoons (0.10 – 0.10 %), flimsy cocoon (0.30 – 0.04%) and uzi pierced cocoon (0.80 - 0.30 %) during
post rainy and
rabi seasons respectively. Further, single cocoon weight (1.821 g), shell weight (0.340 g), pupal weight (1.456 g), shell percentage (18.75 %), filament length (851.13 mtrs) and cocoon yield (81.10 kg/100 dfls) were recorded high in T
3 compared to application of bundh powder (T
1).
