Order of the National Green Tribunal in the matter of In Re: News Item titled "Nayar river is vanishing - a yatra reveals conservation goes beyond science and policy" appearing in ‘The Down To Earth’ dated 03.06.2025. The original application was registered suo-motu based on the news item titled "Nayar …
Given that the controversy over success and failure of Bt technology still exists, this paper discusses the available field studies that have addressed agro-economic questions of Bt cotton cultivation in India. Since a meta-analysis of studies can give only partial conclusions, owing to differences across study methodologies and coverage, this …
‘Spread of the Bt gene could make brinjal a problematic weed' An independent enquiry has revealed that the cultivation of genetically engineered (GE, also called genetically modified, or GM) Bt brinjal poses risks to the environment and possibly to human health. The occurrence of wild, weedy and also cultivated relatives …
In the present study an indigenous biopesticide formulation (BPF) comprising easily accessible botanicals along with cow urine, was evaluated for its efficacy against insect pests of tomato crop under field. BPF gave promising results in controlling tomato fruit borers and afforded substantial yield of the produce. The BPF treatment could …
This note has reference to the correspondence: ‘Bt cotton: refuge in mixed bag’ by Muralimohan and Srinivasa. In fact, their article itself was in response to an earlier correspondence entitled ‘Bt resistance in Helicoverpa species: Indian policy needs urgent revision’ by Hanur, in which the author has advocated ‘refuge in …
The energy audit of North Indian tea factories will begin shortly, according to Mr M.G.V.K. Bhanu, Chairman of the Tea Board of India. Talking to Business Line here on Wednesday, Mr Bhanu informed that the Tea Board has already completed the exercise for nearly 200 tea factories in South India. …
Questions have been raised about the transparency and scientific quality of regulatory processes applied in the first open field releases of genetically modified (GM) insects, and there is concern that inappropriate precedents have been set, particularly through generic risk assessments covering multiple species and technologies. The GM insects tested in …
After many years of open discussion and development, the first genetically modified (GM) insect strains are entering field trials. A key engineered trait renders the insects “genetically sterile”, such that some or all of their offspring die; the insects additionally carry a fluorescent marker gene for easy identification. Such “genetic …
Experimental releases of genetically modified (GM) insects are reportedly being evaluated in various countries, including Brazil, the Cayman Islands (United Kingdom), France, Guatemala, India, Malaysia, Mexico, Panama, Philippines, Singapore, Thailand, the United States of America, and Vietnam. GM mosquitoes (Aedes aegypti) have already been released for field trials into inhabited …
Field trials were conducted for the validation of integrated pest management (IPM) package for the castor and pigeonpea intercropping system in rainfed agro-ecosystem for the state of Andhra Pradesh, India during 2002 and 2003 seasons.
Pest control is one of the areas in which population dynamic theory has been successfully applied to solve practical problems. However, the links between population dynamic theory and model construction have been less emphasized in the management and control of weed populations. Most management models of weed population dynamics have …
The brown planthopper Nilaparvata lugens (Stål) is the most serious pest of rice across the world, especially in tropical climates. N. lugens nymphs and adults were exposed to high temperatures to determine their critical thermal maximum (CTmax), heat coma temperature (HCT) and upper lethal temperature (ULT). Thermal tolerance values differed …
This article studies the development of the Non-Pesticidal Management Project (NPM) that emerged in the late 1980s in Andhra Pradesh's Warangal district of the semi-arid region Telengana as a response to accumulating agrarian distress, when chemical pesticides did not help to counter massive pest infestations.
With an aim to bring about the second green revolution through adoption of effective scientific agricultural methods, the Indian Council of Agricultural Research (ICAR) under Agriculture Ministry has proposed 100 more Krishi Vigyan Kendras (KVK) across the country in the 12th Plan. In a proposal sent to the apex planning …
Parasitoid disturbance populations in agroecosystems can be maintained through the provision of habitat refuges with host resources. However, specialized herbivores that feed on different host plants have been shown to form host-specialized races. Parasitoids may subsequently specialize on these herbivore host races and therefore prefer parasitizing insects from the refuge, …
Studies to understand the Bacillus thuringiensis (Bt) resistance mechanism in European corn borer (ECB, Ostrinia nubilalis) suggest that resistance may be due to changes in the midgut-specific Bt toxin receptor. In this study, we identified 10 aminopeptidase-like genes, which have previously been identified as putative Bt toxin receptors in other …
GM crops are being cultivated for the last 15 years in many countries and culminating in the last year, GM crops were planted in more than 1 billion hectares (b ha) by nearly 15 million farmers. In India, about 6.3 million farmers cultivated Bt cotton last year (http://www.isaaa.org) in more …
The Animal Welfare Board of India (AWBI), a statutory body of the central government, has issued an advisory to chief secretaries of all state governments and the Indian Pest Control Association to prohibit the use, sale and manufacture of glue traps to catch rodents, as they are harmful to the …
Indian agriculture has been under stress quite for long time. Decline in public investment, poor extension net work, lack of marketing facilities, erratic input supply and others have all collectively contributed for decline or stagnant in Indian agriculture. Increasing use of synthetic inputs and non-judicial use of natural resources including …
Cotton leaf curl virus disease is one of the major threats for cotton production and has emerged as a serious disease of cotton in North India. Cotton leaf curl disease (CLCuD) is caused by a geminivirus, transmitted by whitefly (Bemisia tabaci) vector. Genetic engineering of cotton transgenics resistant to CLCuD …
