The present toolkit on ‘Coastal Biovillages’ has been prepared based on practical experiences gained by M.S.Swaminthan Research Foundation from Biovillage projects conducted since 1991 in the villages of Pondicherry and later in the coastal villages of Pichavaram and Gulf of Mannar regions of Tamil Nadu.
In this tool kit, section one to seven gives useful guidelines covering various essential aspects for the Biovillage practitioners, followed by the annexure, which gives details of selected...
BIOVILLAGES: Paradigm of Human-Centered Sustainable Development
In response to the invitation by the Government of Pondicherry (now known as Puducherry) the Biovillage project was initiated in March 1991 in Pondicherry. In China, a similar programme “Qianxian Biovillage Model”
was initiated in five regions of the Hubei province of Huairou Country of Beijing, by the Chinese Academy of Sciences (CAS). CAS is a leading academic institution and comprehensive research and development centre in natural science, technological science and high-tech innovation in...
The Biovillage Programme completed 20 years of its eventful journey. In the course of these two decades, the Programme has touched and transformed many lives for the better, especially the poor and the
marginalised, in 50 villages of Puducherry.
Knowledge Enhancement and Pest Management among Farmers through Picture based advisories- Case study from Tamil Nadu
Farmers particularly smallholder farmers in India are increasingly getting exposed to adverse impacts of
climate change and extreme weather events. The increased vulnerability to different abiotic (weather) and
biotic risks (pests, diseases, nutrient disorders, weeds etc.) and accompanying productivity and agricultural
income losses discourage farming households from investing in both productivity enhancing innovations as
well as human capital development. The new technological advancements in...
Dodonaea angustifolia - a potential biopesticide against Helicoverpa armigera
Dodonaea, a common hop bush and a perennial shrub belonging to Sapindaceae is known for its folk remedies. It is distributed from the coast to 2000 m elevated terrain. It is the most aggressive colonizer on disturbed ground, even in rocky gravel or limestone. D. angustifolia L.F., predominantly present in India, has a wide range of therapeutic applications since ancient times against pneumonia and othe pulmonary diseases including tuberculosis. A decoction of the plant or the wood is used as a...
Ovicidal activity of crude extracts of few traditional plants against Helicoverpa armigera (Hubner) (Noctuidae: Lepidoptera)
Cipadessa baccifera Miq., Melia dubia (Cav.) (Meliaceae); Clausena dentata (Rutaceae) and Dodonaea angustifolia (Sapindaceae) are common medicinal plants found in Western Ghats and are used traditionally for various purposes. The petroleum ether, chloroform, hexane, acetone and water extracts of the leaves were investigated for their ovicidal property against Helicoverpa armigera (Hubner) (Lepidoptera : Noctuidae). The different extracts of the test plants differed significantly in their...
Efficacy of Roccella monatgenei Extracts on Helicoverpa armigera (Lepidoptera: Noctuidae)
The insecticidal activities of hexane, ethyl acetate, methanol and water extracts of lichen, Roccella montagnei Bel. emend. Awas, were assayed against polyphagous insect, Helicoverpa armigera (Hubner). Among the different crude extracts tested, the popation was nil in methanol (1%)and hexane extract (5%), which was on par with aqueous extract (5%). The formulation of water extract of R. montagnei is better compared to other solvent extracts, as potential antipest agent against H. armigera
Efficacy of Dodonaea angustifolia Crude Extracts against Spotted Bollworm, Earias vitella (Fab.) (Lepidoptera: Noctuidae)
A field experiment was conducted in Sorapet, Pondicherry, Union Territory, India, to evaluate the efficacy of crude extracts of D. angustifolia against Earias vitella on rainfed cotton D. angustifolia crude extracts drastically reduced the number of larvae similar to aneem product. The percentage of damaged squares and bolls was also reduced after consecutive sprays compared to untreated and endosulfan (controls).
Efficacy of Cipadessa baccifera leaf extracts against gram pod borer, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)
Cipadessa baccifera, a common medicinal plant of Western Ghats was evakyated fir insecticidal property
against Helicoverpa armigera. The different extracts of leaves differed significantly in their efficacy with the hexane extract being the most effective in curtailing the fecundity and egg hatchability in the first generation adults. The insecticidal effect against the resultant progeny proved that petroleum ether extract could cause significant reduction in pupation and pupal weight and...
Efficacy of Beauveria bassiana (Balsamo) Against Red Flour Bettle, Tribolium castaneum (HERBST)
White muscardine fungus, Beauveria bassiana, was evaluated for its insecicidal activity against grubs, pupae and adults of the red flour beetle, Tribolium castaneum. In general, prolongation in grub and pupal duration was observed. As a Subsequent effect, malformed adults were evident. The adult mortality (%) increased with the increase in exposure period and conidia concentration. This proved that the time of dipping and spore concentration greatly influenced the insecticidal effects of the...
