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 concerns over testing and corporate control of food, but by
its clash with the Ayurvedic medical establishment. GM brinjal may outcross with wild
relatives commonly used in Ayurvedic medicine, and claims that outcrossing would not
affect medical efficacy miss the point. Ayurveda emphasizes polyherbal treatments and
has developed an epistemology oriented towards complex combinations of compounds.
As such it does not recognize the authority of specific studies of transgene effects. The
conflict is not with genetic modification per se, but with the reductionism that is central
to the biotechnology approvals process. This opposition has played a significant role in
the government moratorium on the plant.

Abstract (provisional)

Background

The global area under brinjal cultivation is expected to be 1.85 million hectare with total fruit production about 32 million metric tons (MTs). Brinjal cultivars are susceptible to a variety of stresses that significantly limit productivity. The most important biotic stress is caused by the Brinjal Fruit and shoot Borer (FSB) forcing farmers to deploy high doses of insecticides; a matter of serious health concern. Therefore, to control the adverse effect of insecticides on the environment including the soil, transgenic technology has emerged as the effective alternative. However, the reports, regarding the nature of interaction of transgenic crops with the native microbial community are inconsistent. The effect of a Bt transgenic brinjal expressing the bio-insecticidal protein (Cry1Ac) on the rhizospheric community of actinomycetes has been assessed and compared with its non-transgenic counterpart.

Results

Significant variation in the organic carbon observed between the crops (non-Bt and Bt brinjal) may be due to changes in root exudates quality and composition mediated by genetic attributes of Bt transgenic brinjal. Real time quantitative PCR indicated significant differences in the actinomycetes- specific 16S rRNA gene copy numbers between the non-Bt (5.62-27.86) x 1011 g-1 dws and Bt brinjal planted soil (5.62-24.04) x 1011 g-1 dws. Phylogenetic analysis indicated 14 and 11, actinomycetes related groups in soil with non-Bt and Bt brinjal crop, respectively. Micrococaceaea and Nocardiodaceae were the dominant groups in pre-vegetation, branching, flowering, maturation and post-harvest stage. However, Promicromonosporaceae, Streptosporangiaceae, Mycobacteriaceae, Geodermatophilaceae, Frankiaceae, Kineosporaceae, Actisymmetaceae and Streptomycetaceae were exclusively detected in a few stages in non-Bt brinjal rhizosphere soil while Nakamurellaceae, Corynebactericeae, Thermomonosporaceae and Pseudonocardiaceae in Bt brinjal counterpart.

Conclusion

Field trails envisage that cultivation of Bt transgenic brinjal had negative effect on organic carbon which might be attributed to genetic modifications in the plant. Changes in the organic carbon also affect the actinomycetes population size and diversity associated with rhizospheric soils of both the crops. Further long-term study is required by taking account the natural cultivar apart from the Bt brinjal and its near-isogenic non-Bt brinjal with particular reference to the effects induced by the Bt transgenic brinjal across different plant growth stages.

Transgene Flow from Bt Brinjal: a real Risk?

http://www.cell.com/trends/biotechnology/fulltext/S0167-7799(13)00068-1

Bt brinjal too can create super weeds. 

Gene flow from a transgenic plants has remained a contentious issue. In the absence of experimental data, the task to pinpoint exactly as to how much is the potential risk, especially in centres of diversity, becomes daunting. The GM industry has often used lack of experimental data to show there is no cause for concern. It has happened in India, in the case of Bt cotton, and more recently when the moratorium on Bt brinjal came in 2010.

John Samuels of the Novel Solanaceae Crops Project, Penzance, Cornwall, UK, has raised some valid concerns, based on available data, in an excellent paper published in Trends in Biotechnology (Vol 31, Issue 6, June 2013). Admitting that transgene flow from Bt brinjal to wild, weedy and cultivated relatives is a major biosafety concern, he writes in an article Transgene Flow from Bt Brinjal: a real Risk?(URL: http://www.cell.com/trends/biotechnology/fulltext/S0167-7799(13)00068-1): “in preliminary risk assessment tests in India in 2007, only four spiny species were tested for interfertility with S.melongena  (http://www.envfor.nic.in/divisions/csurv/geac/bt_brinjal.html). They found only Solanum incanumL. (the nearest wild relative of brinjal) to be crossable; however, the production of hybrid progeny was not investigated.” With such limited scientific studies available, obviously gene flow was considered to be not much of a problem.

Citing various reasons like inadequate experimental methodologies and erroneous nomenclature of the parent species, John Samuel tells us that the biosafety implications of hybridisation remained compromised. Looking through the research data now available, he says that six wild relative species and four cultivated species have the potential to crossbred with the transgenic Bt brinjal. I have taken this table out from the article for an easy understanding.

Table 1 Solanum species of India known to cross with brinjal

His conclusion: “Furthermore, the risk assessment of pollen-mediated transgene flow from Bt brinjal, if cultivated in Bangladesh or the Philippines, should not rely on the inadequate, previously undertaken ERA (Environmental Risk Assessment) tests.” Hope the scientists as well as the science administrators are listening. Especially in the light of latest revelations that show how super weeds are becoming a nuisance in United States and Canada.

Chargesheet against Bt firm in biopiracy case

COIMBATORE: A chargesheet has been filed against Maharashtra Hybrid Seeds Company (Mahyco), a subsidiary of Monsanto, the US agri business firm, for violating the bio-piracy laws in developing Bt Brinjal variety by using genes of local brinjal varieties without prior permission, according to Balakrishna Pasupati, chairman of National Biodiversity Authority.

Pasupathi spoke to TOI on the sidelines of a workshop on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) at the Institute of Forest Genetics and Tree Breeding (IFGTB) in the city. “We were convinced that there could have been a possible misappropriation of Indian biological varieties,” he said refusing to divulge more details. The chargesheet was submitted at the Dharwad principal sessions court against Mahyco and the University of Agricultural Sciences at Dharwad, he said.

Meeting of Scientific Advisory Council of PM on Biotechnology and Agriculture

Scientific and technological breakthroughs of a transformational nature relevant to economic and social development happen only once in a while. The emergence of such technologies evokes responses according to a pattern: initial excitement, followed by strong expression of concern and then emergence of a balanced perspective. Transformational technologies in the past, such as steam engine, electricity and other sources of energy, vaccines & immunization and internet have all followed this trend. Molecular biology and biotechnologies developed through major investments in science and technology globally have a transformational potential for benefitting agriculture and health and it is time now to evolve a balanced perspective.

The members of the Scientific Advisory Committee (SAC) to the Prime Minister deliberated on the important issue of application of biotechnology for social and economic advancement of the country particularly in the area of agriculture. There are uncertainties in some segments of society that need to be objectively and fairly addressed. The members of the SAC are concerned that a science informed, evidence based approach is lacking in the current debate on biotechnologies for agriculture. There are some key aspects that merit consideration.

Do we need new technologies for agriculture? Indian agriculture productivity is seen by the less discerning to be adequate for today’s needs but what is ignored is that vast numbers of our countrymen are unable to consume the required food and nutrients because of difficult access. As our current efforts to address the issue of access bear fruit, the need for food and quality nutrients’ will grow rapidly. Land availability and quality, water, low productivity, drought and salinity, biotic stresses, post harvest losses are all serious concerns that will endanger our food and nutrition security with potentially serious additional affects as a result of climate change. Accordingly, strategies for agriculture in future must be based on higher yields, concomitant with reduction in resource inputs. This will require a judicious blend of traditional breeding and new technologies, non-transgenic & transgenic. This situation in developed countries such as in Europe; quite in contrast, as there is no dearth of food and a small proportion of people engage in agriculture.

The assessment of safety and efficacy of biotechnology products has to be evaluated through an appropriate regulatory system on a case by case basis, as for drugs and vaccines. In general, endorsement or opposition to a generic technology is scientifically not rational and safety and efficacy must be judged on product basis. The need for an appropriate regulatory mechanism in the country has been rightly emphasized in the Swaminathan Committee Report. The existing system based on RCGM and GEAC have given us large experience and its operational guidelines are generally sound and as per the best international norms such as guidelines by OECD. The effort now should be on effective implementation. Regulatory systems evolve with experience and review based redesign. Little is served by focusing on the flaws only.

The proposed Bill for establishment of a national Biotechnology Regulatory Authority of India (BRAI), 2012 is with the Parliament, it deserves to be examined on a priority basis. The key characteristics of effective regulatory system hardly need reiteration; sound scientific expertise within the organization and through independent panels, access to scientific tools for assessment of safety and efficacy and processes that ensure transparency, freedom from conflict and competence. This can only be delivered by a robust and independent system. The focus of the regulatory authority has to be on assessment of safety and efficacy. Commercialization and deployment of agriculture biotechnology products requires expertise in social and economic evaluation and post-deployment surveillance. This requires effective inputs of central and state agriculture ministries.

The experience with the deployment of Genetically Modified (GM) crops worldwide is growing at a steady pace and should be taken into consideration. GM crops of maize, soya, potato, sugar beet, canola, cotton and alfalfa and grown across the globe covering 160 million hectares by 2011. While each concern must be addressed through scientific approach, we believe the performance of GM crops released through oversight by regulators has been very positive. This view has been endorsed by major scientific bodies of the world. This is clearly true of our own experience with introduction of Bt Cotton in India wherein the benefits have been major. It is our view that biotechnology research and development should target important national needs, products should be developed under careful regulatory oversight and deployed in a way that access and affordability to entire farming community, particularly small and marginal farmers, is ensured.

There are other relevant issues that merit attention. Some of the opposition to GM crops in the country results from fear of domination by multinational companies. One way to address this concern is to invigorate and further strengthen the relevant scientific capacities of our institutions in public sector, universities and Indian companies. The current debate, unfortunately, is demoralizing and isolating our Scientists in the sector whose skills have been built with painstaking effort and large investment. The policy confusion will also keep the brightest away from this field of research. Our Scientists are fully aware of the social realities in this country and have widely endorsed the judicious adoption of traditional breeding with biotechnologies, non-transgenic and transgenic, as appropriate. There is concern about the costs at which seed is available to our farmers, particularly the poor farmers. This requires an appropriate public policy and action. The industry must shoulder responsibility by ensuring this through constructive dialogue with the government. Market mechanisms alone will not be sufficient.

The precautionary approach is inherently sound but it must be applied through a science based safety assessment and social and economic analysis for deployment. We make the following recommendation for kind consideration:-

1) The current regulatory system for recombinant products administered under Rules (1989) of EPA Act, 1986 should be reformed till BRAI is in place.

(i) RCGM and GEAC should be the sole authority for biosafety and bio-efficacy assessment of all recombinant products. Decision on commercial use of biotechnology produced crops should be taken by the Agriculture Ministries/Department of Central and State Governments as per existing policies and regulations on crops. For medical products Central Drugs Standard Control Organization (CDSCO) of Ministry of Health and Family Welfare, Government of India would approve commercialization as of now.

(ii) High Level dialogue with State governments to streamline clearances for conduct of multi-location “Confined field trials” – a scientific pre-requite in all countries for meaningful decision making on approvals or otherwise.

(iii) A Biotechnology Regulatory Secretariat with high level of scientific and technical trained manpower should be established to support RCGM and GEAC.

(iv) GEAC and RCGM should have full time Chairpersons. The Chairman of GEAC, may be of Special Secretary Status for 3 year period and RCGM one level lower. Chairman of RCGM be the Co-Chair in GEAC and not the expert nominee of Department of Biotechnology. For greater synergy at least three members should be common between RCGM and GEAC.

(v) The public needs to be informed of every decision.

2) The Bill pending with Parliament, i.e. BRAI 2012, should be debated with open mind. It would be appropriate if administrative organization could be Cabinet Secretariat because of the involvement of multiple ministries. The Bill when examined by appropriate parliament committee would be opened up for wider debate and discussions for shaping the draft legislation into a model regulatory framework.

3) The capacity for regulatory testing of new technologies in agriculture in public sector laboratories should be strengthened, supplemented with a system of notification and accreditation. This can be initiated even while the BRAI becomes a reality.

4) Research and infrastructure of state agriculture universities and colleges be strengthened for addressing the locations- specific needs of the states and regions and generate expertise.

5) Priority should be given to strengthen State Government departments and laboratories dealing with agriculture inputs, including GM or non GM seeds, extension and education of farmers through major programmes and investments for capacity building tailor made to the needs of the region.

Bt Brinjal is safe, claims NIN

http://timesofindia.indiatimes.com/city/hyderabad/Bt-Brinjal-is-safe-claims-NIN/articleshow/16344961.cms

HYDERABAD: Is Bt Brinjal safe? The demonisation of BT crops got a push with the parliamentary committee on agriculture in its report submitted last month commenting that transgenics in food crops would be fraught with unknown consequences. But the Hyderabad-based National Institute of Nutrition (NIN) of the Indian Council of Medical Research (ICMR) says that Bt Brinjal is safe.

A voluminous report on the laboratory experiments carried out on the safety of Bt Brinjal was submitted to the Review Committee on Genetic Manipulation ( RCGM) of the Department of Biotechnology, ministry of science and technology.

B Dinesh Kumar, deputy director, Food and Drug Toxicology Research Centre, at the NIN told TOI that in every respect, Bt Brinjal was found to be safe. “What now needs to be done is open field trials,” Dinesh Kumar said.

However, the problem arises here. In order to analyse the effects of Bt Brinjal in human consumption, it first needs to be introduced in the market. The Genetic Engineering Approval Committee (GEAC) will then need to allow introducion of Bt Brinjal, at least in a limited way, so that the effects can be evaluated.

When Bt Brinjal was sought to be introduced in the market a few years ago, it led to a controversy. However, on February 9, 2010, the ministry of environment and forests imposed a moratorium on Bt Brinjal. In the absence of scientific consensus and opposition from state governments and others, the ministry decided to impose a moratorium on the commercialisation of Bt Brinjal until all concerns expressed by the public, NGOs, scientists and the state government were addressed adequately.

Among those actively opposed to the introduction of Bt Brinjal is P M Bhargava, founder-director of the Centre for Cellular and Molecular Biology, Hyderabad, who was nominated by the Supreme Court to the GEAC.

Bhargava who had even argued against Bt Cotton told the parliamentary committee on agriculture that GM organisms could be introduced only after adequate testing was done.

The pre-clinical tests conducted at the NIN show that Bt Brinjal is safe but activists who are against genetically modified crops need to be convinced about the study and its results.

జన్యుమార్పిడి పంటలపై మరిన్ని పరిశోధనలు, సరైన నియంత్రణ వ్యవస్థ లేకుండా ఫీల్డ్ ట్రయల్స్‌కు అనుమతించకూడదని పార్లమెంటరీ స్థాయీ సంఘం చేసిన సిఫార్సులపై దేశవ్యాప్తంగా చర్చ జరుగుతోంది. ఈ నేపథ్యంలో జన్యు మార్పిడి పంటలకు సంబంధించిన అంశాలపై పరిశ్రమవర్గాలు చెబుతున్న దానికి, పరిశోధనలలో తేలుతున్న నిజాలకు మధ్య చాలా వ్యత్యాసం కనిపిస్తుంది. ఈ నేపథ్యంలో జన్యుమార్పిడి పంటలకు సంబంధించిన వాస్తవాలు, భ్రమలపై అధ్యయనం చేస్తున్న ‘సెంటర్ ఫర్ సస్టేయనబుల్ అగ్రికల్చరల్’ సంస్థ ఎగ్జిక్యూటివ్ డైరక్టర్ జి.వి. రామాంజనేయులుతో ఈ వారం ముఖాముఖి..

బీటీ విత్తనాల వల్ల అనేక ప్రయోజనాలు ఉన్నాయని కంపెనీలు ప్రచారం చేస్తున్నాయి. కాని పరిశోధనలలో తేలుతున్న నిజాలు వేరే విధంగా ఉంటున్నాయి..?
బీటీ విత్తనాలు కరువు పరిస్థితులను కూడా తట్టుకొని నిలబడతాయని.. దిగుబడి ఎక్కువ వస్తుందని.. ఈ పంటలకు కలుపు మందులు వేయాల్సిన అవసరం లేదని.. పురుగులు ఎక్కువ రావనే ప్రచారం జరుగుతోంది. కాని ఈ ప్రచారం నిజం కాదు. బీటీ విత్తనాల వల్ల దిగుబడి బాగా పెరిగిందనేది పూర్తి అవాస్తవం. ఉదాహరణకు బీటీ పత్తిని తీసుకుందాం.

2001 నుంచి 2005 దాకా మన దేశంలో పత్తి దిగుబడి 78 శాతం పెరిగింది. దీనిలో కేవలం ఆరు శాతం విస్తీర్ణంలో మాత్రమే బీటీ విత్తనాలను వేశారు. ఇదే విధంగా 2006-11 సంవత్సరాల మధ్య చూస్తే- మొత్తం విస్తీర్ణం 80 శాతం పెరిగితే- దానిలో దిగుబడి రెండు శాతం పెరిగింది. ఈ రెండింటి «ఆధారంగా చూస్తే దిగుబడి పెరగటానికి బీటీ విత్తనాలు మాత్రమే కారణం కాదని అర్థమవుతుంది. అదనంగా సాగు కిందకు వచ్చిన భూమి పెరగటం మొదలైన ఇతర కారణాలు చాలా ఉన్నాయి.

వాస్తవానికి ప్రపంచవ్యాప్తంగా బీటీ విత్తనాలు వేసిన ప్రాంతాల్లో దిగుబడులు తగ్గిపోతున్నాయి. ఇక బీటీ విత్తనాలు పురుగులను తట్టుకుంటాయని చేస్తున్న వాదనలో కూడా నిజం లేదు. పురుగులు బీటీ విత్తనాలను తట్టుకొనే శక్తిని పెంచుకున్నాయి. మన ఆంధ్రప్రదేశ్ ఉదాహరణనే తీసుకుంటే- గులాబీ రంగు తొలిచే పురుగును బీటీ పత్తి విత్తనాలు తట్టుకోలేకపోతున్నాయని మోన్‌శాంటోనే ప్రకటించింది. ఇదే విధంగా బీటీ విత్తనాలు కాయి తొలిచే పురుగులను కూడా తట్టుకోలేకపోతున్నాయి.

బీటీ పత్తికి సంబంధించి కంపెనీలు గుజరాత్‌ను ఒక రోల్ మోడల్‌గా ప్రచారం చేస్తూ ఉంటాయి. గుజరాత్‌లో నిజంగానే బీటీ పత్తి విజయం సాధించిందా?
గుజరాత్ ప్రభుత్వ నివేదికల ఆధారం చూస్తే పత్తి సాగు చేసే ప్రాంతం దాదాపు 45 శాతం పెరిగింది. అదనంగా సాగులోకి వచ్చిన ప్రాంతం 43 శాతం పెరిగింది. వీటికి తోడుగా హైబ్రీడ్ పత్తి వేసిన ప్రాంతం కూడా పెరిగింది. ఈ కారణాల వల్ల గుజరాత్‌లో దిగుబడి పెరిగింది తప్ప- బీటీ విత్తనాల వల్ల మాత్రమే కాదు. ఇక్కడ మనం ఒక విషయాన్ని తప్పకుండా చెప్పుకోవాలి. చాలా సార్లు జన్యు మార్పిడి పంటల వల్ల కలిగే ప్రయోజనాలను ప్రచారం చేసేవారు- తమ వద్ద ఉన్న సమాచారాన్ని పూర్తిగా అందించరు. తమకు అనుకూలంగా కనిపించే కొంత సమాచారాన్ని ఇస్తారు. దీనిని చూస్తే- అంతా సజావుగా ఉన్నట్లు అనిపిస్తుంది. కాని ఇది నిజం కాదు.

బీటీ వంకాయ ఫీల్డ్ ట్రయల్స్‌కు సంబంధించి పెద్ద వివాదం నడుస్తోంది కదా. దీని వెనకున్న కథ ఏమిటి?
బీటీ వంకాయ విత్తనాల వల్ల కలిగే దుష్ఫరిమాణాలను జాగ్రత్తగా అధ్యయనం చేయకుండా అనుమతించవద్దని ప్రభుత్వం ఏర్పాటు చేసిన నిపుణుల కమిటీ సిఫార్సు చేసింది. ఆంధ్రప్రదేశ్‌తో సహా పది రాష్ట్రాలు బీటీ వంకాయ ఫీల్డ్ ట్రయల్స్‌ను అనుమతించబోమని ప్రకటించాయి. అయితే మనం ఇక్కడ ఒక విషయాన్ని గమనించాలి. జన్యు మార్పిడి పంటల వల్ల వచ్చే లాభనష్టాలను సమీక్షించటానికి మన దగ్గర సరైన నియంత్రణా వ్యవస్థ లేదు. ఉదాహరణకు బీటీ పత్తినే తీసుకుందాం. దీని లాభనష్టాలను 2005లో చివరి సారి సమీక్షించారు. ఆ తర్వాత ఎప్పుడూ మళ్లీ సమీక్ష జరగలేదు.

బీటీ పత్తి వల్ల అనేక దుష్ఫరిణామాలు ఏర్పడుతున్నాయని ఈ లోపులో అనేక పరిశోధనలు వచ్చాయి. ఉదాహరణకు వరంగల్ జిల్లాలో బీటీ పత్తి ఆకులు తిని పశువులు మరణించాయని కొన్ని పరిశోధనలు చెబుతున్నాయి. ఇలాంటి వాటిని ప్రభుత్వం వెంటనే పరిగణనలోకి తీసుకోవాలి. చాలా సార్లు ప్రభుత్వం ఈ చర్యలు తీసుకోదు. పైగా జన్యుమార్పిడి పంటలపై పరిశోధనలకు పెద్ద ఎత్తున నిధులను కేటాయించి, తామే పరిశోధనలు చేస్తామని ప్రకటిస్తోంది కూడా. ఈ మొత్తం వ్యవహారం వెనక పెద్ద పెద్ద కంపెనీల లాబీయింగ్ కూడా ఉంటుంది.

మన కన్నా ముందే కొన్ని దేశాలలో జన్యు మార్పిడి పంటల పరిజ్ఞానం ప్రవేశించింది కదా. వారి అనుభవాలేమిటి?
ప్రపంచంలో పన్నెండు దేశాల్లో మాత్రమే జన్యు మార్పిడి పంటలను వేస్తున్నారు. వారి అనుభవాలు కూడా అంత సంతృప్తికరంగా లేవు. అమెరికాలో తాజాగా చేసిన పరిశోధనలలో- ఈ పంటల వల్ల దిగుబడి బాగా తగ్గుతోందని తేలింది. అంతే కాకుండా ఈ పంటలను తట్టుకొనే చీడ పురుగులు తయారయ్యాయి. వీటిని సూపర్ వీడ్స్ అని పిలుస్తున్నారు.

దీనికి తోడు పేటెంట్స్ పేరిట మొత్తం విత్తన మార్కెట్ అంతా కొన్ని కంపెనీల చేతిలోకి వెళ్లిపోతుంది. ఈ ప్రక్రియ మన దేశంలో కూడా ప్రారంభమయింది. ఉదాహరణకు మన దేశంలో బీటీ పత్తి విత్తన మార్కెట్‌లో 98 శాతం మాన్‌శాంటో చేతిలోనే ఉంది. ఇక్కడ ఇంకో ఆశ్చర్యం కలిగించే విషయాన్ని చెబుతాను. బీటీ విత్తనాలకు సంబంధించిన అంశాలలో కంపెనీని ప్రభుత్వం నియంత్రించాలి. కాని పరిస్థితి ఆ విధంగా లేదు. చాలా సార్లు కంపెనీయే ప్రభుత్వంపై కేసులు పెట్టింది.

ఈ పరిస్థితిని చక్కదిద్దటానికి ఉన్న మార్గాలేమిటి?
ప్రత్యామ్నాయ వ్యవసాయ పద్ధతులపై ప్రభుత్వం శ్రద్ధ చూపించాలి. పరిశోధనలకు నిధులను కేటాయించాలి. పరిశోధనాశాలలకు అవసరమైన మౌలిక వసతులు కల్పించాలి. వీటిన్నింటితో పాటుగా నియంత్రణ వ్యవస్థను కట్టుదిట్టం చేయాలి. ఈ విత్తనాలకు సంబంధించిన అంశాలలో కొందరిని బాధ్యులను చేయాలి. ప్రస్తుతం ఈ పద్ధతి లేకపోవటం వల్ల ఇటు ప్రభుత్వం కాని, ఈ విత్తనాలను అనుమతించిన రెగ్యులేటర్ కాని, తయారు చేసిన కంపెనీ కాని బాధ్యత తీసుకోవటం లేదు. దీని వల్ల సామాన్య రైతులు నష్టపోతున్నారు.
