In-vitro efficacy of medicinal botanical and different groups of bacteria associated with flacherie disease of silkworm (Bombyx mori L.).

摘要

The in-vitro effect of different medicinal botanicals on flacherie disease causing bacteria showed significant effect on inhibition zone. The statistical data revealed that the inhibition zone of Bacillus sp. (hemolymph) was found to be significant on first and second day of observation. However, among the botanicals the minimum inhibition zone of 6.45 mm and maximum of 11.08 mm were recorded for (T₅) Solanum nigrum and (T₂) Aegle marmelos, respectively. Further, concentration of the botanical extracts also recorded significant results. With respect to zone of inhibition, minimum and maximum of 5.86 and 6.23 mm; 6.82 and 7.28 mm were recorded for first and second day at 1:3 and 1:1 concentration, respectively compared to control. The same trend was noticed on inhibition zone of Bacillus sp. (midgut) on different medicinal plant extracts as reflected in experimental data.
