Abstract

The success of silkworm cocoon crop in sericulture depends on a package of practices of technologies of which the role of disinfection assumes  great importance.  Many  disinfectants were developed, tested their efficacy  and being put to use in the laboratories and farmers fields.  Silkworm cocoon crop losses due to various bacterial, viral and fungal diseases vary from 10 – 50 % and in some cases rejection of the batches by the farmers.   To make the rearing shed disease free  was always a challenge to the farmers and infection in the later stages of rearing and consequent contamination of the forth coming batches were  the causes for continued crop losses.    Of late “Serifit” a new disinfectant  was developed by the  Central  Sericultural Research   and Training Institute, Mysore and the technology was put under Transfer to  the farmers  - the end users. Since it was a broad spectrum disinfectant, the same was demonstrated widely  in the six clusters under the command area of  Research Extension Centre, Gobichettipalayam

The new technology was  demonstrated to fifty farmers in cluster areas on free trial basis.  The guidelines of the technology were followed and the results were recorded.  Five farmers of the respective cluster areas  were kept as control, without using Serifit for disinfection. The yield improvement  was  recorded and the trial was repeated thrice.  The data showed a significant improvement of  an average  of 9 kg / 100 dfls.  Added to this, the crop losses due to the incidence of the most common silkworm disease -  grasserie   were reduced to almost nil and continuous use ensured successful disease  free silkworm crops.  Thus the technology was widely  popularized  and the material was being  procured in bulk quantity  and supplied on cost basis to the farmers  for the last two years. This has resulted in the increase in cocoon yield from  71 kg to 80 kg  / 100 dfls in the cluster areas.
