Mulberry shoot
briquettes as fuel
Commercialized
Waste stems & shoots are available through out the
year in sericultural clusters as silkworm rearing is a
continuous activity. Huge quantity of shoots left
after rearing is over is woody with high C: N ratio
and are not suitable for compost preparation unless
crushed. Farmers use these shoots as fuel for
various domestic purposes. To enhance the utility of
these mulberry waste shoots and also to protect the
environment, the present technology has been
developed where in briquettes are produced out of
left over biomass, which is at par with high quality
coal.

Tasar host plant based integrated farming system
comprising of leguminous and other cash crops
been found economically viable and remunerative
for the tasar growers. Net income from the system
ranges from Rs. 23,000 to 41,000/ha with additional
income of Rs. 4000 – 18000/- per hectare from
intercropping of the leguminous crops
Integrated farming system with vegetable and
horticultural crops increased the farmers income
Combination of fodder crop, horticulture, forestry,
animal husbandry etc., Mulberry based integrated
farming system has effectively brought about
enterprise diversification for sustainability and also
augment income generation through better
management of farm resources. The highest net
farm income at farmer’s field comes from Field
crop+ mulberry +Vegetable cropping system. It is
being adopted by farmers having sufficient
resources.
Integrated disease management technologies have
been developed for control of foliar and soil borne
diseases of mulberry involving microbial agents like
Trichoderma species, Pseudomonas species etc.,
Similarly a new bio-formulation for control of root
rot disease in mulberry ‘Navinya’ a 80% plant based
products developed for effective control of the
disease in mulberry gardens.
Pupa oil is rich in PUFA (Poly unsaturated fatty
acid). It contains oleic, palmitic, stearic, palmitoleic,
linolenic, linoleic, arachidic, myristic, lauric acids
and phospholipids and used as massage oil, paints,
varnish soaps, candle industry, pharmaceuticals,
bio-diesel, and plasticiser.
Sericin refined from cocoon/silk contains 18 amino
acids besides 8 essential amino acids, which are
necessary for human body. It is an excellent protein,
antioxidant, coagulant, and chemo protective and
nutrient supplement. Sericin can be used as raw
material for manufacturing moisturizing creams and
lotions in cosmetics because of its high moisture
absorption and preservative ability. The Institute
also developed a sericine rich (95%) silkworm hybrid
for this purpose.

Silk fibroin has many functional applications in
biomedical industry viz. cosmetics, toiletries,
pharmaceutical preparations, tissue regeneration
and repair, scaffolds and matrices. It has an
excellent natural moisture-adjusting property. It is
used as cosmetic for dry skin. It prevents and cures
dermatitis and keeps the skin hygiene. It is a highly
promising protein and a potential biomaterial.
A classical biological control for management of
papaya mealy bug a invasive pest using effective
parasitoid viz., Acerophagus papayae was
developed 2010 which prevented farmers of Tamil
Nadu by uprooting the mulberry.
Eighteen staff of different units was trained in mass
production and five mass production units were
established to mass-produce the parasitoid which
helped in control of papaya mealy bug in a very
short span.
The existing CRC technology has been fine tuned to
suit the requirement of bed space and quantum of
leaf for the increased number of grains from 50,000
to 60,000 per 100 DFLs. It is popularized and used
by CRCs.
The antiviral protein (BmNox) has been cloned,
sequenced and expressed. The protein marker is
being used as a marker for developing NPV tolerant
silkworm breeds.
Developed a package involving seri residue compost
enriched with useful and antagonistic microbes
along with neem oil cake for control of root
diseases in mulberry and curtailing FYM up to 10
MT/ha besides improving the soil health.
