Abstract: Premise of the study. In India and elsewhere, transgenic Bt eggplant ( Solanum melongena ) has been developed to reduce insect herbivore damage, but published studies of the potential for pollen-mediated, crop- to- wild gene fl ow are scant. This information is useful for risk assessments as well as in situ conservation strategies for …

Abstract: Transgenic Bt-cotton is commercially cultivated on the rationale that it produces toxins that defend the plants primarily from caterpillars damaging cotton bolls. From the context of crop protection, it is important that these bollworms remain susceptible to the toxins, so that their populations are under check. However, if certain individuals are able to survive …
Abstract: Several studies have found that biotechnology crops increase yield and reduce the use of pesticides. These studies failed to consider the long–run growth of the pest population as it becomes more resistant to both pesticide–producing crops and the pesticides. There is evidence that biotechnology crops do not prevent pest density from growing and different …
Abstract: Although planting of genetically modified (GM) crops has topped 148 million ha. worldwide, direct consumption of GM foods remains extremely rare. The obstacles to GM foods are highly varied and they can provide windows into important cultural dynamics. India’s heated controversy over its would-be first GM food—Bt brinjal (eggplant)—is driven not only by common …
Abstract: BACKGROUND The inheritance and phenotypic expression of resistance to Bacillus thuringiensis Cry1Ac insecticidal protein were studied in selected populations of pink bollworm, Pectinophora gossypiella (Saunders), that were collected from Bollgard cotton in India. The individual populations in the pool were Cry1Ac resistant and sourced from Cry1Ac‐containing Bt cotton (Bollgard) hybrids in 2010. RESULTS Laboratory …
Abstract: BACKGROUND. The pink bollworm is one of the most destructive pests of cotton. Transgenic cotton producing Bt toxin Cry1Ac or a combination of Cry1Ac and Cry2Ab2 has been used effectively against this pest. However, some other insects have evolved resistance to Bt toxins in the field. During the 2007-2008 and 2008-2009 seasons, pink bollworm …
Abstract: Introduction of genetically modified crops (GM Crops) has been entranced in severe controversies in India. Following Bt-Cotton, Bt-Brinjal the first genetically modified food crop, has caused a conflict of beliefs and generated heated debates regarding its safety throughout the length and breadth of the country. The Government of India is caught between strong proponents …
Text: We have just completed screening of horseweed (marestail) seed samples collected in the fall of 2004 for tolerance to glyphosate. The purpose of this article is to briefly summarize the methods used in this process and show the newest counties which have documented populations of glyphosate-resistant horseweed. This project is a three-year process in …
Abstract: Agriculture Times of yore in AgBioForum, current science and many agriculture journal issues have been discussed Bt cotton safety (Manjunath 2011) controversies (Geeta Bharathan 2001), success (Camille Gonsalves 2007), resistance issues (Akshaya et al., 2010) and cost-benefit analysis (Manjunath 2011) in India a question rose as to “Bt or Non-Bt”. Therefore, a typical collective …
Abstract: A fresh controversy has erupted over Bacillus thuringiensis (Bt) cotton after the publication of a study by a government institute in India showing that Bt cotton planted in India is not as efficient in killing bollworms there as it is in the US or China. Keywords: Bacillus thuringiensis (Bt), Bt cotton, India, bollworms, efficacy …
Abstract: Genetically modified foods (GM foods) are foods derived from genetically modified organisms (GMOs). GMOs have had specific changes introduced into their DNA by genetic engineering techniques. Countries like India that have food security concerns and have small and marginal farmers practicing an integrated type of agriculture have specific problems for which they seek solutions. …
Abstract: Although India’s cotton sector has been penetrated by various input- and capital-intensive methods, penetration by herbicide has been largely stymied. In Telangana State, the main obstacle has been the practice of ‘double-lining’, in which cotton plants are spaced widely to allow weeding by ox-plow. Path dependency theory primarily explains the persistence of sub-optimal practices, …
Abstract: Fish proteins occupy an important place in human nutrition. They are well balanced with essential amino acids and are comparable to other proteins of animal origin. Moreover, carbohydrate content of the fish flesh is very low. Considering their nutritional value, it is essential for any nation, which is desirous of developing this rich protein …
Abstract: Background. Cotton with coevolving pests has been grown in India more than 5000 years. Hybrid cotton was introduced in the 1970s with increases in fertilizer and in insecticide use against pink bollworm that caused outbreaks of bollworm. Hybrid Bt cotton, introduced in 2002 to control bollworm and other lepidopteran pests, is grown on more …
Abstract: Scholars in many disciplines have approached the question of how humans combine environmental learning (or empirical assessments) and social learning (or emulation) in choosing technologies. As both a consumer item and the subject of local indigenous knowledge, commercial crop seeds provide a valuable window into these processes. Previous research on seed choices by cotton farmers …
Abstract: Respected Sir, Kindly find herewith a review of Bt-cotton benefits and concerns in India. The manuscript contains details of the experiences with the technology in India, and can be extended into a complete book. However I would like to highlight the following points and concerns for your kind consideration: There is a need for …
Abstract: Glyphosate, a post emergent herbicide, has become the backbone of no-till agriculture and is considered safe for animals. However, the impact of glyphosate on non-target organisms, especially on amphibians, is the subject of major concern and debate in recent times. We examined the toxic and genotoxic effects of Roundup, a commercial formulation of glyphosate, …
Abstract: Warangal District, Andhra Pradesh, India, is a key cotton‐growing area in one of the most closely watched arenas of the global struggle over genetically modified crops. In 2005 farmers adopted India’s first genetically modified crop, Bt cotton, in numbers that resemble a fad. Various parties, including the biotechnology firm behind the new technology, interpret …
Abstract: The Genetic Engineering Approval Committee’s approval of Bt brinjal, the first genetically modified crop for human consumption in India, has sparked off protests across the country. This article questions the so-called benefits of GM crops and highlights some major concerns. These include: inadequately addressed health and environmental risks, inadequate safety guidelines, a lack of …
Abstract: Widespread planting of maize throughout the agricultural Midwest may result in detritus entering adjacent stream ecosystems, and 63% of the 2009 US maize crop was genetically modified to express insecticidal Cry proteins derived from Bacillus thuringiensis. Six months after harvest, we conducted a synoptic survey of 217 stream sites in Indiana to determine the …
