Population dynamics of mustard aphid on different Brassica cultivars under terai agro-ecological conditions of West Bengal
type: item
description: Experiments were conducted at the Instructional Farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar during rabi season of 2002-03 and 2003-04 to study the population dynamics of mustard aphid on seven popular rapeseed-mustard cultivars. The incidence of aphid commenced from 52nd to 2nd standard week with a very low population levels on all the cultivars. The aphid (Lipaphis erysimi)population attained peak level from 7th to 9th standard week. The correlation coefficients between aphid population and different abiotic factors revealed contradictory results. Except for a few instances the weather parameters showed low order of associations with aphid population. Thus, the ecological factors exhibited little impact on the population build up of mustard aphid. The degree of infestation and the rates of population change of the aphids on different Brassica cultivars seem to be governed by varietal characteristics of different germplasms. Brassica campestris varieties as a group harbouredrelatively higher populations of the aphid than Brassica juncea varieties.

Developing site-specific appropriate precision agriculture
type: item
description: As conceived in the “West”, Precision Agriculture (PA) may be suitable for capital-intensive, high turnover economy, high technology monoculture and controlled management of a single major soil borne pathogen or pest across vast cultivated area but not for the peasant farming or the pest complex ridden unaided agriculture as in India. PA is not about an abstract of characterization. The specific values indicating variations in population at exact grids and helping the individual farmer in decision making in pest management at varied pesticide doses depending on varied soil pest population intensity and spatial distribution. Often it ends up in reducing the quantum of a pesticide threatened with withdrawal. We understand Appropriate PA (Appropriate Precision Agriculture, APA) as Site-Specific Appropriate Precision Agriculture (SSAPA) applied to cropping system management with withdrawal.

New pesticide molecules, formulation technology and uses: Present status and future challenges
type: item
description: Mankind has a history of using crop protection products from non-selective, naturally occurring compounds to highly specific synthetic and biological materials for assured food production and protection of environment since long time. There is a sequential rise in the production and consumption of pesticides in India during the last three decades. Researches are going on to develop safer molecules which could undergo photo-degradation, microbial degradation as well as chemical degradation leaving very less amount of residues in the environment. Conventional pesticide formulations like WP, EC etc are endangering human health and polluting environment. Newly developed modern formulations like water emulsifiable gel, floating granules, drift less dust, macro and micro encapsulated suspension, hollow fibers, monolithic matrix, laminated structures etc can avoid these problems. The prime motto for these developments is to give protection to the crops along with safety to the natural enemies of different pests as a whole safety to environment.

Rot diseases of muga host, Som (Persea bombycina) in Assam, India
type: item
description: Som (Persea bombycina, King. ex Hook. f. Kost.), the primary food plant of muga silkworm, (Antheraea assamensis Helfer) growing mainly in North Eastern region and Uttaranchal State in India. India is unique in producing the golden muga silk and has monopoly in global silk market grows up to 20-25 meters and survives for 18-20 years. Pollarding of Som plant at 6 ft height is a common practice in North Eastern region of India for controlled rearing (outdoor) of muga silkworm. It was observed that stems of som plant (specifically the pollarded plants) were generally infected with rot disease when it grows older. Phellinus contigus (under Polyporaceae), a white rot fungus, causes heart rot disease and Biscogniauxia mediterranea (= Hypoxylon mediterranea) (under Xylariaceae) causes canker rot disease of Som plant. A survey was conducted to study the infection of rotting pathogens on Som plants at Regional Muga Research Station (RMRS), Boko, Assam, India with during 2004-06. The disease incidence (DI %) caused by B. mediterranea was 12% while P.contigus showed 20% infection. Corelating the age of Som plants with susceptibility rot infection was found to be maximum in 10 years old plantation.
