Sericulture Samruddhi
We are pleased to introduce a formulation of a Silk Enhancing Hormone “SAMRUDHI” by a joint technology developed by Central Sericulture Research and Training Institute, Mysore and Tokyo University of Agriculture and Technology, Japan.
“SAMRUDHI” is a juvenile hormone which increases the size and weight of the cocoons.
Our firm is the only licensed manufacturer of “SAMRUDHI” .The product is of low price in comparison to other products in the market.
Background
Administering chemical compounds to silkworm for rearing management and to get increase in silk yield has become popular among Seri culturists in India. The compounds may be either plant based or synthetic. Many are marveled by the visible impact of the application of the product on the uniformity of larval maturation and the resultant ease with which one could complete mounting the mature larvae.
Now a technology to increase the cocoon yield by administering a product on the 2nd or 3rd day of 5th instar has been developed. This product is an analogue of insect juvenile hormone (JHA) developed by SDS Biotech KK, Japan. CSRTI, Mysore has started a collaborative research programme with the Japanese concern to make it available to Indian farmers after elaborate field-testing. The main purpose of using this chemical is to make silkworm build heavier cocoons with higher silk content so that farmers get more cocoon yield (8-10 kg /100 dfls) and realers get 10% more silk yarn. However, to produce the higher yield, silkworms consume 2 feeds more with one day extra larval period. Subsequently, trials were conducted at the institute and at the farmer’s field. A total of about 21000 dfls were treated with JHA covering 141 farmers in 44 villages belonging to different areas of Karnataka and Tamil Nadu during the last eight months. Equal number of dfls were maintained as control for comparison. The results showed that the treated silkworms consume one or two extra feed and build bigger and heavier cocoons by 10-15% than the non treated larvae. The net return ranges from Rs.800 to 1200 based on the cocoon price in the market. Further, for every 100 dfls cocoon reeled, extra one kg silk has been obtained.
Methodology
The JHA product can be administered to any silkworm hybrid.
Time of application:
After 48h in 5th instar (3rd day) for bivoltine hybrid.
After 24h in 5th instar (2nd day) for multi x bivoltine hybrid.
Quantity of JHA to be used: One vial (5ml) for 50 dfls (20000 larvae) to be mixed in 2.5 liter of water.
Mode of application
Mix thoroughly one vial of JHA in 2.5 liters of water and spray the solution directly on the larvae (50 dfls) preferably in the morning when there is no leaves left on the rearing bed. Wait for 30-45 minutes and then give feeding. All regular procedures like Ankush/lime dusting can be followed as usual except on the day of treatment.
