“…It has been used extensively in conjunction with genetically modified crops since 1996 [14,15]. It is estimated that 91% of the soybeans, 22% of the corn, and 23% of the cotton crop hectares in the United States were planted as herbicide-tolerant varieties in 2009 ( [16]; http://www.ers.usda.gov/Data/BiotechCrops/).…”

Abstract-This is the first report on the ambient levels of glyphosate, the most widely used herbicide in the United States, and its major degradation product, aminomethylphosphonic acid (AMPA), in air and rain. Concurrent, weekly integrated air particle and rain samples were collected during two growing seasons in agricultural areas in Mississippi and Iowa. Rain was also collected in Indiana in a preliminary phase of the study. The frequency of glyphosate detection ranged from 60 to 100% in both air and rain. The concentrations of glyphosate ranged from <0.01 to 9.1 ng/m 3 and from <0.1 to 2.5 mg/L in air and rain samples, respectively. The frequency of detection and median and maximum concentrations of glyphosate in air were similar or greater to those of the other high-use herbicides observed in the Mississippi River basin, whereas its concentration in rain was greater than the other herbicides. It is not known what percentage of the applied glyphosate is introduced into the air, but it was estimated that up to 0.7% of application is removed from the air in rainfall.

“…In one study, it was reported that air concentrations of glyphosate were below 15.7 mg/m 3 during silvicultural spraying periods [29]. Thus, the occurrence and behavior of atmospheric glyphosate are still largely unknown even though glyphosate is the most widely used herbicide in the world [15,30].…”

“…Since 1996, because of a very high level of adoption of genetically modified glyphosate-resistant crops (that is, 80 million Ha in 2006 in Argentina, Brazil, Canada and USA), glyphosate has been intensively used across important agricultural regions (reviewed by Dill et al, 2008). In a relatively short period of time, large-scale usage of glyphosate as a principal tool for weed control in glyphosate-resistant crops without diversity has resulted in glyphosate-resistant weeds and shifts in weed communities (reviewed in Owen, 2008;Powles, 2008).…”

Evolution of glyphosate resistance in a Lolium rigidum population by glyphosate selection at sublethal doses

2009

The majority of the documented cases of field-evolved herbicide-resistant weed biotypes established that single major genes confer glyphosate resistance. However, the contribution of minor genes endowing substantial plant survival at sublethal herbicide doses may be a potential complementary path to herbicide resistance evolution in weed populations under selection. Here, we subjected a number of susceptible individuals of Lolium rigidum to recurrent glyphosate selection to test the potential for sublethal glyphosate doses to additively select for glyphosate resistance. After 3-4 cycles of glyphosate selection in two distinct environments, the progenies of the initially susceptible population were shifted toward glyphosate resistance. The results indicate progressive enrichment of minor gene trait(s) contributing toward plant survival in the glyphosate-selected progenies. After three generations of selection, the estimated LD 50 values were doubled compared with the original population and up to 33% plant survival was obtained in the glyphosate-selected progeny at the recommended glyphosate label rate. This level of resistance probably was the maximum shift achievable with sublethal glyphosate dose selection in this small population. Cross-pollination was a crucial factor enabling the rapid rate of accumulation of minor glyphosate resistance gene trait(s) that are likely to be present at a relatively high frequency in a small susceptible population. The mechanistic basis of the moderate glyphosate resistance level selected by sublethal glyphosate doses remains unknown and warrants future research. Studying the main factors influencing the evolution of resistant weed populations is crucial for understanding, predicting and managing herbicide resistance.

“…Long-term differences have had an affirmative environmental issue by diminishing soil erosion [21], fueling the needs for soil cultivation [22], and numbering herbicides with groundwater advisories [23], leading to a slight reduction in the overall environmental impact quotient of herbicide use [24,25]. Because of the adoption of herbicide-resistant crops, conservation tillage used in crop production has increased [18,26,27], and the volume of herbicides used in HRCs has decreased [28]. Finally, the effect on soil and plant microbial populations has not been shown to be a potential environmental risk [29,30].…”
