ABSTRACT: Glyphosate is a broad-spectrum herbicide capable of controlling a wide range of weed. It uses could cause the occurrence of residues in conventional or genetically modified crops. For this purpose, grains (soybean and corn) and cotton seeds were sampled from commercial areas in 2012/2013 to 2017/2018 seasons in different Brazilian agricultural regions to monitor glyphosate residues levels and its metabolite (aminomethylphosphonic acid - AMPA) after different managements. The glyphosate residues levels in genetically modified corn (GM) ranged from no detected (ND) to 0.15 mg kg-1, in GM soybean values ranged from ND to 2.81 mg kg-1 and in GM cotton ranged from ND to 1.78 mg kg-1. AMPA residues levels indicated a correlation with the glyphosate residues. Glyphosate residues levels in soybean and corn grains and cotton seeds were within the Maximum Residue Limits (MRLs) established by ANVISA and Codex Alimentarius.

Abstract GM crops or Genetically Modified crops are attracted a wide range of media attention in recent years and continues to do so. Media given awareness about the genetically modified crops to public. They reported the uses and drawbacks of the GM crops. The technique offers with regards to the range of advantages of the use of genetically modified crops. In the Pioneer stage of the production of GM crops, two different sectors of concern have been evolved, which includes impact on the agriculture and dangerous to human life. Safety of the eatables have a vital role in the world. The issue can be reduced by enhancing the productivity and quality of the crop. Genetic manipulation technology depends on the MiRNA, it is one of the main problem-solving methods, which influence the environmental product formation through improving major rules used for miRNAs modification and its objectives in GM plants, it contains constitutive, induction to stress, or specific tissue expression of micro RNAs or their aim, RNA gene silencing mechanism, micro-RNA-resistant target and gene expressions. Genetically Modified Organisms is one of the major focuses in biomedical research from 1980s. Since, Genetically Modified models with animal enable researchers for treatment of human genetic diseases. Genetically Modified microorganisms, crops, and animals are used for the production of drugs that are complex by which helps the generation to vaccines that are cheaper. However, this article+ more focused on the human health associated with the genetically modified foods and role of miRNAs in respected to GM food products.

Herbicide Use

Monarch butterfly (Danaus plexippus) decline over the past 25 years has received considerable public and scientific attention, in large part because its decline, and that of its milkweed (Asclepias spp.) host plant, have been linked to genetically modified (GM) crops and associated herbicide use. Here, we use museum and herbaria specimens to extend our knowledge of the dynamics of both monarchs and milkweeds in the United States to more than a century, from 1900 to 2016. We show that both monarchs and milkweeds increased during the early 20th century and that recent declines are actually part of a much longer-term decline in both monarchs and milkweed beginning around 1950. Herbicide-resistant crops, therefore, are clearly not the only culprit and, likely, not even the primary culprit: Not only did monarch and milkweed declines begin decades before GM crops were introduced, but other variables, particularly a decline in the number of farms, predict common milkweed trends more strongly over the period studied here.

Forms Of Knowledge

A fierce controversy over genetically modified (GM) crops has been raging in India for over two decades. Analyzing India’s regulatory regime for GM crops, this article focuses on the modes through which state bureaucracies know the environment. It argues that two epistemologies - scientific and legal-administrative – underpin environment protection. By unraveling the course of regulatory disputes, I demonstrate that bureaucracies are not just hierarchically divided but are also segmented by horizontal, functional specializations. There is thus an inherent ambiguity lodged between environment as a technical discourse and as statecraft. This ambiguity both fosters and constrains democratic participation in policy decisions and can even partially disrupt power relations in unanticipated ways.
